Abstract: | Kinetin and the embryo axis acted similarly in bringing abouta promotion of amylase activity in cotyledons of Phaseolus vulgaris.No promotive effect of gibberellic acid or indole-3-acetic acidon amylase activity could be detected. It is suggested thatthe regulatory action of the embryo axis on starch degradationin the cotyledons of P. vulgaris is mediated by cytokinins. (Received May 4, 1970; ) |
