Indolyl‐3‐butyric acid and vitamin D 3 enhance adventitious root formation in green cuttings of Populus tremula L. A significant synergistic effect is observed between these two substances. The number of roots formed on application of the individual substances and on simultaneous application depends on the growth substance concentration, the timing of application, the age of the cuttings and the number of leaves. Of the vitamin D 3 animal metabolites tested, only 1,25‐dihydroxyvitamin D 3 markedly promoted adventitious rooting, and this to a lesser extent than vitamin D 3 itself. The 3‐O‐glucopyranosides of vitamin D 3 and the vitamin D 3 animal metabolites, promoted rooting to the same extent as the parent compounds.
