introduction the plant hormones such as salicylic acid and gibberellin can affect the quantity and quality of crops. external application of plant growth regulators as a strategy for improving salt tolerance in plants is discussed. foreign salicylic acid can regulate antioxidant enzyme activity and increase plant resistance to abiotic stresses. salicylic acid reduction due to ethylene through t...

Intrauterine growth restriction (IUGR) impairs insulin secretion in humans and in animal models of IUGR. Several underlying mechanisms have been implicated, including decreased expression of molecular regulators of β-cell mass and function, in some cases shown to be due to epigenetic changes initiated by an adverse fetal environment. Alterations in cell cycle progression contribute to loss of β...

background & aim: recent researches have been done on effects of plant growth regulators (pgr) on growth and production of different crops whose results indicate the effectiveness of most of these hormones on qualitative and quantitative growth of herbs. the application of regulators and inhibitors of growth on herbs may, in addition to growth, also lead to secondary metabolites stimulation...

Measures for the introduction of organic agriculture, along with use appropriate techniques in imply rejection chemical-synthetic growth regulators or hormones; limited, strictly tied to area, livestock; feeding animals, if possible, their own feed, minimum purchase feed and avoiding antibiotics. However, there is currently no way permanently stop using Therefore, a gradual decrease doses, freq...

We describe a method for the simulation of the growth of elongated plant organs, such as seedling roots. By combining a midline representation of the organ on a tissue scale and a vertex-based representation on the cell scale, we obtain a multiscale method, which is able to both simulate organ growth and incorporate cell-scale processes. Equations for the evolution of the midline are obtained, ...

Biomass from cocoa plantations, such as rind, pulp, pruning of plants, and shade can be processed into animal feed, forage, extracts growth regulators, biochar. Goat manure solid liquid fertilizer. The purpose this paper is to obtain some bio-industry that may carried out by farmers who integrate farming with goats, additional income obtained, other benefits the integration. results analysis go...

Plasticity in plant form is achieved through differential elaboration of developmental pre-patterns during postembryonic organ development. A new report links the output of the root clock, an oscillatory transcriptional pre-patterning mechanism, with cell-type-specific production of the plant hormone auxin, and identifies a downstream component required for elaboration of the pre-pattern.

For survival, plants have to efficiently adjust their phenotype to environmental challenges, finely coordinating their responses to balance growth and defence. Such phenotypic plasticity can be modulated by their associated microbiota. The widespread mycorrhizal symbioses modify plant responses to external stimuli, generally improving the resilience of the symbiotic system to environmental stre...

During their evolution, plants have acquired diverse capabilities to sense their environment and modify their growth and development as required. The versatile utilization of solar radiation for photosynthesis as well as a signal to coordinate developmental responses to the environment is an excellent example of such a capability. Specific light quality inputs are converted to developmental out...
