Higher plants generate physiological active substances termed phyto-hormones. These natural phyto-regulators are synthesized by the plant itself and act in a location distant from the source of production. There are several phyto-hormone groups, the best known is the auxin group.In plants, phyto-hormones control the intensity of metabolism, the production of other phyto-hormones, production and decomposition of pigments, displacement of certain substances into certain organs or storage in them, elongation of the cell wall, the development of flowers, and also growth and growth rate (with absence of individual hormones leading to dwarfing and inhibition of development).Auxins occur in all plants, most importantly indole-3-acetic acid. Many plants also contain indole-3-aceticaldehyde, indole-3-butyric acid, indole-3-acetonitrile and indole metabolic derivatives such as 2-hydroxyindole-3-acetic acid and ethyl indole-3-acetate with similar cell elongation action.The principle auxin in higher plants is Indole-3-Acetic Acid (IAA). This natural auxin is synthesized by the plant itself from the amino acity tryptophan. Auxins also help the plant heal itself, it controls the plants ability to grow or bend towards the light, aids in even or unified fruit development, and helps the plant produce ethylene, which helps in the ripening process. There are several other naturally occurring auxins in higher plants, although IAA is by far the most important.Physiological Effects of IAAIn high concentrations inhibition, in small concentrations promotion of longitudinal cell growth and the related water absorption of the cells. IAA causes a fairly rapid increase in the cell wall extensibility in coleoptiles and young stems.Promotion of cell division of the meristematic tissue.Promotion of root formation even on tissues which do normally form roots, but inhibition of growth, except in smallest concentrations.Promotion of callus formation and callus.Inhibition of budding and growth of auxiliary buds and bud formation.Influencing of leaf, flower and fruit shedding.Influencing of flower formationFormation of parthenocarpic fruit (seedless fruit).Promotion of respiration and protein formation.The optimal tissue auxin concentrationsFor elongation growth is typically 10-5 to 10-6 parts per millionFor root growth 10-10 parts per millionFor bud growth 10-8 parts per millionFor flower promotion 10-4 parts per millionThere are other classes of synthetic auxin analogs. These compounds, such as alpha-(p-chlorophenoxy) isobutyric acid or PCIB, have little or no auxin activity but specifically inhibit the effects of auxin, also know as anti-auxins.When Exogenous IAA is applied to plants, anti-auxins may compete with IAA for specific receptors, thus inhibiting normal auxin action. This inhibition can be overcome by adding Exogenous IAA. When shopping, please pay attention to the size and dimensions of the product to ensure that it meets your needs.
