Application:

1 Used as plant growth stimulant and analytical reagent. 3-indole acetic acid and other auxin substances such as 3-indole acetaldehyde, 3-indole acetonitrile and ascorbic acid exist naturally in nature. The precursor of 3-indole acetic acid biosynthesis in plants is tryptophan. The basic role of auxin is to regulate plant growth, not only to promote growth, but also to inhibit growth and organ building. Auxin not only exists in free state in plant cells, but also exists in bound type Auxin which can be firmly bound to biological polymers, etc. There are also Auxin which forms conjugations with special substances, such as indolyl acetyl asparagine, apentose indolyl acetate and indolyl acetyl glucose. This may be a storage method of auxin in the cell, and also a detoxification method to remove the toxicity of excess auxin.

2 Used as a plant growth regulator, it can promote cell division, accelerate root formation, increase fruit setting and prevent fruit dropping.

3 Indoleacetic acid (IAA) is a broad-spectrum plant growth regulator of indole with auxin activity. Regulates cell membrane electron and proton channels.
