Effect of lead pollution on tea plant grouth and activity of its protective enzymes

LUO Yaoping, KANG Mengli, Ren Mingxing (1.Department of Tea Science ,Zhejiang University, Hangzhou, 310029)  
Two varieties i.e. Longjing43 and Zhenong117, were used to study the effect of Pb pollution on tea grawth and activity of protective enzymes by pot planting experiment. The results showed that Pb could accelerate the growth of Longjing43 among the concentrations of the experiment, while the growth of Zhenongll7 was restrained when the concentration was 430mg/kg. Under the concentration of Pb (160mg/kg), the net photosynthetic rate of Zhenong117 was greatly restrained, while that of Longjing43 was enhanced. Under that of 430 mg/kg, the net photosynthetic rate of the two varieties were restrained. The activities of POD and SOD increased with increasing concentrations Pb in zhenong117. The activity of POD increased first and then decreased in longjing43, while the activity of SOD increased.
