Indole-3-acetic acid is used as the plant growth hormone and analytical reagent. The active verbs such as indole-3-acetic acid and indolealdehyde, indoleacetonitrile, ascorbic acid and other active verbs occur naturally in nature. The precursor for the synthesis of indole-3-acetic acid in plants is tryptophan. The basic function of lintalin is to regulate plant growth, not only to promote growth, but also to inhibit growth and organ building. It exists not only in the free state in plant cells, but also in the binding form that can be firmly combined with biopolymer, and also in the binding with special substances, such as indoleacetyl asparagine, indoleacetic alpentose and indoleacetyl glucose. This may be a method of intracellular storage and detoxification of the extranets.
Used as plant growth regulator, indole-3-acetic acid can promote cell division and root formation, and can increase fruit setting and prevent fruit falling.
Indole-3-acetic acid is a broad spectrum plant growth regulator with auxin activity. Regulate electron and proton channels in cell membranes.
