Abstract
Three indole-3-acetic acid (IAA) metabolites [compounds A and B and indole-3-acetylaspartic acid (IAAsp) ] accumulated in Vicia faba roots when 14C-IAA was applied to the cotyledon. IAAsp formation was increased by the application of a high concentration (2.5 × 10−4 m) of IAA, while the accumulation of compound A was more conspicuous in the roots when a lower concentration (3.3 × 10−5 m) of IAA had been applied. This indicates that compound A is not a detoxication product induced by an abnormally high concentration of IAA.Keywords
