中文摘要：

采用峰值场强为100 kV·m^-1、脉宽80 ms、脉冲频率为1 Hz的极低频高压脉冲电场（ELF-PEF ）处理-0．1 MPa的PEG -6000溶液中萌发的绿豆种子，研究了绿豆在萌发过程中鲜重、自发发光、延迟发光、丙二醛（MDA ）含量和超氧化物歧化酶（SOD ）活性的变化。结果表明，ELF-PEF对PEG胁迫下萌发的绿豆鲜重、自发发光和延迟发光积分强度促进作用分别达到了28．58％、78．35％和40．6％，说明ELF-PEF可以有效促进绿豆种子萌发过程中的生理代谢，缓解干旱胁迫对细胞的伤害作用。ELF-PEF通过提高PEG胁迫下萌发绿豆中SOD活性，降低MDA含量，缓解干旱胁迫对萌发绿豆的氧化损伤，ELF-PEF对细胞毛细吸水和代谢吸水的促进可能是其缓解干旱伤害的原因。

英文摘要：

Mung beans soaked in -0 .1MPa PEG solution were treated by extremely low frequency pulsed electric field （ELF-PEF）with peak electric field strength of 100 kV·m^-1 ,pulse width of 80 ms ,and pulse frequency of 1 Hz . Traits like fresh weight ,spontaneous luminescence ,delayed luminescence ,malondialdehyde （MDA ） and superoxide dis-mutase （SOD） activity during mung beans germination were investigated .The fresh weight ,spontaneous luminescence and delayed luminescence integral intensity in germinating mung beans were 28 .58% ,78 .35% and 40 .6% ,respec-tively under PEG stress ,indicating that ELF-PEF can accelerate the physiological metabolismand alleviate cells injury under drought stress . Although with increased SOD activity and simultaneously reducing MDA content , the oxidation damage caused by drought stress was alleviated by ELF-PEF in germinating mung beans .The promoting effect of ELF-PEF on capillary water absorption and metabolism water absorption in cells may be the cause of alleviating drought injury .
