Indolylacetic acid (IAA) is a kind of indole broad-spectrum plant growth regulator with somatotropin activity.
1. It can be used on adventitious root formation, such as tea tree, pepper and so on.
2. It can promote fruit-setting, fruit-enlargement, yield-increasing, such as sugar beet, tomato, cornpotato.
3. IAA can promote sprout, seed-soaking, such as rice, cotton, potato, eggplant.
Mechanism of Action:
IAA is a growth material, it can be find in any plants, even in germ, fungus, Yeast parent. IAA can expand leave in length and width. Promote root growth, increase crop production.
