Product Application
Indole-3-acetic acid (IAA, CAS#87-51-4), a natural plant auxin, is mainly used in agriculture to boost rooting of cuttings, protect blossoms and fruits, and regulate plant growth and fruit maturation. It is also used in horticultural tissue culture, plant stress tolerance regulation, and physiological mechanism research. Proper concentration control is required to prevent growth suppression.
