Indole-3-butyric acid - Wikipedia
WEBIndole-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.
WEB39 IBA is a plant hormone in the “auxin”group. It is applied exogenously and used as a plant growth 40 regulator (EPA, 1992). IBA exerts different effects on plant growth and development, e.g. regulating 41 responses of plants against biotic and abiotic stresses (Tognetti et al., 2010), or increasing plant yield (Amin

WEBMar 4, 2005 · Like IAA, exogenous IBA inhibits arabidopsis root elongation (Zolman et al., 2000) and induces lateral (Zolman et al., 2000) and adventitious (King and Stimart, 1998) root formation. IBA, originally classified as a synthetic auxin, is in fact an endogenous plant compound (Epstein and Ludwig-Müller, 1993; Ludwig-Müller, 2000; Bartel et al., 2001).
