Abstract: 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.
