Function characteristics: Gibberellin is one of the important endogenous hormones to promote plant growth and development.In plants, gibberellic acid is synthesized in the germination of seeds, buds, growing leaves, blooming flowers, stamens, pollen grains, fruits, and roots.The root composition moves up, while the top composition moves down, and the transport site is in phloem, and the transport speed is similar to that of photosynthetic products.Artificially produced gibberellic acid is absorbed mainly through leaves, twigs, flowers, seeds or fruits and then moved to the site of action.It has a variety of physiological functions: to change the proportion of female and male flowers in some crops, to induce parthenogenesis, to accelerate the fruit growth of some plants, and to promote fruit setting;Break seed dormancy, advance seed germination, accelerate the elongation of stem growth and some plants pull moss;Expanding leaf area and accelerating the growth of young branches were beneficial to the accumulation of metabolites in phloem and the active layer.Inhibition of maturation and senescence, lateral bud dormancy and tuber formation.Its mechanism of action, can promote the synthesis of DNA and RNA, improve the activity of DNA template, increase the activity of DNA, RNA polymerase and chromosome acidic protein, induction of alpha amylase, fat synthetase and proteinase enzyme synthesis, increased or activation beta amylase, colorful, isocitrate decomposition enzyme, phenylalanine deaminase activity, peroxidase, indole butyric acid oxide, increase content of freedom of auxin, delay the chloroplast decomposition, improve the cell membrane permeability, promote cell growth and elongation, speed up the flow of photosynthate and storages.Growth inhibitors such as doxazole and pyractin can inhibit the biosynthesis of gibberellic acid in plants, which is also an effective antagonist of these regulators.
