MICROPROPAGATION OF CEPHALOTAXUS-HARRINGTONIA

Shoot proliferation of Japanese plum yew [Cephalotaxus harringtonia (F orbes) K. Koch] derived either from a seedling or from a mature clone was achieved in a medium based on Murashige and Skoog salts supplement ed with vitamins and casein hydrolysate in the presence of 10% (v/v) c oconut water. Rooting was unsuccessful from microcuttings proliferated on agar-based medium, but, when cultured in liquid medium on membrane rafts, detached shoots rooted under mist in greenhouse conditions wit h or without auxin treatments. Rooted microcuttings successfully accli mated to greenhouse conditions.
