Mechanism Exploration and Effects of Electrostatic Field on Comprehensive Biological Characteristics of Mung Bean Seeds

绿豆种子经不同强度的均匀高压静电场作用一定的时间 ,实验观察种子的发芽情况 ,统计经不同强度静电场作用后的种子的发芽率、活力指数 ,分析其幼芽抗旱性的变化 ,测定种子的浸泡液电导率及种子的淀粉酶和过氧化物酶的变化 ,对产生变化的机理进行了分析。实验证明 ,通过适当的静电场处理 ,绿豆种子的浸泡液电导率明显降低 ,淀粉酶和过氧化物酶的活性明显提高 ,相应的种子的发芽率和绿豆芽成活率及抗旱能力也明显提高。不同强度的静电场影响效果有所差异。场强为 4kV/cm的静电场对绿豆种子的发芽及其芽期生长的综合影响效果最佳 ;场强为 2kV/cm和 5kV/cm时 ,对芽期的抗旱能力有明显的促进作用 ;场强为7kV/cm时 。

The uniform high pressure electrostatic field with different strengths is applid to Mung bean seeds.It is required for the experiment to observe the germination of Mung seeds,to count the germination rate and vitality index of Mung seeds,to analyse the plumule drought resistance,to measure the soak conductivity,seed anylase or peroxidases,and to analyse its mechanism,after the seeds are processed with the different strenghts electrostatic field.The experiment proves that after processed through the proper electrostatic field,the soak conductivity of Mung bean seeds can be reduced obviously,and the vitality of anylase and peroxidases can be increased remarkably.And the germination rate of the corresponding seeds,the vitality rate of Mung bean sprouts,and its drought resistance property can be increased remarkably.However,the effects are different for the electrostatic field with different strengths.When the field strength is 4 kV/cm,the comprehensive effects of the electrostatic field on Mung bean germination and sprout growth will reach the optimization.When the field strenght is 2 kV/cm and 5kV/cm,the sprout ability of drought resistance will be promoted obviously.When the field strength is 7 kV/cm,the germination and the drought resistance ability of Mung bean seeds will be restrained.
