Formulated with addition exogenous, it can increase the activity of endogenous auxin synthase in plants in a short time and induce the synthesis of endogenous auxin and gene expression,indirectly promotes cell division, elongation and expansion, induces the formation of rhizomes, and is beneficial to new root growth and vascularization system differentiation,promotes the formation of adventitious roots of cuttings.

INDOLE-3-BUTYRIC ACID POTASSIUM SALT (IBA-K) is a plant growth regulator that promotes crop rooting. It is mainly use to promote the growth of crop capillary roots. When combine with Naphthalene acetic acid (NAA), it can be made into rooting products.
