Abstract:
lead and cadmium stress；gibberellin；hollyhock；rape；accumulation characteristicsTaking hollyhock and rape as experimental materials,the effect of spraying gibberellic (GA3) on the accumulation of heavy metals in rape under lead and cadmium stress was studied by using the method of 1:1 intercropping between hollyhock and rape and spraying GA3 with different concentrations (0，10-7，10-6，10-4 mol?L-1) under lead and cadmium stress,in order to provide reference for the treatment of cadmium and lead pollution in soil,and the improvement of crop quality.The results showed that after spraying GA3 on hollyhock,with the increase of GA3 treatment concentration,the tolerance index of hollyhock and rape to Pb and Cd increased,and the accumulation of rape to Pb and Cd decreased;superoxide dismutase (SOD)，peroxidase (POD)，catalase (CAT) of hollyhock and rape increased with the increase of GA3 treatment concentration.In the soil polluted by Pb and Cd,the method of spraying GA3 with hollyhock and intercropping with rape can be used to reduce the accumulation of heavy metals in rape,improve the aboveground biomass of rape,and ensure the quality and safety of rapeseed.
