摘　　要：为了解决电场生物学效应重复性不好的问题,研究了极低频脉冲电场的生物学效应。结果发现,强度为100kV/m、频率为0.2Hz的极低频脉冲电场处理明显促进了萌发绿豆的芽长和根长生长。对绿豆幼苗超弱光子辐射的研究表明,在绿豆幼苗生长过程中自发发光呈现阶跃式增长,延迟发光积分强度逐渐升高,脉冲电场作用使得自发发光和延迟发光积分强度都有明显的提高,表明极低频脉冲电场促进了绿豆幼苗生长过程中的DNA合成反应和代谢强度,脉冲电场与植物自身电位波动的耦合共振可能是上述极低频脉冲电场生物学效应的成因。In order to solve the problem of poor reproducibility of electric field biological effects,we studied the biological effects of extremely low frequency pulsed electric field.The results showed the shoot and root growth of mung beans seedling were significantly enhanced by pulsed electric field of 100 kV / m and 0.2 Hz.Research of ultra-weak photon emission on mung beans showed that the step growth of spontaneous luminescence of mung beans appeared and the integrated intensity of delayed luminescence gradually increased in the course of seedling growth,and the pulsed electric field significantly increased spontaneous luminescence and the integrated intensity of delayed luminescence.The changes of ultra-weak photon emission on mung beans implied that the pulsed electric fields promoted the process of DNA synthesis and metabolic intensity in the growth of mung bean seedlings.The coupled resonance of the pulsed electric field and potential fluctuations in plant might be caused by the pulsed electric field biological effect.
