Abstract: The aim of this experiment was to discover difference of protective enzyme activity and study effects of metabolism assimilation in soybean leaves by spraying different plant growth regulators(PGRs).It was also to provide references for anti-aging and increasing function of metabolism assimilation in the pod filling(R5)stage.Field experiments was conducted the effects of different PGRs on metabolism assimilation and activity of protective enzyme,and Kennong4 variety was selected to avoid the impact of genetic factors in 2006.The results showed that three regulators(SOD simulation material(SODM),Choline chloride(Cc)and Diethyl aminoethyl hexanoate(DTA-6)increased SOD and POD activity with a continuation of spraying time in soybean leaves.SOD activity of DTA-6 was the highest,followed by SODM;POD activity of SODM was the highest,next came Cc.In addition,SODM and DTA-6 also increased the CAT activity of leaves at a certain extent,enhanced soluble proteins,soluble sugar,as well as to nitrate content of free amino acids,and slowed down the increase of MDA.But Cc was not obvious.The above results indicated that it is effective to enhance the antioxidant capacity and slow down the senescence of its leaves,and maintaining physiological assimilation function of its metabolism assimilation and activity of protective enzyme in soybean leaves.

Key words: Plant growth regulators, Soybean, Protective enzyme, Metabolism assimilation
