摘要
本文报道多种频率的脉冲磁场作用于蔬菜种子,提高种子活力,进而研究脉冲磁场的生物效应实验表明:脉冲磁场强度在一定的阈值内,作用一定的时间,种子活力将提高,出现正的生物效应(刺激效应),而超过这一阈值范围.种子将出现负的生物效应(抑制效应).
The authors have studied the effects of the pulse magnetic field on vegetable seeds and its bioeffects.The experiments have showed that, within a limit of threshold,the pulse magnetic field could improve the vigour of the seeds.However,beyond this limit,it would cause negative effects.
