Abstract

Taking pepper variety 'Xinyu 8819' as experimental material,the effects of different concentrations of CuSO4 soaking on the germination of pepper seed and growth of seedling were studied.The results showed that when CuSO4 concentration was lower than 0~100 mg/L,it could increase plant height,fresh weight and root length,chlorophyll content and POD activity.With the increasing of CuSO4 concentration,the inhibitory effect on the germination of pepper seed was stronger,and plant height,fresh weight and root length,chlorophyll content and POD activity decreased obviously.
