Abstract:
‘American Dasusheng’ lettuce was used as material,the effects of exogenous sodium sulphate on the glutathione content and glutathione metabolism-related enzymes in lettuce seedlings under copper stress were studied by filter paper culture method.The results showed that,1)Root length of lettuce seedlings were inhibited under 30 μmol?L-1 copper treatment.Malondialdehyde (MDA) content,reduced glutathione (GSH) content and glutathione reductase (GR) activity were enhanced significantly (P<0.05);2)Compared with 30 μmol?L-1 copper treatment,root length,GSH content,and glutathione peroxidase (GPX) activity increased,while MDA content decreased under the application of sodium sulphate.It was suggested that exogenous sodium sulphate could affect glutathione metabolism-related enzymes in lettuce seedlings under copper stress,and mitigate the damage of copper stress to lettuce seedlings via regulating the GSH content and GPX activity to alleviate oxidative stress.The strongest effect on alleviating copper stress was found in the treatment of 0.50 mmol?L-1 sodium sulfate.
