Abstract
Changes in nutrient medium formulation in terms of major salt concentr ation or N source significantly modified cardenolide production by Dig italis obscura (genotype T4) shoot-tip cultures. A positive correlatio n between morphogenetic responses, culture growth, and proliferative c apacity on one side and metabolite biosynthesis on the other cannot be established. The final stages of microprogation, rooting, and acclima tization of D. obscura were improved by using paclobutrazol. (C) 1997 Elsevier Science Ltd.
