Abstract

The plant-growth regulators, indole-3-carboxylic acids, were introduced into N-acyl ethanolamines, and a series of N-acyl O-indolylalkyl ethanolamines were prepared. Their biological activities to regulate rape hypocotyl elongation, cucumber cotyledon expansion and common wheat coleoptile growth were tested. The results indicate that the title compounds inhibited rape hypocotyl elongation, especially the indole-3-propionic acid derivatives, whose bioactivity was better than that of indole-3-acetic acid.
