title: Distribution of gibberellin-like substances in light-and dark-grown seedlings of Phaseolus multiflorus.
abstract: Lettuce and barley endosperm bioassays of successive eluates from a phosphate-buffered celite column detected two gibberellin-like compunds, Phaseolus I and Phaseolus II, in extracts of both light-and dark-grown seedlings of Phaseolus multiforus. There were differences in the gibberellin content of light-and dark-grown seedlings, the former containing more Phaseolus I but less Phaseolus II than the latter. An examination of the gibberellin content of leaves and apical buds, stems, cotyledons, and roots of light-and dark-grown seedlings revealed distinct qualitative and quantitative differences in the distribution of Phaseolus I and Phaseolus II.
