Indole-3-Acetic Acid(IAA) is a kind of indole broad-spectrum plant growth regulator with somatotropin activity.

1.IAA affects cell division and cell elongation;

2.IAA is used to stimulate rooting of herbaceous and woody ornamentals and increase the size of fruit;

3.IAA prevents blossom fall and fruit drop before fructification and fruit ripening, flower
