Abstract:
The tomato breed of ‘Hezuo-908’ and ‘Qidali’were chosen as materials，and different concentrations of Brassinolide(BR) 0.05,0.1,0.2,0.4,0.8 mg/L under salt stress were treated on tomato seedlings.The affection of BR on the physiological indexes of tomato seedlings were investigated.The results showed that the best treatment concentration of BR was 0.1 mg/L of ‘Hezuo-908’，the best treatment concentration of BR was 0.2 mg/L of ‘Qidali’.BR restrained the decrease of chlorophyll and significantly enhanced peroxidase(POD),catalase(CAT)and other plant cell protective enzyme activity of leaf and reduced the content of malondialdehyde (product of membrane lipid peroxidation) and the plasmalemma permeability，therefore the growth inhibition caused by salt stress were mitigated.
