Abstract:
PEG 6000 solution was used to simulate drought stress,the growth and protective enzyme activities of white clover were studied in order to provide the basis for elucidating the physiological mechanism of drought tolerance of white clover.The results indicated that when PEG concentration reached 10%,the dry weight and fresh weight of plants reached the highest level.The content of MDA decreased first and then increased with drought degree,it reached the lowest when PEG concentration was 5%.The SOD activity reached the maximum when PEG concentration was 5%,and then decreased slowly;POD activity reached the maximum when PEG concentration was 10%,then decreased slowly;the CAT activity of the control strain was the highest.White clover had drought resistance,low concentration of PEG could promote white clover.Under mild drought conditions,SOD and POD may be key factors for drought tolerance of white clover.
