Stigmasteryl-β-D-glucoside as an auxin synergist

摘要

The presence of an auxin synergist was confirmed in the neutral fraction of extracts from peanut plants (Arachis hypogaeaL.). The main component resposible for the activity was established as stigmasteryl-β-D-glucoside. It promoted markedly the elongation ofAvenacoleoptile segments induced by indoleacetic acid (IAA), but was only weakly active in the absence of IAA
