Abstract

A naturally occurring compound that induces curvature in the Avena coleoptile test has been found in young orange fruits. Cochromatography with C14-labeled indole-3-acetic acid, plus excitation and fluorescence spectra determinations, indicates that this compound is not one of the known indoles or gibberellins.
