There are currently five recognized categories of phytohormones, namely auxin, Gibberellic Acid GA3, Cytokinin, ethylene, and abscisic acid. Recently, brassinosteroids (BRs) have gradually been recognized as the sixth major category of phytohormones.

Brassinolides are available in five product categories:
(1)24-trisepibrassinolide: 72962-43-9 C28H48O6
(2)22,23,24-trisepibrassinolide :78821-42-9
(3)28-epihomobrassinolide: 80843-89-2 C29H50O6
(4)28-homobrassinolide:82373-95-3 C29H50O6
(5)Natural Brassinolide

1.This product is a plant endogenous auxin-inducing factor, which is composed of 5 kinds of plant endogenous auxins including indoles and 2 kinds of vitamins. 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. INDOLE-3-BUTYRIC ACID POTASSIUM SALT (IBA-K) can be use for cutting rooting of seedlings, as well as adding flush fertilization, drip irrigation fertilizer and other products to promote crop rooting and improve the survival rate of cuttings.
