Abstract

Effects of stress of copper,cadmium on carbon and nitrogen assimilate translocation in winter wheat were investigated in a potted plant culture experiment.The six treatments were Cu_1(100 mg/kg),Cu_2(200 mg/kg),Cu_3(300 mg/kg) and Cd_1(10 mg/kg),Cd_2(50 mg/kg),Cd_3(100 mg/kg),and CK(0mg/kg) was no heavy metal.The results showed that,compared with CK,Cu,Cd reduced the amounts and remobilization rate of pre-anthesis stored assimilates and total amount of pre-anthesis stored assimilate and grain weight.Effects of Cu_2,Cd_2 treatments on that of leaf and Cu_3,Cd_2 treatments on that of stalk and sheath and total amount were the maximum.The amounts of pre-anthesis stored nitrogen and nitrogen accumulation in grain were reduced with increasing of the concentration of copper and cadmium.But changes of remobilization rate of pre-anthesis stored nitrogen were complicated.The grain yield and content of starch and protein were reduced with increasing of the concentration of copper and cadmium.
