Indoleacetic acid is a common auxin, as its name suggests, is a drug that promotes plant production. To talk about the role of indoleacetic acid, let's first look at the molecular formula of indoleacetic acid:
What is the role of indole acetic acid? Indoleacetic acid is an organic substance, also known as auxin, auxin, and iso- auxin.
The role of indole acetic acid:
Used as a plant growth stimulating hormone and analytical reagent. 3-indoleacetic acid and 3-mercaptoacetaldehyde, 3-indole acetonitrile, ascorbic acid and the like are naturally occurring in nature, and the precursor of 3-indole acetic acid biosynthesis in plants is tryptophan. The basic function of auxin is to regulate the growth of plants, not only to promote growth, but also to inhibit growth and organ formation. In the plant cells, èŒ ç´ ä¸ä»… ä¸ä»… 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在, indole acetic acid arabinose and guanidine acetyl glucose. This may be a way of storage of sputum in the cell, and it is also a detoxification method to remove excess auxin.
At the cellular level, auxin can stimulate the formation of cell division; stimulate the cell elongation of the branch, inhibit the growth of root cells; promote the differentiation of xylem and phloem cells, promote the rooting of cuttings, and regulate the morphogenesis of callus.
At the organ and whole plant levels, auxin works from seedling to fruit ripening. Auxin inhibits the reversible red light inhibition of mesocotyl elongation in seedlings; when the indole acetic acid is transferred to the lower side of the shoots, the shootability of the shoots occurs; when the acetic acid is transferred to the backlight side of the shoots, the directionality of the shoots is produced. Indole acetic acid causes apical dominance; delays leaf senescence; auxin applied to leaves inhibits shedding, while auxin applied to the paraxial end of the layer promotes shedding; auxin promotes flowering, induces development of parthenocarpic fruit, and delays fruit ripening.
The role of indole acetic acid is briefly introduced here.
