Summary Effects of gibberellic acid on morphogenesis and cardenolide accumulation in in vitro cultures of Digitalis obscura are reported. Cultures were established from hypocotyls or leaves of axenic seedlings and shoot tips of mature plants. Irrespective of the kind of explant, gibberellic acid by itself did not induce morphogenesis but modified those morphogenic responses promoted by auxins and/or cytokinins, always inhibited organogenesis and favoured both embryo formation and conversion into plants. Gibberellic acid did not significantly affect cardenolide content of plants regenerated from juvenile or mature D. obscura explants.
