Mobilization of seed storage lipid by Arabidopsis seedlings is retarded in the presence of exogenous sugars. (1/1763)

BACKGROUND: Soluble sugar levels must be closely regulated in germinating seeds to ensure an adequate supply of energy and building materials for the developing seedling. Studies on germinating cereal seeds indicate that production of sugars from starch is inhibited by increasing sugar levels. Although numerous studies have focused on the regulation of starch metabolism, very few studies have addressed the control of storage lipid metabolism by germinating oilseeds. RESULTS: Mobilization of storage lipid by germinating seeds of the model oilseed plant Arabidopsis thaliana (L.) Heynh. occurs at a greatly reduced rate in the presence of exogenous glucose or mannose, but not in the presence of equi-molar 3-O-methylglucose or sorbitol. The sugar-insensitive5-1/abscisic acid-insensitive4-101 (sis5-1/abi4-101) mutant is resistant to glucose inhibition of seed storage lipid mobilization. Wild-type seedlings become insensitive to glucose inhibition of storage lipid breakdown within 3 days of the start of imbibition. CONCLUSIONS: Growth in the presence of exogenous glucose significantly retards mobilization of seed storage lipid in germinating seeds from wild-type Arabidopsis. This effect is not solely due to the osmotic potential of the media, as substantially higher concentrations of sorbitol than of glucose are required to exert significant effects on lipid breakdown. The inhibitory effect of glucose on lipid breakdown is limited to a narrow developmental window, suggesting that completion of some critical metabolic transition results in loss of sensitivity to the inhibitory effect of glucose on lipid breakdown.  (+info)

Antisense expression of an Arabidopsis omega-3 fatty acid desaturase gene reduces salt/drought tolerance in transgenic tobacco plants. (2/1763)

A wound-inducible Arabidopsis plastid omega-3 fatty acid desaturase (fad7) cDNA was obtained. Transgenic tobacco plants were produced by integration of the antisense fad7 DNA fragments under the control of a CaMV 35S promoter into the genome. Two transgenic T1 lines, AsFAD714 and 716, showed a strong expression of the antisensefad7 and reduced amounts of linolenic acid compared with the control plants. The two T1 lines were highly sensitive to dehydration conditions, showing growth retardation on the MS medium in the presence of 250 mM NaCl, and severe wilting under drought conditions. The expression of the transcriptional factor gene abf4 transducing ABA-dependent signal in response to drought stress was strongly induced in the control plants, but far less in the AsFAD716 line. This suggests that the inhibitory effect of the antisense fad7 gene expression on the ABF-mediated stress-responsive gene regulation may reduce drought tolerance in the AsFAD716 line. However, no significant difference in the ABA concentration was found between the control and the AsFAD716 line under normal and drought conditions.  (+info)

De-etiolated 1 and damaged DNA binding protein 1 interact to regulate Arabidopsis photomorphogenesis. (3/1763)

BACKGROUND: Plant development is exquisitely sensitive to light. Seedlings grown in the dark have a developmentally arrested etiolated phenotype, whereas in the light they develop leaves and complete their life cycle. Arabidopsis de-etiolated 1 (det1) mutants develop like light-grown seedlings even when grown in the dark. DET1 encodes a nuclear protein that appears to act downstream from multiple photoreceptors to regulate morphogenesis and gene expression in response to light. However, its function has remained unknown. RESULTS: We used microarrays to examine defects in transcription in dark-grown det1 seedlings. We found extensive changes in gene expression, including many of the transcriptional responses observed in light-treated wild-type seedlings. We used an epitope-tagging approach to determine the basis of DET1 function. GFP-DET1 rescues the det1 phenotype, is localized to the nucleus, and forms an approximately 350 kDa complex, which is required for full DET1 activity. We affinity-purified the DET1 complex and identified an approximately 120 kDa copurifying protein that is the plant homolog of UV-Damaged DNA Binding Protein 1 (DDB1), a protein implicated in the human disease xeroderma pigmentosa. A null mutation in Arabidopsis DDB1A results in no obvious phenotype on its own, yet it enhances the phenotype of a weak det1 allele. CONCLUSIONS: DET1 and DDB1 interact both biochemically and genetically. In animal cells, DDB1 interacts with histone acetyltransferase complexes. The DET1/DDB1 complex may regulate gene expression in response to light via recruitment of HAT activity. Thus, DET1, whose sequence is conserved in both animals and plants, may play a direct role in the regulation of many genes.  (+info)

Contribution of the mevalonate and methylerythritol phosphate pathways to the biosynthesis of gibberellins in Arabidopsis. (4/1763)

Gibberellins (GAs) are diterpene plant hormones essential for many developmental processes. Although the GA biosynthesis pathway has been well studied, our knowledge on its early stage is still limited. There are two possible routes for the biosynthesis of isoprenoids leading to GAs, the mevalonate (MVA) pathway in the cytosol and the methylerythritol phosphate (MEP) pathway in plastids. To distinguish these possibilities, metabolites from each isoprenoid pathway were selectively labeled with (13)C in Arabidopsis seedlings. Efficient (13)C-labeling was achieved by blocking the endogenous pathway chemically or genetically during the feed of a (13)C-labeled precursor specific to the MVA or MEP pathways. Gas chromatography-mass spectrometry analyses demonstrated that both MVA and MEP pathways can contribute to the biosyntheses of GAs and campesterol, a cytosolic sterol, in Arabidopsis seedlings. While GAs are predominantly synthesized through the MEP pathway, the MVA pathway plays a major role in the biosynthesis of campesterol. Consistent with some crossover between the two pathways, phenotypic defects caused by the block of the MVA and MEP pathways were partially rescued by exogenous application of the MEP and MVA precursors, respectively. We also provide evidence to suggest that the MVA pathway still contributes to GA biosynthesis when this pathway is limiting.  (+info)

Characterization of a CK II protein kinase from etiolated oat seedlings. (5/1763)

Protein kinases play a central role in controlling the cellular metabolism of living organisms. A protein kinase was purified from etiolated oat seedlings by several steps of ion-exchange and affinity chromatographies. The kinase was a 150-kDa tetrameric protein and composed of three subunits of 34, 37, and 40 kDa proteins. The 34 and 40 kDa proteins had ATP binding sites, suggesting that they are catalytic subunits and that the 37-kDa protein is a regulatory subunit. In the in vitro phosphorylation of a crude oat cell extract, it intensively phosphorylated a serine residue of a 110-kDa protein. The 110-kDa protein was tentatively identified as a DNA topoisomerase I, based on an amino acid sequence homology. Phosphorylation of the 110-kDa protein by the kinase required ATP or GTP as a phosphoryl group donor. The kinase activity was inhibited by 50% at a concentration of 0.05 microg/ml heparin. These results, therefore, indicate that the purified kinase is a CK II protein kinase and may be involved in the regulation of DNA topoisomerase I activity.  (+info)

Annotation and BAC/PAC localization of nonredundant ESTs from drought-stressed seedlings of an indica rice. (6/1763)

To decipher the genes associated with drought stress response and to identify novel genes in rice, we utilized 1540 high-quality expressed sequence tags (ESTs) for functional annotation and mapping to rice genomic sequences. These ESTs were generated earlier by 3'-end single-pass sequencing of 2000 cDNA clones from normalized cDNA libraries constructed form drought-stressed seedlings of an indica rice. A rice UniGene set of 1025 transcripts was constructed from this collection through the BLASTN algorithm. Putative functions of 559 nonredundant ESTs were identified by BLAST similarity search against public databases. Putative functions were assigned at a stringency E value of 10(-6) in BLASTN and BLASTX algorithms. To understand the gene structure and function further, we have utilized the publicly available finished and unfinished rice BAC/PAC (BAC, bacterial artificial chromosome; PAC, P1 artificial chromosome) sequences for similarity search using the BLASTN algorithm. Further, 603 nonredundant ESTs have been mapped to BAC/PAC clones. BAC clones were assigned by a homology of above 95% identity along 90% of EST sequence length in the aligned region. In all, 700 ESTs showed rice EST hits in GenBank. Of the 325 novel ESTs, 128 were localized to BAC clones. In addition, 127 ESTs with identified putative functions but with no homology in IRGSP (International Rice Genome Sequencing Program) BAC/PAC sequences were mapped to the Chinese WGS (whole genome shotgun contigs) draft sequence of the rice genome. Functional annotation uncovered about a hundred candidate ESTs associated with abiotic stress in rice and Arabidopsis that were previously reported based on microarray analysis and other studies. This study is a major effort in identifying genes associated with drought stress response and will serve as a resource to rice geneticists and molecular biologists.  (+info)

Altered shoot/root Na+ distribution and bifurcating salt sensitivity in Arabidopsis by genetic disruption of the Na+ transporter AtHKT1. (7/1763)

Sodium (Na+) is toxic to most plants, but the molecular mechanisms of plant Na+ uptake and distribution remain largely unknown. Here we analyze Arabidopsis lines disrupted in the Na+ transporter AtHKT1. AtHKT1 is expressed in the root stele and leaf vasculature. athkt1 null plants exhibit lower root Na+ levels and are more salt resistant than wild-type in short-term root growth assays. In shoot tissues, however, athkt1 disruption produces higher Na+ levels, and athkt1 and athkt1/sos3 shoots are Na+-hypersensitive in long-term growth assays. Thus wild-type AtHKT1 controls root/shoot Na+ distribution and counteracts salt stress in leaves by reducing leaf Na+ accumulation.  (+info)

A simple alfalfa seedling infection model for Pseudomonas aeruginosa strains associated with cystic fibrosis shows AlgT (sigma-22) and RhlR contribute to pathogenesis. (8/1763)

A sensitive plant infection model was developed to identify virulence factors in nontypeable, alginate overproducing (mucoid) Pseudomonas aeruginosa strains isolated from cystic fibrosis (CF) patients with chronic pulmonary disease. Nontypeable strains with defects in lipopolysaccharide O-side chains are common to CF and often exhibit low virulence in animal models of infection. However, 1,000 such bacteria were enough to show disease symptoms in the alfalfa infection. A typical mucoid CF isolate, FRD1, and its isogenic mutants were tested for alfalfa seedling infection. Although defects in the global regulators Vfr, RpoS, PvdS, or LasR had no discernable effect on virulence, a defect in RhlR reduced the infection frequency by >50%. A defect in alginate biosynthesis resulted in plant disease with >3-fold more bacteria per plant, suggesting that alginate overproduction attenuated bacterial growth in planta. FRD1 derivatives lacking AlgT, a sigma factor required for alginate production, were reduced >50% in the frequency of infection. Thus, AlgT apparently regulates factors in FRD1, besides alginate, important for pathogenesis. In contrast, in a non-CF strain, PAO1, an algT mutation did not affect its virulence on alfalfa. Conversely, PAO1 virulence was reduced in a mucA mutant that overproduced alginate. These observations suggested that mucoid conversion in CF may be driven by a selection for organisms with attenuated virulence or growth in the lung, which promotes a chronic infection. These studies also demonstrated that the wounded alfalfa seedling infection model is a useful tool to identify factors contributing to the persistence of P. aeruginosa in CF.  (+info)

BAYUELO-JIMENEZ, Jeannette S. et al. Phosphorus-efficiency in maize germplasm at seedling stage from the Purhépecha Plateau. Rev. fitotec. mex [online]. 2012, vol.35, n.3, pp.199-208. ISSN 0187-7380.. Reduced phosphorus (P) availability in the soil is one of the main yield-limiting factors for maize (Zea mays L.) production, particularly on acid soils. Changes in root morphology and architecture are regulated by P availability and are particularly important for phosphorus acquisition. This study was conducted to evaluate the genotypic variability of maize from the Purhépecha Plateau in Michoacán, México, by quantifying P efficiency and root characteristics associated with P efficiency at seedling stage. The experiment was conducted under greenhouse conditions, in nutrient solution at low (1 µM) and high (1 mM) KH2PO4 availability. Plant growth traits, root architecture and morphology were evaluated for 7 d. Accessions differed greatly in plant growth, root morphology and P efficiency ...
Double-stemmed seedlings (DSS) will be favored by the growers because they can save the expense needed to purchase commercial seedlings. This is also true with grafted tomatoes since the price of grafted tomato seedlings is about 2 times higher than non-grafted ones. The plug seedling growers will also benefit from the increased demand for DSS if the production cost for DSS can be maintained at appropriate level. Two stem cuttings having two expanded leaves were taken from a seedling when the seedling had four expanded leaves and rooted in 32-cell trays filled with commercial soil mix. Lower stem cuttings having first and second leaves produced well-balanced DSS even without any plant bioregulator treatment whereas up upper stem cuttings having third and fourth leaves resulted in single-stem seedlings with very limited outgrowth of axillary shoot from the third node.

In this chapter, well cover caring for your cannabis seedlings. The seedling phase begins when the young plant first emerges from the seed and extends for the first few weeks of life. Seedlings are born with a pair of small round leaves called embryonic cotyledons, that formed inside the seed. The young seedling uses these leaves to bootstrap photosynthesis and growth processes through the seedling phase, which ends after the plant starts growing adult leaves with 5 and 7 points.. Primary Objective: During the seedling phase, the primary objective is to allow the plant to develop hearty leaves for photosynthesis, healthy roots to slurp water and nutrients and a sturdy stem to support it all. Its best to let the seedling do its job with minimum disturbance from the grower.. Optimal Environment: Think warm spring days in a humid understory, at the edge of a clearing. The light would be bright, but not too intense, and would shine between 12 and 16 hours a day. The soil would be mostly dry ...
Seeds of Arabidopsis contain ~40% of triacylglycerol. It is converted to sugar to support post germination growth. We identified an Arabidopsis T-DNA knockout mutant that was sugar dependent during early seedling establishment. Our study showed that the β-oxidation process involved in catabolising the free fatty acids released from the seed triacylglycerol was impaired in this mutant. This mutant was confirmed to be transcriptional null for the Protein Acyl Transferase 15, AtPAT15 (At5g04270), one of the 24 protein acyl transferases in Arabidopsis. Although it is the shortest AtPAT15 contains the signature Asp-His-His-Cys cysteine rich domain which is essential for the enzyme activity of this family of proteins. The function of AtPAT15 was validated because it rescued the growth defect of the yeast protein acyl transferase mutant akr1 and it was also auto-acylated in vitro. Transient expression of AtPAT15 in Arabidopsis and tobacco localized AtPAT15 in the Golgi apparatus. Taken together, our ...

The Oryza sativa L. F8 population derived from a cross between salt tolerance cv. Ahlemi Tarom and salt sensitive cv. Neda was used in the study. Germinated seeds floated on water for 3 d, and after were transferred to float on Yoshidas nutrient solution for 11 d. two weeks after sowing, the seedling was transferred to nutrient solution containing 51.19 mM NaCl (electrical conductivity 6 dSm-1) for 7 d, then NaCl concentration was increased to 163.8 mM (12 dSm-1) for further 7 d. After this period, the traits were measured. The linkage map was performed using F8 populations, 40 SSR markers, 16 ISSR markers (76 alleles), 2 IRAP markers (7 alleles) and iPBS marker (3 alleles). The map length was 1419 cM with an average distance of 13.07 cM between the 2 adjacent markers. The QTL analysis showed that a total of 73 QTLs were identified that controlled 20 traits under normal and stress conditions. Among the QTLs, qCHLN-8, qSLN-8, qWLN-3, qWLN-9, qLAN-3, qLAN-8 and qLAN-9, qRFWN-1, qRFWN-3b and qRFWN-8, qFBN

[Objective] The aim was to screen the optimum seedling substrate for Stromanthe sanguinea.[Method] With S.sanguinea as tested material,corn stalk,peat and garden soil as seedling substrates,the physical and chemical indexes of S.sanguinea seedlings on each kind of straw seedling substrates were studied.[Result] The bulk density and total porosity of seedling substrate prepared by corn stalk with different proportions and garden soil were decreased with the decomposition of corn stalk and growth of crop.The nitrogen,phosphor and potassium content in substrate showed downtrend basically.Among them,the descending speed of each element in treatment with corn stalk-garden soil ratio being 3 to 7 was faster and under the treatment,the seedlings adapted the growth environment gradually,and had strong growth vigor and better development in the substrate through observing the exterior growth vigor of S.sanguinea seedlings.[Conclusion] The substrate with corn stalk-garden soil ratio being 3 to 7 was better
Rice crop is sensitive to cold stress at seedling stage. A panel of population representing 304 shortlisted germplasm lines was studied for seedling stage chilling tolerance in indica rice. Six phenotypic classes were exposed to six low temperature stress regimes under control phenotyping facility to investigate response pattern. A panel of sixty six genotypes representing all phenotypic classes was used for ensuring genetic diversity, population structure and association mapping for the trait using 58 simple sequence repeat (SSR) and 2 direct trait linked markers. A moderate level of genetic diversity was detected in the panel population for the trait. Deviation of Hardy-Weinbergs expectation was detected in the studied population using Wrights F statistic. The panel showed 30% variation among population and 70% among individuals. The entire population was categorized into three sub-populations through STRUCTURE analysis. This revealed tolerance for the trait had a common primary ancestor for each

I was recently re-reading the ca. 4th-century BC collection of advice and admonitions attributed to the Chinese philosopher Mencius. When I came across the following famous passage, parenthood made me see it in a new light:. You must not be like the man from Sung. There was a man from Sung who pulled at his seedlings because he was worried about their failure to grow. Having done so, he went on his way home, not realizing what he had done. I am worn out today, said he to his family. I have been helping the seedlings to grow. His son rushed out to take a look and there the seedlings were, all shrivelled up. There are few in the world who can resist the urge to help their seedlings grow. There are some who leave the seedlings unattended, thinking that nothing they can do will be of any use. They are the people who do not even bother to weed. There are others who help the seedlings grow. They are the people who pull at them. Not only do they fail to help them but they do the seedlings positive ...

A genetic program that in sunflower seeds is activated by Heat Shock transcription Factor A9 (HaHSFA9) has been analyzed in transgenic tobacco seedlings. The ectopic overexpression of the HSFA9 program protected photosynthetic membranes, which resisted extreme dehydration and oxidative stress conditions. In contrast, heat acclimation of seedlings induced thermotolerance but not resistance to the harsh stress conditions employed. The HSFA9 program was found to include the expression of plastidial small Heat Shock Proteins that accumulate only at lower abundance in heat-stressed vegetative organs. Photosystem II (PSII) maximum quantum yield was higher for transgenic seedlings than for non-transgenic seedlings, after either stress treatment. Furthermore, protection of both PSII and Photosystem I (PSI) membrane protein complexes was observed in the transgenic seedlings, leading to their survival after the stress treatments. It was also shown that the plastidial D1 protein, a labile component of the PSII
This year, because of rising input costs, more plug growers are focusing efforts on getting maximum yields from every plug tray. Buying good seed, sowing it accurately and providing good germination conditions are just half the battle. There is a considerable difference between germination and usable seedlings. Losing seedlings after germination is finished costs a lot more money! If you are having problems consistently with losing seedlings of certain crops, then you are doing something consistently wrong. However, if you lose seedlings every once in a while and dont understand why, then you need to look at the influences of your growing environment and culture on your techniques.. Plug growers around the country lose seedlings after germination for a number of reasons, including tip or leaf burn, tip abortion and stunted seedlings. These problems dont show up all the time, but they do rear their ugly heads every year. Understanding which crops are sensitive to these problems, when they are ...
Salt stress is one of the major abiotic stress which severely limits plant growth and reduces crop productivity across the world. In the present study, the effects of exogenous pyridoxal-5-phosphate (vitamin B6, VB6) on seedling growth and development of wheat under salt stress were investigated. The results showed that exogenous application of pyridoxal-5-phosphate (VB6) significantly increased the RWC, biomass, the concentration of photosynthetic pigments, proline, the activities of superoxide dismutase (SOD), catalase (CAT), peroxidase (POD), together with decreasing the content of Malondiadehyde (MDA) and hydrogen peroxide (H2O2) in wheat leaves under salt stress. Meanwhile, the transcript level of P5CR, P5CS, SOD, TaSOS1 and TaSOS4 were also up-regulated after treatment with pyridoxal-5-phosphate. VB6 acts as a signal in regulating the activities of plant antioxidant enzymes and SOS pathway to improve resistance to salt stress. The current study results may give an insight into the ...
Environmental projections using averaged climate data may be underestimating the potential for new trees to get established, says a new study in the journal Ecography, led by HF post-doctoral fellow Pep Serra-Diaz. . Tree seedlings pave the way for tree species to shift their ranges over time; they colonize new territories and ensure long-term population viability. Seedlings are also more sensitive to changing environmental conditions than mature trees. . Serra-Diazs team used microclimatic modeling and an experiment on seedling survival to investigate how well seedlings survive in shorter-term climate windows. Their results showed that potential new areas of tree establishment may be overlooked in environmental projections if climate conditions are averaged, as they often are, over decades.. They recommend that projections of forest species distributions seek to better incorporate the nuanced ways trees experience climate in different life stages. ...

Environmental stresses frequently affect plant growth and development, and many genes have been found to be induced by unfavorable environmental conditions. Here, we reported the biological functions of TaNAC2D, a stress-related NAC (NAM, ATAF, and CUC) gene from wheat. TaNAC2D showed transcriptional activator activity in yeast. TaNAC2D-GFP fusion protein was localized in the nucleus of wheat mesophyll protoplasts. TaNAC2D transcript abundance was significantly induced by NaCl, PEG6000, and abscisic acid (ABA) at seedling stage, and repressed by NaCl and PEG6000 at mature plant stage. When TaNAC2D was introduced into Arabidopsis, the 35-day-old soil-grown TaNAC2D-overexpression (TaNAC2D-OX) plants displayed slower stomatal closure, higher water loss rate, and more sensitivity to salt and drought stresses compared with WT plants. In contrast, TaNAC2D-OX seedlings, grown on 1/2 MS medium supplemented with different concentrations of NaCl, Mannitol, and MV, had enhanced tolerances to salt, osmotic and

It is natural for any seedling to grow and elongate looking for light. Get them hardened off before they stay outside or increase the power of your light. Just bringing the lamp down to the seedlings might be enough to increase the light and thicken your seedlings. Dont worry about genetics...all your seedlings will do fine when you get them in decent light. Just dont ever put in the sun a plant grown indoors, a greenhouse, a shady porch without hardening it off. Depends on the plant but basically you start with a few minutes the first day, a few more the next until it can stay out all day. Otherwise the sun can burn and kill plants not hardened off...careful with fertilizer with seedlings. Keep fertilizer to a bare minimum until the plant is out in decent lighting.. ...

While transplanting makes it easier to give your young plants access to plenty of water and air, it can stress the plants if not done right, and it can also be too much work for some growers. So many growers start their plant in its final container.. When seedlings or clones are started in a large container, it can be difficult to get enough air to the roots until the plant is bigger and drinking a lot. Thisis because when the potting mix gets soaked, the seedling roots just wont be able to drink it fast enough, and the roots will end up sitting in stagnant water with very little acces to oxygen. The growing medium has to dry out on its own, which can take a while, and your plant will be droopy and overwatered until the roots start getting access to air again.. Some growers start their seedlings or clones in a bigger pot, or even the final container they plan to use. While this can slow down growth of young seedlings, you can minimize this effect by watering young plants correctly when ...

Light signals are essential environmental cues for seedlings to elaborate their developmental program during the transition from heterotrophy to autotrophy. The effects of light on seedling development can be observed at many levels, including gene expression, cell differentiation, and plant morphology. During seedling development, higher plants, such as Arabidopsis, can adopt two contrasting development schemes: skotomorphogenesis, which takes place in the dark, and photomorphogenesis, which occurs in the light (Kendrick and Kronenberg, 1994). Dark-grown seedlings undergoing skotomorphogenesis exhibit etiolated morphologies, including long hypocotyls, apical hooks, and closed and undeveloped cotyledons. The genes required for chloroplast development and photosynthesis are expressed at low or undetectable levels. When exposed to light, seedlings undergo photomorphogenesis and exhibit deetiolated morphologies, such as short hypocotyls and open and developed cotyledons. Expression of genes ...

Rhynchosporium secalis can overcome a single resistance gene of barley in a relatively short period of time. Novel genes and quantitative trait locis (QTLs) are therefore vital to control scald in barley. A population of 220 double haploid lines was developed from a cross of Vlamingh and WABAR2147, where Vlamingh showed adult plant resistance (APR) and WABAR2147 showed seedling resistance to a group of isolates. The population was tested for APR to scald under natural infection in two consecutive seasons in addition to a seedling screen with three isolates. One single gene was mapped to chromosome 6H based on the seedling test, and two QTLs (QSc.VlWa.4H and QSc.VlWa.6H) were mapped to chromosomes 4H and 6H based on APR. Epistatic interaction was observed between the two QTLs, and environment/QTL interaction was only observed for QSc.VlWa.6H which co-segregated with the seedling resistance gene and contributed to basal resistance against scald during whole growth stages. QSc.VlWa.4H explained ...
1. Alpine and Arctic treeline expansion depends on establishment of tree seedlings beyond the current treeline, which is expected to occur with climate warming. However, treelines often fail to respond to higher temperatures, and it is therefore likely that other environmental factors are important for seedling establishment.. 2. We aimed to analyse our current understanding of how temperature and a range of other environmental drivers affect tree seedling establishment at the alpine and Arctic treelines world-wide and to assess the relative importance of temperature compared with other factors and how they interact.. 3. We collected 366 observations from 76 experimental and observational papers for a qualitative analysis of the role of a wide range of environmental factors on tree seed germination, tree seedling growth, survival and natural occurrence. For a subset of these studies, where the experimental design allowed, we conducted formal meta-analyses to reveal if there were global drivers ...

Weed plants need light throughout their life cycle, but during the seedling stage not really so much. And if you wonder how much light is ideal, we recommend to err on the side of caution. Its hardly the best option to keep your cannabis seedlings under HPS grow lights. Use weaker lights, instead, like CFLs, T5s, or LED lights. This will not only allow you to save on electricity, but spare your sprouts from shock. And if you insist on using HPS or other high intensity discharge (HID) lamps, raise them high, probably as high as your grow room allows. Still, under light of this type, seedlings can show signs of stress, slow down their growth, and demonstrate various worrying symptoms. In this case, though it may seem counterintuitive to you, youll see better results if you temporarily keep your weed in the window - until its mature enough to handle strong light.. Another question is when to put weed seedling under light. Some growers do it even before their sprouts emerge from the medium. ...
It may not seem like a huge difference when it comes to sending a seedling plant as a gift compared to sending a medium to large plant/tree but in reality there is quite a difference that you may or may not be aware of when it comes to choosing a living beautiful good quality gift to send someone. The size of a plant matters! The mortality rate of seedling plants is quite high, in the sense that they need extra love and care in its first stages of life to flourish. Compare this with a garden centre grade plant/tree of medium or large sized, some of the job has already been done and it is at a stage where it is much stronger to survive. Beneficial also to that of receiving a plant over a seedling plant is that it will become fully grown in a shorter amount of time and you can reap the rewards of some plants such as fruit bearing trees a lot quicker but still have the privilege of helping and watching it to grow. The mortality rate of seedling plants compared to that of a garden centre grade plant ...
We can measure the useful light to a plant (PAR - photosynthetically active radiation, or the parts of light that the plant can use to photosynthesize) in micromoles per meter square per second (micromoles/sec-m2) . The goal here is to deliver 120-150 micromoles/sec-m2 of PAR to your seedlings.. Some people will use a PAR meter to figure out how much PAR theyre getting to their seedlings, and will adjust the distance of their lights based on that measurement. Dont worry- you dont need one for this if youre using LED bars or fluorescent bars. Just remember the following distances.. LED bars (like Philips): 8-12 inches away from seedlings.. T5 fluorescents: 5-6 inches away from seedlings.. ...
It has been challenging to design seedling pick-up mechanism based on given key points and trajectories, because it involves dimensional synthesis and rod length optimization. In this paper, the dimensional synthesis of seedling pick-up mechanism with planetary gear train was studied based on the data of given key points and the trajectory of the endpoint of seedling pick-up mechanism. Given the positions and orientations requirements of the five key points, the study first conducted a dimensional synthesis of the linkage size and center of rotation. The next steps were to select a reasonable solution and optimize the data values based on the ideal seedling trajectory. The link motion was driven by the planetary gear train of the two-stage gear. Four pitch curves of noncircular gears were obtained by calculating and distributing the transmission ratio according to the data. For the pitch curve with two convex points, the tooth profile design method of incomplete noncircular gear was applied. The

No matter what medium is used for starting seeds, it should drain well and have a fairly low pH. Mixes with a pH of 6.4 or less are not as susceptible to damping off as those with a higher pH.. To prevent damping off, tap water should not be used on seedlings. Tap water can be alkaline in many cases and it will gradually increase the pH in the planting medium. Instead, use distilled water. If you know that your water is alkaline, you may also add a tablespoon of white vinegar to a gallon of filtered tap water and use that for watering your seedlings.. The planting medium should be kept moist but should never be soggy. Damping off fungi thrive in conditions that are too wet. Ideally, the medium should be watered from the bottom, rather than the top. To water from the bottom, simply place the flats or pots of seedlings in a shallow container of water until the planting medium has absorbed enough water to moisten it. Do not allow the flats or pots to remain in the water until the medium becomes ...

Not really. That would encourage the plants to get leggy. Long spindly stems. The same happens when seedlings are put in a window; they try to stretch up to the sun. Called heliotrophic. They also bend out toward the light. Florescent lights are cooler with full spectrum light and you put the bulbs within an inch of the top of the plant. It does not burn the leaves and makes the seedling stems compact and strong. A cheap shop light will do the trick so no need to buy an expensive lighting system. As the plants grow make it so the top of the plant is about an inch below the bulb. Mine are in a basement so I raise the light. But lowering the plant does the same thing ...

A quantitative and predictive measure of seedling vigor during the regeneration chain would be of utmost help for forest regeneration work. This was the impetus to study the possibility of using abscisic acid (ABA) concentration of Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) needles as an indicative measure of seedling vigor prior to outplanting. The experiment included two lifting times (mid-November, mid-January), two pretreatments (normal dormancy, fall photoperiod), and three cold storage treatments (dark, light, and bareroot). Needle samples were taken four times during the experiment: 1) after 48 hours in the cold room, 2) prior to taking seedlings out of the cold room after 25 days of storage, 3) 48 hours in the growing environment, and 4) at the time of bud break.

[Objective] The study aimed to discuss the regulation action of La3+ in rare earth on the antioxidant enzyme activity of winter wheat seedlings under low-temperature stress.[Method] With the winter wheat variety Yongliang 4 as the tested material,5 concn.grads of La3+ at 5,10,20,30 and 40 mg/kg were set up to spray the wheat seedlings.The test method of simulating the low temperature chilling injury was used to study the regulatory effects of La3+ on SOD,POD and CAT activities in the leaves of winter wheat seedlings.[Result] In the 7 d of La3+ treatment and in the treatment with low temperature at 0,5 and 10 ℃,SOD activity in winter wheat was increased remarkably with the decrease of temperature and showed a trend of first rising and then falling with the La3+ treatment days.CAT and POD activities also showed a trend of first rising and then falling with the decrease of stress temperature and the increase of La3+ treatment days.After the winter wheat was treated with La3+ at 20 mg/kg under low
Seedling establishment is one of the most important, yet stress-sensitive, stages in the plant life-cycle. Seedling quality is largely established during seed development and maturation as a result of often complex interactions between the genome and the environment. The molecular genetic dissection of these interactions will allow the identification of genes that control seed and seedling quality. These genes will be the starting point to unravel the signalling pathways in which they are involved and will reveal the regulatory processes that ultimately influence seed and seedling quality. In the here proposed project we will use a quantitative trait loci (QTL) approach to unlock the genetic variation for seedling quality that is present in tomato and Arabidopsis recombinant inbred line (RIL) populations grown under different environmental conditions. The classical QTL analysis will be combined with transcriptome, metabolome and hormone analysis of all lines in the population in a so called ...
We describe the results of four laboratory studies designed to measure the effect of temperature and wireworm appetence, weight, and degree of Metarhizium infection on their ability to damage wheat seedlings. Wireworm activity, measured from wireworm speed, increased linearly from 6 to 18 °C and leveled off thereafter. Plant emergence and growth increased exponentially from 6 to 22 °C for wheat cultivars AC Barrie and AC Unity VB. Plant root:shoot ratio at Zadoks 13 was highest at 14 °C and lowest at 22 °C for AC Barrie. Wireworm weight and degree of infection with Metarhizium did not affect their ability to kill wheat seedlings, but wireworms in a feeding state caused significantly more damage than those in a non-feeding state when wheat was grown at 10, 14, 18, and 22 °C. Wireworms (ww) in a feeding state destroyed 1.8 seedlings/ww in 14 days at 22 °C if there were 1 or 2 wireworms in a pot, and 1.5 seedlings/ww if there were 4 wireworms in a pot. If 5 wireworms were placed in a pot, ...

Three hundred and fifteen wild barley accessions from the Wild Barley Diversity Collection (WBDC) were evaluated for nine seedling vigor traits in a polyhouse and growth chamber under hydroponic conditions. The accessions exhibited significant differences for all traits investigated. Traits showing greatest phenotypic variation were seedling visual score, plant height, shoot fresh weight, shoot dry weight and shoot length. Seed weight exhibited the least variation. Seed weight was significantly correlated with visual ...

Field conditions vary widely across the Midwest right now and may put early planted corn at added risk for seedling diseases. In some areas cool soil temperatures and episodes of recent rainfall are especially favorable for some of the most common and damaging seedling diseases; in other areas, field conditions are quite dry. Numerous seedling diseases can occur and take advantage of any of these conditions. Be sure to monitor seedling emergence and stand establishment in the coming weeks so that if problems occur, they can be detected as early as possible.. Seedling diseases can be caused by any of several common soilborne organisms, such as Pythium, Fusarium, Rhizoctonia or plant parasitic nematodes. Seedling diseases are often difficult to diagnose because their symptoms are very similar. Sometimes diagnosis may be of limited value because management is the same for several seedling diseases. Microscopic examination and other laboratory analyses of the diseased seedlings often can identify ...
Discussion. Pythium myriotylum and P. volutum were identified as the most aggressive species causing root rot of tobacco seedlings. Pythium myriotylum has been previously reported as the principal species causing this disease (2,4,7). In our study P. volutum was the second most frequently observed species. This is the first report of this Pyhtium species affecting tobacco seedlings. P. dissotocum, P. irregulare, and P. spinosum were also isolated from seedlings that developed root discoloration, but these species did not significantly reduce the production of usable transplants. The pathogen was not recovered in a large percentage of seedlings with visual root discoloration. These last two findings suggest that (a) root discoloration may not a safe diagnostic symptom for Pythium root rot on tobacco seedlings and (b) some Pythium spp. may cause infection but no severe disease development and thus remain undetected. It was also rather unexpected that P. aphanidermatum, commonly found in tobacco ...
Where belowground resources are relatively abundant, naturally established trees sometimes occur in very close proximity to one another. We conducted a two-year study to assess the aboveground interactions between Douglas-fir (Pseudotsuga menziesii), grand fir (Abies grandis) and noble fir (Abies procera) seedlings planted in closely spaced (stems 10 cm apart) conspecific and heterospecific pairs. Paired seedling growth also was compared to seedlings planted with no neighbor. Stem height growth was not affected by the presence of a neighbor seedling, although diameter growth was slightly reduced. Branch diameter growth and weight were reduced where seedling crowns overlapped; branch morphological data suggested that this was caused by shading rather than mechanical interactions. Light measurements showed the potential for significant shading, particularly by the relatively large, dense crowns of Douglas-fir. Heterospecific pairs including Douglas-fir demonstrated the competitive production ...

To construct a model of seedling establishment from local sources, we used data from Guam on the identity and number of adult trees surrounding each gap (the raw data are provided in Dataset S1), coding each adult species as having a seedling established in the gap (1) or not (0). Seedling species presence or absence was then modeled assuming the outcomes were drawn from a Bernoulli distribution with a different probability (on the logit scale) for each species (reflecting differences among adult tree species in their probability of producing a seedling), each gap (reflecting differences among gaps in their favorability for establishment), and a slope term linked to the number of adult trees of each species surrounding a gap (assuming a greater number of trees of a given species would result in higher seed rain and greater probability of seedling establishment). Differences in establishment probability among species and among gaps were modeled hierarchically, treating these as random effects ...
1-0 seedlings of Douglas-fir from five physiographic regions in northern California and western Oregon were lifted monthly in winter in Humboldt Nursery, stored at 1° C, and planted in spring in the region of seed origin. Field survival indicated that the calendar periods for safe lifting span 2 or 3 months, and closely match those determined for 2-0 seedlings of similar sources in earlier trials. After one summer, survival of 1-0 seedlings was 90 percent in the southern Klamath Mountains, 94 and 99 percent in the King and Oregon Coast Ranges, and 84 and 88 percent in the Eastern Siskiyou Mountains and Oregon Cascade Range. Browsing mammals and competing vegetation reduced seedling survival and growth. Mortality the second summer ranged from 3 percent in the Coast Range to 17 percent in the Eastern Siskiyous. Increase in height ranged from zero in the Klamath Mountains to about fourfold in the Coast Range. With protection, successful plantation establishment with 1-0 Douglas-fir is attainable in all
Abiotic stress is a term to describe a complex syndrome of effects of various environmental stress factors (e.g. temperature, water availability, salt, heavy metals, pesticides, UV) if they severely deviate from a normal or optimal (non-stress) situation. The overall aim of the project is to generate knowledge and establish tools required to make the most vulnerable stages of the sugar beet life cycle, namely germination and emerged seedlings, more resilient towards abiotic stresses. Due to erratic weather and climate change in temperate growing regions an increase the abiotic stress tolerance during early season stages requires a strategic focus on germination and seedling responses to improve seed quality ...
Northern red oak (Quercus rubra) seedlings were placed in three grades based on number of first-order-lateral roots. The grades were poor, medium, and good and had numbers of 0 to 6, 7 to 11, 12, and > 12, respectively. Eighty seedlings from each group were either underplanted or established in an adjacent clearcut on a high-quality mesic site in North Carolina. There were 240 seedlings outplanted on each area. The poor-graded seedlings were initially smaller than the medium and good seedlings with heights and root collar diameters of about 67 centimeters and 7.4 millimeters; 115 centimeters and 11.3 millimeters; and 138 centimeters and 13.4 millimeters, respectively. Survival was better overall with the underplanted seedlings at year 7, with the poor, medium, and good seedlings surviving at 75, 78, and 96 percent, respectively. Growth was unsatisfactory for all three grades. Survival on the clearcut was affected by a 17-year-locust (Magicicada septendecim L.) infestation and heavy stump sprout ...
A greenhouse research was conducted at the research area of Department of Plant Breeding and Genetics, University of Agriculture, Faisalabad to evaluate 20 accessions for the identification of salt tolerant genotypes of sunflower (Helianthus annuus L.) as well as their characteristics. The experiment was conducted in completely randomized design with three repeats. Salinity was developed with NaCl to achieve the final levels of 3, 6 and 9 dsm-1 salinity, whereas control contained tap water. After 60 days of planting, 10 seedlings of each accession from each treatment and replication were uprooted and data was recorded. Sunflower genotypes G-36, G-61, A-23, A-61 and A-185 performed better in both controlled and saline conditions. These genotypes showed better shoot and root growth and biomass by least concentration of Na+ and higher concentration of Cl- in leaf sap.   Key words: Tap water, NaCl, replication, leaf sap.

The effect of defoliation and consecutive defoliation (condefoliation) of rye seedlings on the allocation patterns of biomass and hydroxamic acids (Hx) was evaluated five days after treatment. Growth of condefoliated seedlings was lower than that of defoliated and nondefoliated ones. Concentration of Hx decreased in shoots of condefoliated seedlings compared to nondefoliated ones, while concentration of Hx in root exudates increased. Allocation of Hx to roots and root exudates increased at the expense of allocation to the shoots in condefoliated seedlings. The ratio of Hx-aglucone to Hx-glucoside was higher in shoots of defoliated and condefoliated seedlings. The decrease in quantity of defense in shoots was accompanied by an increase in its quality, given that aglucones are more toxic than glucosides. The increase in concentration of Hx-an allelopathic compound also involved in mineral uptake by roots-in root exudates of condefoliated seedlings was suggested to lead to an advantage in the acquisition
Seedling root traits of wheat (Triticum aestivum L.) have been shown to be important for efficient establishment and linked to mature plant traits such as height and yield. A root phenotyping pipeline, consisting of a germination paper-based screen combined with image segmentation and analysis software, was developed and used to characterize seedling traits in 94 doubled haploid progeny derived from a cross between the winter wheat cultivars Rialto and Savannah. Field experiments were conducted to measure mature plant height, grain yield, and nitrogen (N) uptake in three sites over 2 years. In total, 29 quantitative trait loci (QTLs) for seedling root traits were identified. Two QTLs for grain yield and N uptake co-localize with root QTLs on chromosomes 2B and 7D, respectively. Of the 29 root QTLs identified, 11 were found to co-localize on 6D, with four of these achieving highly significant logarithm of odds scores (,20). These results suggest the presence of a major-effect gene regulating ...
Phosphate starvation compromises electron flow through the cytochrome pathway of the mitochondrial electron transport chain, and plants commonly respond to phosphate deprivation by increasing flow through the alternative oxidase (AOX). To test whether this response is linked to the increase in nitric oxide (NO) production that also increases under phosphate starvation, Arabidopsis thaliana seedlings were grown for 15 d on media containing either 0 or 1mM inorganic phosphate. The effects of the phosphate supply on growth, the production of NO, respiration, the AOX level and the production of superoxide were compared for wild-type (WT) seedlings and the nitrate reductase double mutant nia. Phosphate deprivation increased NO production in WT roots, and the AOX level and the capacity of the alternative pathway to consume electrons in WT seedlings; whereas the same treatment failed to stimulate NO production and AOX expression in the nia mutant, and the plants had an altered growth phenotype. The NO donor S
Results: We studied the response of transgenic seedlings of Arabidopsis thaliana, containing either the CycB1-GUS proliferation marker or the DR5-GUS auxin-mediated growth marker, to diamagnetic levitation in the bore of a superconducting solenoid magnet. As a control, a second set of seedlings were exposed to a strong magnetic field, but not to levitation forces. A third set was exposed to a strong field and simulated hypergravity (2 g). Cell proliferation and cell growth cytological parameters were measured for each set of seedlings. Nucleolin immunodetection was used as a marker of cell growth. Collectively, the data indicate that these two fundamental cellular processes are decoupled in root meristems, as in microgravity: cell proliferation was enhanced whereas cell growth markers were depleted. These results also demonstrated delocalisation of auxin signalling in the root tip despite the fact that levitation of the seedling as a whole does not prevent the sedimentation of statoliths in the ...

When we first moved onto acreage, we were in the great rolling hills northeast of Colorado Springs. Our property was not treed and the only growth to speak of was weeds. Now in our second home on acreage, we looked into a seedling program offered by the state. Crazy as it is, I recall doing this when my family moved to Castle Rock, CO in 1988. We planted a huge tree line and now the trees are beautiful and tall. Well, the state of Colorado seedling program is great!

Radish (Raphanus sativus L. var. Redondo Vermelho) seedlings were analyzed by light and scanning electron microscopy to characterize the anatomical and morphological changes caused by the exposure to 0.5 or 1.0 mM CdCl2 for 24, 48 and 72 h. The analyses showed changes in the anatomical and morphological characteristics of roots, stems and leaves of two-week-old seedlings. In all tissues, loss of cell turgidity was observed. Premature death with disintegration of the epidermis and an increase in number of root hairs were observed in roots exposed to the heavy metal. The stems of seedlings exposed to cadmium exhibited an increased number of cells in the cambial layer. The main effects observed in leaves were stomatal closure, increase in chloroplast size and number, followed by a decrease in number of chloroplasts in response to the metal toxicity. This study suggests that the anatomical and morphological changes observed in seedlings treated with CdCl2 were mainly caused by a decrease in water ...

I transplant the seedlings at this point into the 4x6 plastic flats used by nursery men for bedding plants. The seedlings are planted on 1 centers in rows one inch apart using a mixture of fine leaf mold and peat. This mixture is porous and the small seedlings seem to start out fast. The little plants are watered in when they are planted and the flats are covered for one or two days to avoid shock. Again, Captan is used if needed. After one to two months, the seedlings are transplanted again into regular cedar flats on two or 2½ centers in rows 2 to 2½ apart. I use the same mixture of leaf mold and peat moss, watering the plants in and at this time using Millers Booster Powder either added to the soil mixture or in the water used to water the plants in. I try to get the flats into a lath house quite early, to get the largest plants possible by fall as the larger the plants the better the chances of them surviving their first winter. During the winter, one should watch the drainage in these ...
The effect of three moisture levels and three shade regimes on the growth of D x P ex Kusi oil palm seedlings was investigated at the Oil Palm Research Institute, Kusi between July 1998 and February 2000 in a factorial experiment laid out in randomized complete block design with four replications. The moisture treatments investigated were W1 (50-60 % field capacity), W2 (65-75 % field capacity) and W3 (80-90 % field capacity). The shade treatments investigated were S1 (0 % shade), S2 (50 % shade) and S3 (75 % shade). Data was collected on leaf number per plant, plant height, butt circumference and leaf area as well as dry weight of plant parts and total dry matter. There were significant effects due to shade and shade x moisture interactions on seedling growth. Seedlings under 50% shade (50% full sunlight) in combination with low moisture supply (50-60% field capacity) were comparable in growth to those under 0% shade (100% full sunlight) with high moisture supply (80-90% field capacity).

The goal of this research is to develop automatic techniques for identifying defects in Douglas-fir veneer. To achieve this goal, computer vision techniques, in particular image-processing, will be applied. Several pre-processing steps may be required to enhance images in making further analysis easier, faster, and more reliable. Pre-processing is often necessary when analyzing natural materials due to the amount of complex variation present. However, if such analysis is associated with several compute-intensive passes over a large data set, the possibilities of what can be achieved, is very limited. It is advantageous to reduce the data in a way that little or no information is lost that may affect the image analysis. This reduced image is then used in subsequent analysis to determine the actual type of defect, its extent and exact location. Whether such a reduction is possible usually depends on the intended application. For Douglas-fir veneer sheets at the plugging stage, the material is ...
In dicot Arabidopsis thaliana embryos two cotyledons develop largely autonomously from the shoot apical meristem (SAM). Recessive mutations in the Arabidopsis receptor-like kinase RPK1 lead to monocotyledonous seedlings, with low (10 %) penetrance due to complex functional redundancy. In strong rpk1 alleles, about 10 % of these (i. e. 1 % of all homozygotes) did not develop a SAM. We wondered whether RPK1 might also control SAM gene expression and SAM generation in addition to its known stochastic impact on cell division and PINFORMED1 (PIN1) polarity in the epidermis. SAM-less seedlings developed a simple morphology with a straight and continuous hypocotyl-cotyledon structure lacking a recognizable epicotyl. According to rpk1s auxin-related PIN1 defect, the seedlings displayed defects in the vascular tissue. Surprisingly, SAM-less seedlings variably expressed essential SAM specific genes along the hypocotyl-cotyledon structure up into the cotyledon lamina. Few were even capable of developing an

Powders from germinated seedlings of wheat, barley, rapeseed, maize, and linola synthesized low molecular weight flavor esters in an organic medium (hexane). Direct esterification of acetic, butyric, and caproic acids, with ethanol, butanol, isopentanol, or (Z)-3- hexen-l-ol was achieved. Of the systems examined, germinated rapeseed showed the highest degree of flavor synthesis. (Z)-3-hexen-1-yl butyrate and (Z)-3-hexen-1-yl caproate were produced with yields of about 96%. Butyl butyrate, isopentyl butyrate, butyl caproate and isopentyl caproate were produced at 80% yield. Linola seedling powder gave yields of ≤63% for ethyl acetate and butyl acetate. More moderate (40%) yields were obtained with barley and maize seedling powders. Rapeseed seedling powder is a convenient and inexpensive catalyst for preparing low molecular weight esters in organic media. ...

Interpretive Summary: Volatile organic compounds (VOCs) produced by Plant Growth Promoting Rhizobacteria (PGPR) have recently been investigated due to their role in plant growth promotion and defense. Whereas some bacterial VOCs produced by strains of Bacillus subtilis and Bacillus amyloliquefaciens promote plant growth, other compounds inhibit plant growth or are phytotoxic. Bacillus mojavensis, a close relative of B. subtilis, is an endophytic bacterium of maize that has been shown to have antagonistic activity against the mycotoxigenic phytopathogen Fusarium verticillioides and growth promotion activity on maize seedlings. To investigate the growth promotion activity of B. mojavensis, Arabidopsis thaliana seedlings were grown on 1/2x Murashige & Skoog (MS) medium in divided Petri dishes while bacteria were grown either on 1/2x MS or nutrient agar (NA) medium, so that microbial volatiles reach the seedlings without other contact. Significant plant growth promotion in A. thaliana seedlings was ...

Like most species of Annona, it requires a tropical or subtropical climate with summer temperatures from 25 °C (77 °F) to 41 °C (106 °F), and mean winter temperatures above 15 °C (59 °F). It is sensitive to cold and frost, being defoliated below 10 °C (50 °F) and killed by temperatures of a couple of degrees below freezing. It is only moderately drought-tolerant, requiring at least 700 mm of annual rainfall, and will not produce fruit well during droughts. It will grow from sea level to 2,000 metres (6,600 ft) and does well in hot dry climates, differing in its tolerance of lowland tropics from many of the other fruit bearers in the Annona family. It is quite a prolific bearer, and it will produce fruit in as little as two to three years. A five-year-old tree can produce as many as 50 sugar apples. Poor fruit production has been reported in Florida because there are few natural pollinators (honeybees have a difficult time penetrating the tightly closed female flowers); however, hand ...

The origin of the lemon is unknown, though lemons are thought to have first grown in Assam (a region in northeast India), northern Burma or China.[2] A genomic study of the lemon indicated it was a hybrid between bitter orange (sour orange) and citron.[3][4] Lemons entered Europe near southern Italy no later than the second century AD, during the time of Ancient Rome.[2] However, they were not widely cultivated. They were later introduced to Persia and then to Iraq and Egypt around 700 AD.[2] The lemon was first recorded in literature in a 10th-century Arabic treatise on farming, and was also used as an ornamental plant in early Islamic gardens.[2] It was distributed widely throughout the Arab world and the Mediterranean region between 1000 and 1150.[2] The first substantial cultivation of lemons in Europe began in Genoa in the middle of the 15th century. The lemon was later introduced to the Americas in 1493 when Christopher Columbus brought lemon seeds to Hispaniola on his voyages. Spanish ...
