Product Details
3-Indoleacetic acid is a powerful growth stimulant for lower plants, naturally generated by multiple fungi such as yeast and extracted from strains including Aspergillus niger and Rhizopus species. It enjoys extensive application in both horticulture and industrial sectors.
Indole-3-acetic acid (IAA, CAS No. 87-51-4) is a naturally occurring plant auxin mainly used in agriculture to promote root formation in plant cuttings, prolong the freshness and storage life of cut flowers and fruits, and regulate overall plant growth and fruit development.
Moreover, it is widely used in horticultural tissue culture, improving plant stress tolerance, and supporting research on plant physiological mechanisms.
Appropriate control of application concentration is essential to avoid potential growth inhibition effects on plants.
