Abstract:
Three kinds of vegetables (rape，lettuce，chrysanthemum)seedlings was chosen as test materials，different concentrations of CuCl2solution (0 mg/L，40 mg/L，80 mg/L，120 mg/L，160 mg/L) stress on physiological and biochemical indexes (SOD activity，POD activity，MDA content，VC content) changes were studied.The results showed that with the stress concentration increasing，three kinds of vegetables SOD，POD activity showed an increasing and then decreasing trend and the changes of activity caused by the different vegetables；the content of MDA was gradually rising trend and the changes of content caused mainly by the concentration of cadmium stress；the content of VC decreased at first and then ascending trend and the changes of content caused by the different vegetables and concentration of cadmium stress.It was speculated that chrysanthemum of resistance to copper stress mechanism may be SOD，POD activity rised evenly and rape resistance to copper stress mechanism may be related to the content of VC increased close.
