It therefore follows that if you can control root growth in spring you can decrease the vegetative vigour of shoots, and hence increase fruit growth, especially on young fruit trees. (goodfruit.com)

The end of the initial peak in root growth usually corresponds with the beginning of active shoot growth. (goodfruit.com)
After harvest in autumn or cessation of shoot growth, root growth starts again, but is not as strong as in early spring. (goodfruit.com)
Clover species live together with root inhabiting bacteria that remove nitrogen from the air and make it available to the plants. (emnz.com)
This occurs through outcompeting negative and disease inducing microbial species and also by antagonistic activities against soil borne plant root pathogens. (emnz.com)
19. Accumulation of auxin on the lower side of the root accounts for the ………………… curvature. (icseboards.com)
Shoot and Root growth. (agrilearner.com)
Thus ultimately all shoot apices are in communication through their export of auxin into shared auxin transport paths to the root. (ens-lyon.fr)

Many animal hormones may exert their effects by influencing protein synthesis , and evidence suggests that auxins may act in a similar way. (britannica.com)

This promotes shoot growth, and restricts lateral branching. (wikipedia.org)
High-frequency shoot regeneration is one of the main aims of in vitro culture and it is a prerequisite to guarantee the success in transformation studies and in clonal propagation of plants. (intechopen.com)
All active shoot apices export auxin into the polar auxin transport stream, which transports it rootward. (ens-lyon.fr)

1989). Genetic transformation may enable the development of transgenic plants with enhanced resistance to wilt diseases. (scialert.net)

Structural variation in plant genomes is a significant driver of phenotypic variability in traits important for the domestication and productivity of crop species. (nature.com)
The number of plants of this species is continuously decreasing in nature because of cutting the plants and removing underground organs. (ejbiotechnology.info)
are plant growth promoting bacteria (PGPB) that increase grain yield in cereals and other species via growth promotion and/or stress alleviation. (conicet.gov.ar)
To analyze the regulatory mechanism involved in the high growth potential of C. virgata , we performed RNA-seq-based transcriptome analysis and illustrated a comprehensive gene expression map of the species. (frontiersin.org)
Bamboo plants that belong to the Poaceae family, which contains more than 1500 species, have been exploited for a range of uses, such as food, medicine, charcoal products, and housing materials, especially in Asia [1] [2]. (scirp.org)
It is the major source of nitrogen and improves pasture quality while also balancing the seasonal growth of grass species. (emnz.com)

The primary objectives of mine land reclamation are to minimize environmental degradation and to facilitate the reestablishment of a functional plant-soil system. (cdc.gov)

Moreover, strict regulatory policies and long approval process can further impede the market growth over the next few years. (techsciresearch.com)

this feature is of great value in research and in horticulture , because auxin action can be prolonged. (britannica.com)

The first naturally occurring cytokinin was isolated and crystallised simultaneously by Miller and D.S. Lethum (1963-65) from the milky endosperm of corn (Zea mays) and named Zeatin. (wikipedia.org)
Any of the hormones produced naturally in plants and active in controlling growth and other functions. (childrensmercy.org)

Therefore, the next important consideration is to obtain "clean" plants whenever possible, as well as selecting site-suitable cultivars and rootstock with resistance to A . vitis . (msu.edu)

The Power of Movement in Plants " marks the beginning of the modern study of plant growth", including signals and growth stimuli, later shown to be plant hormones. (tamu.edu)

It is well known that bamboo presents unique biological properties in its vegetative growth. (scirp.org)
In a fruit tree, the yield of fruit results from a balance between vegetative growth and associated fruiting. (goodfruit.com)
Economics force us to consider how and to what degree those resources need to be distributed toward vegetative or reproductive growth, both in the current season and in the long term. (goodfruit.com)
With any combination of scion and rootstock, vegetative and reproductive growth are genetically balanced. (goodfruit.com)
and to reduce vegetative growth and the need for pruning in trees. (slimtheme.com)

Also in context of biological control of plant diseases cytokinins seem to have potential functions. (wikipedia.org)
Although the chemical and physical properties of mine soils and wastes are important in determining initial plant establishment and growth, biological factors are essential for the successful maintenance of soil fertility and the evolution of a stable plant system. (cdc.gov)
These lights are used to simulate natural daylight and promote growth and development in animals, regulate their biological rhythms, and improve their overall health and productivity. (thebusinessresearchcompany.com)

the geotropic response occurs because more auxin accumulates along the lower side of the coleoptile than along the upper side. (britannica.com)
