the cultivation of plants in the secondary metabolism product of the induction method and the means of production

摘要

Synthesis of alkaloids by suspension cultured Catharanthus roseus cells is enhanced by stressing the cultured cells osmotically by addition to the culture of such inducers as ionic osmotic stressors such as halide salts e.g. NaCl, KCl and FeCl3 or organic osmotic stressors such as sugar alcohols and sugar acids. Synthesis of alkaloids is also enhanced by addition of anti-gibberellin compounds and other compounds such as abscissic acid which is a plant growth regulator. Yields of alkaloids are consequently increased.
