Abstract:

Abstract: Soybean、cucumber and chinese cabbage seeds were treated with different strength electrostatic field before its were planted. The changes of the soluble protein content, POD activity, chlorophyll content and the kinetics of chlorophyll a fluorescence in leaves of crops were measured. The results indicated that the different crops had different physiological reactions in leaves when seeds were treated with different strength electrostatic field. When seeds were treated with feasible strength electrostatic field , the soluble protein content , POD activity and chlorophyll content in leaves were increased, the potential activity and the efficiency of primary conversion of light energy of PSⅡ in leaves were improved.
