The top three plant growth promoters are: (1) Auxins (2) Gibberellins and (3) Cytokinins. Plant Growth Promoter # 1. Auxins: Auxins are the best known plant growth regulators. They promote growth of stem or coleoptile sections and decapitated (apex removed) coleoptiles, but in the same concentration are incapable of causing growth in intact plants.

Indole-3-butyric acid (1H-indole-3-butanoic acid, IBA) is a white to light-yellow crystalline solid, with the molecular formula C 12 H 13 NO 2.It melts at 125 °C in atmospheric pressure and decomposes before boiling. IBA is a plant hormone in the auxin family and is an ingredient in many commercial horticultural plant rooting products.
