摘　　要：探讨了微直流电对石防风原生质体生长的影响．用０．１～１．５μＡ直流电处理培养中的原生质体，明显提高细胞团的形成数量．这一促进作用与电处理的时间长短有关，只有处理时间充分长时才有效果．阈值时间的长短随电流强度的增大而减小．After weak direct electric currents,ranging from 0. 1￣1. 5μA,stimulated the protoplasts of Peucedanum terebinthaceum for several hours,the number of cell aggregate derived from the protoplasts dramatically increased. The effect was related to the duration of the treatments and exhibited only when the duration was longer than the threshold time. The effect was not related to the start time of the treatments in culture of the protoplasts.
