The Effects of Different Light Intensity of UV-B on the Catalase and Peroxidase Activities of Lemna minor

WANG Ting,LIU Chun-chen,WANG Ren-jun,YAO Shu-min,ZHOU Jing,SHA Wei-lai(College of Life Science,Qufu Normal University,273165,Qufu,Shandong,PRC)  
The experiments aim to explore the possible effects on catalase and peroxidase by measuring the catalase and peroxidase activities of Lemna minor that exposed to different light intensity of UV-B.The experiments set five radiation intensity,the results indicate that within the scope of different radiation intensity,the catalase activity changed from activation to inhibition with treatment intensity increasing;peroxidase activities tended to decline in the short time treatment,then a little increased,and reached the maximum volume of POD activities,this could be explained to adaptation of Lemna minor on UV-B radiation,and peroxidase activity decreased evidently after the longest time treatment.
