Cultivation aspects of Catharanthus roseus for roots


, : Cultivation aspects of Catharanthus roseus for roots. Acta Horticulturae (73): 263-268

The results of trials with C. roseus at 3 sites showed that maximum root and ajmalicine yields were obtained after approximately 7 months of growth at a density of about 400 000 plants/ha in spaced rows. A dry soil moisture regime significantly decreased total root and ajmalicine yields, but increased ajmalicine content in the roots compared with plants grown under high soil moisture conditions. Phosphorus and nitrogen were found to be essential for intensive root and shoot growth.
