摘　　要：生物超弱发光是来自细胞的电磁信号,在揭示电磁生物学效应的机理研究中具有重要作用.为了研究极低频脉冲电场生物学效应及其机理,采用基于玉米细胞电位波动频率的1Hz极低频高压脉冲电场处理萌发玉米种子,结果发现玉米种子的萌发过程明显加快,根长和芽长均有显著增长.对萌发种子的自发发光和延迟发光的测量结果显示,1Hz极低频高压脉冲电场对萌发过程中玉米种子的自发发光和延迟发光积分强度都有明显的促进作用,表明1Hz极低频高压脉冲电场加速了玉米种子萌发过程中的DNA合成和细胞代谢.Biological ultra-weak luminescence is an electromagnetic signal from cells, which plays an important role in revealing the mechanism of electromagnetic biological effects. In order to study the biological effects and mechanism of extremely low frequency pulsed electric field, 1 Hz extremely low frequency high-voltage pulsed electric field based on the potential fluctuation frequency of corn cells was used to treat the corns during germination. The results showed that the germination process of corns was accelerated obviously and both the shoot length and root length of germinating corns were significantly longer than the control. Through the measurement and analysis of spontaneous luminescence and delayed luminescence on corns during germination, it was found that the spontaneous luminescence and delayed luminescence integral intensity of germinating corn were significantly increased under the action of 1 Hz extremely low frequency high-voltage pulsed electric field, which indicated that this specific pulsed electric field promoted the DNA synthesis and cell metabolism of the corns during germination. The coupled resonance of pulsed electric field and cell electric field in corn seeds may be the cause of biological effects of the extremely low frequency high-voltage pulsed electric field.
