Abstract
The application of Gibberellic Acid to Datura innoxia Mill, in 100–200 PPM concentrations, showed a favourable vegetative growth and thus an increase in the yield of the crude drug per plant, but per–centage of total alkaloids showed a slight decrease in treated plants as compared with untreated ones. Formation of flowers and seeds in the treated plants was earlier than in the controls, and the roots showed more alkaloids in the former than in latter. Possibility for exploiting the roots at harvest is suggested.
Zusammenfassung
Die Anwendung von Gibberellinsäure in Konzentrationen von 100–200 ppM wirkte sich fördernd auf das Wachstum von Datura innoxia aus, Blütenbildung und Samenansatz werden beschleunigt. Trotz erhöhten Ertrages an Rohdroge war der Ertrag an Gesamtalkaloiden etwas niedriger als bei unbehandelten Pflanzen.
