title: Biological Activity of O-beta-d-Glucopyranosylzeatin.
abstract: Concentrations of 10(-8) to 10(-5)m O-beta-d-glucopyranosylzeatin are less active than zeatin and zeatin riboside in the soybean (Glycine max L.) callus bioassay. At a concentration of 10(-4)m the glucoside was, however, more active or alternatively less toxic than similar concentrations of zeatin and zeatin riboside. Applied zeatin-O-glucoside is readily metabolized by soybean callus and both zeatin and zeatin riboside could be extracted from callus grown on basal medium containing the O-glucoside.
