Sie eignen sich auch sehr gut für Hydrokultur. Auswirkung auf das ...
Propagation. Commercially, most named self-heading Philodendron plants are propagated via tissue culture. Philodendron scandens oxycardium is normally propagated using 1-1½ inch stem cuttings with a node and an attached leaf. Buds break in 3-5 weeks and rooting occurs in 4-6 weeks. If larger leafed cuttings are desired for totems, stock plants are grown on a pole or similar support and tip cuttings are used. The tree philodendrons, P. bipinnatifidum and P. selloum, and some of the self-heading philodendrons may be propagated using commercially packaged seed. Viability is very limited unless the seed is properly processed and vacuum-packed. Successful seed germination and early seedling growth require specially equipped facilities, and most plant finishers buy seedlings from propagation specialists. Production. Sphagnum peat, pine bark, vermiculite, or perlite can be volumetrically combined to formulate media for most container sizes. Three-foot and taller totems should have 10-20% coarse sand ...

While they have a reputation as great easy-to-grow houseplants, can philodendron plants grow outdoors? Why yes, they can! So lets learn more about how to care for philodendrons outside! Click this article for additional information.
Split-leaf philodendron (Philodendron bipinnatifidum), also called cut-leaf or tree philodendron, is a tough shrub that will grow outdoors in some parts of the U.S. despite coming from the tropical rainforests of Paraguay and Brazil.
Philodendron Fungus. More than 200 species of philodendron (Philodendron spp.) can be found throughout Central and South America and the Caribbean islands. In the U.S., they are grown mostly as ornamental houseplants, though they can be grown outside in U.S. Department of Agriculture hardiness zones 10 through 11. Two ...
Ive been lugging a tree philodendron in and out of the house for so many years, I can no longer remember where it came from. As a houseplant, it has an adaptable soul, surviving all manner of abuse and neglect. If it didnt weigh so much, I think Id appreciate it more. Tree philodendron (P. bipinnatifidum, but until recently known as P. selloum) is native to southern Brazil and adjacent areas of Argentina, Bolivia and Paraguay. In its native habit, it often grows along rivers at the edge of the tropical forest. Plants develop a single, unbranched, 4-inch diameter trunk supported by long, dangling rope-like roots that restrict as the plant grows to provide tight anchorage. Stems can reach 8 feet or more in height. In nature, these tall stems eventually snuggle up to a tree trunk and the aerial roots anchor themselves to the bark, permitting the ongoing quest for light. The enormous leaves are the real attraction for the plant. Mine has leaves 30 inches long and 24 inches wide, each half of the ...

K. Steinkamp, C.A. Conover and A.R. Chase* Foliage plant producers most often use urea (CO(NH2)2), ammonium (NH4) or nitrate (NO3), alone or in various combinations to supply crop nitrogen (N) requirements. Determination of best N form for foliage plant production should be made after weighing several factors including cost, availability, plant response under various environmental conditions and ground water pollution potential. A number of experiments have been conducted at CFREC-Apopka to provide growers with information useful in making these fertilizer decisions.. Plant Growth and Quality Ideally, the most important factor deciding choice of N form should be plant growth response. In one experiment, seven fertilizers containing different forms of N were used to grow schefflera (Brassaia actinophylla), peacock plant (Calathea makoyana) and philodendron (Philodendron selloum) for nine months (Conover and Poole, 1982). Fertilizer formulations and percentages of nitrogen derived from NO3, NH4 ...

Flowers are the expression of the love life of plants," Tasker wrote of his photographs, as former curator and art historian Bonnie Yochelson recounts in her introduction to a monograph of his images. The poetry and beauty he saw in botany is evident in his minimal compositions: dark and diaphanous, each plant Tasker photographed stretches the length of the surface of each print. All parts are illuminated and completely exposed: we can clearly see the layers of petals that form the cup of a tulip and the carpels usually concealed in a lilys bell, now gossamer as if lightly sketched. In one radiograph, a philodendron rises tall, curving like the flame of a candle; in another, Tasker has captured a lotus from above so its petals splay like a gaping eye, with an iris surrounded by eyelashes of filaments.. There is nothing difficult about taking such images, Tasker apparently noted, with the only requirements being "an abiding patience" and a knowledge of "flowers and their habits." Still, he ...

Other dangerous types of plants? Cardiac glycosides like foxglove, lily of the valley, kalanchoe, Japanese yew, etc. Most of these grow outside, but when in doubt, Id keep these out of reach. This type does not cause kidney failure, but can cause life-threatening heart arrhythmias and death when ingested by dogs or cats.. Another common houseplant that cats seen to chew on are Dieffenbachia or philodendron. These plants contain insoluble calcium oxalate (not soluble calcium oxalate, like so many websites erroneously mention!), which cause oral pain when chewed on. This isnt life-threatening however, and typically just results in foaming and frothing at the mouth. My advice? Keep these plants elevated out of reach, and if your cat does get into it, just offer something tasty to flush out the mouth - a small amount of chicken broth, canned tuna water (not oil!), or even chicken noodle soup. If your cat continues to vomit, a veterinary visit is a must.. My hint? I keep one spider plant in my ...

Trees 60 to 100 feet tall make up the canopy layer of a rainforest. This layer is in full to partial sun and protected from winds by its density. Trees of the canopy are densely packed, forming a protected environment with full and partial sun. Lianas are a climbing vine up to 3,000 feet long that wrap around the trees of the canopy in an effort to reach the sun. They have sucker roots that allow them to attach to trees. The stems are woody and are so dense that they provide extra support for the shallow-rooted trees. Other plants, like the tree philodendron, start growing high in the treetops and send roots down to the ground. The roots can be over 90 feet long.. ...
When we moved to Texas a year ago, I had to leave all my houseplants behind. (I had years of history with those plants. A couple were gifts from people dear to me. It was very sad). So last August or September, I set out to find new ones. I was excited, thinking that because theres so much more sun in Texas, there would be significantly better houseplant options. Not so. Apparently, they dont really "do" houseplants down here. At least not in the Austin area and surrounds. (I miss Molbaks so bad, I can taste it). Pretty much, all you can find are asparagus ferns, philodendron (seriously? like you even NEED sun for those) and lucky bamboo. If you look, you can find some cool bromeliads. If looking turns into a year round habit, you can see a few other plants here and there, tucked in corners of shops on occasion. I finally found a prayer plant this month. Im ecstatic. So in the end, a year ago, I settled for a jade plant from IKEA that came with bugs and totally died, an incredibly groovy ...
Topiaries -- decorative shapes fashioned out of plants -- spark the imagination and add an interesting accent to any indoor garden. Formal hearts, hoops, spirals and cones are common shapes, as well as animals like swans, rabbits and elephants. Keep a few tricks of the topiary trade in mind, and you can create a work of art that will become your indoor garden focal point. When the wire shape is complete, choose a pot that will accommodate the base of the frame and insert into the soil. Other good topiary plants include hoya, creeping fig (Ficus pumila), rosemary and, for bigger topiaries, heart-leafed philodendron, pothos, grape ivy (Cissus rhombifolia) and wandering Jew (tradescantia sp.). Keep in mind that some topiary plants, such as creeping fig, require a sphagnum moss-filled frame. If the plant youve chosen already has some growth, wind it around the topiary frame, securing with green garden tape, hairpins or greening pins (found at the florist).

Karyotype analysis and FISH mapping using 45S rDNA sequences on 6 economically important plant species Anthurium andraeanum Linden ex André, 1877, Monstera deliciosa Liebmann, 1849, Philodendron scandens Koch & Sello, 1853, Spathiphyllum wallisii Regel, 1877, Syngonium auritum (Linnaeus, 1759) Schott, 1829 and Zantedeschia elliottiana (Knight, 1890) Engler, 1915 within the monocotyledonous family Araceae (aroids) were performed. Chromosome numbers varied between 2n=2x=24 and 2n=2x=60 and the chromosome length varied between 15.77 µm and 1.87 µm. No correlation between chromosome numbers and genome sizes was observed for the studied genera. The chromosome formulas contained only metacentric and submetacentric chromosomes, except for Philodendron scandens in which also telocentric and subtelocentric chromosomes were observed. The highest degree of compaction was calculated for Spathiphyllum wallisii (66.49Mbp/µm). B-chromosome-like structures were observed in Anthurium andraeanum. Their measured
Monocots, or monocotyledons, are a class of the flowering plants, or angiosperms. Monocots are named for and recognized by the single cotyledon , or seed leaf, within the seed. The first green blade emerging from the seed upon germination is the cotyledon, which contains sugars and other nutrients for growth until the leaf is able to photosynthesize. Monocots comprise about 67,000 species, or one-quarter of all flowering plants. They include not only the very large grass family (Poaceae, 9,000 species), but also the orchid family (Orchidaceae, 20,000 species), and the sedge family (Cyperaceae, 5,000 species), as well as palms, lilies, bromeliads (including pineapple), and the Araceae, which includes skunk cabbage and philodendron. The angiosperms have traditionally been divided into monocots and dicots alone, but recent work has shown that while monocots form a natural evolutionary group, dicots do not, and so the angiosperms are now grouped into monocots, eudicots , and basal angiosperms. In ...

What is exceptional is that the male cones possess a few sterile ovules and nectar, which indicates a failed attempt to invent the bisexual flower. Yet, in this plant (as well as in certain conifers), the researchers found genes similar to those responsible for the formation of flowers, and which are organized according to the same hierarchy (with the activation of one gene activating the next gene, and so on)!. The fact that a similar gene cascade has been found in flowering plants and their gymnosperm cousins indicates that this is inherited from their common ancestor. This mechanism did not have to be invented at the time of the origins of the flower: it was simply inherited and reused by the plant, a process that is often at work in evolution.. The study of the current biodiversity of plants thus enables us to go back in time and gradually sketch the genetic portrait of the common ancestor of a large proportion of modern-day flowers. The team is continuing to study other traits to better ...

THIS YEARS NOBEL Prize in Medicine went to three geneticists, Ed Lewis, Christiane Nüsslein-Volhard, and Eric Wieschaus, for their efforts to elucidate the mechanisms that pattern the body during development. This award also recognizes the contributions of geneticists over the past 150 years or so, which have led to some of the most remarkable findings of modern biology.. Early interest in the development of body pattern was largely motivated by curiosity on the origin of the diversity of living species. In 1859, Charles Darwin noticed a common feature of many creatures: repetition of elements along the length of the body, a property now known as segmentation. He remarked that nature had adapted some primordial, similar elements (segments) to diverse functions. Some years later, in 1894, William Bateson defined a phenomenon he named homeosis, by which one segment is transformed into the likeness of another. By the first quarter of this century, the father of modern genetics, Columbias Thomas ...
