Description

Application

Indole-3-butyric acid (IBA) has been used as a standard to monitor IBA in urine samples by tandem mass spectrometry-selected reaction monitoring (SRM) and Ultra-high performance liquid chromatography (UHPLC), as a standard for high performance liquid chromatography (HPLC) for the quantification of IBA in foliar tissues of Coffea canephora seedlings.

Biochem/physiol Actions

Indole-3-butyric acid (IBA) is a naturally occurring phytohormone auxin (plant growth regulator). It promotes root formation in cuttings but does not affect ethylene levels. IBA might be a precursor for indole-3-acetic acid (IAA) through β oxidation pathway. IBA is present in plant species like Zea mays, Pisum sativum and Arabidopsis. IBA is more potent than IAA for inducing root formation.
