Toxicity of nickel and cadmium in spruce seedlings: Effect of separated and combined treatments on peroxidase and superoxide-dismutase activity

摘要: separately and simultaneously. The kinetics of metal assimilation total accumulated quantity depended on the type treatment. Following exposure, an increase in peroxidase activity seedlings treated with Cd Ni/Cd, superoxide-dismutase during Ni/Cd treatment was observed. A parallel change isoenzyme pattern occurred. There a good correlation between metals needles enzyme activities. effect measured parameters shown to be stronger comparing Ni. results obtained show that could used evaluate capacity one part defense system spruce withstand stress.
