✔ Indole Acetic Acid, IAA auxin is a kind of indole broad-spectrum plant growth regulator with somatotropin activity.
✔ In high concentrations inhibition, in small concentrations promotion of longitudinal cell growth and the related water absorption of the cells.
✔IAA auxin causes a fairly rapid increase in the cell wall extensibility in coleoptiles and young stems.
