Abstract:
Tomato variety of ‘Zhongshu No.4’ was used as test material，a hydroponic experiment was conducted to investigate the effects of exogenous selenium (Se) on the plant growth，root activity，as well as chlorophyll content，malonaldehyde (MDA) and SOD，POD，CAT activity in leaves of tomato seedlings under Ca(NO3)2 stress.The results showed that，the application of 0.010 mmol?L-1 exogenous Se significantly alleviated Ca(NO3)2 -induced growth inhibitation by increasing root activity，photosynthetic pigment content and the defense ability of antioxidant enzymes system to decrease membrane lipid peroxidation and protect the integrity of membrane structure in tomato seedlings under Ca(NO3)2 stress.The application of 0.200 mmol?L-1exogenous Se significantly lowers root activity and pigment content under Ca(NO3)2 strress and thus intensified the inhabitation of Ca(NO3)2 stress to tomato seedlings.But the application of 0.500 mmol?L-1 exogenous Se maight directly lead to the death of tomato seedlings.
