Effects on the Growth and Contents of Cadmium and Nutrients in Shoot of Pakchoi in Soil Contaminated by Cadmium

A pot experiment indicated that Cd(3 mg/kg and 6 mg/kg) did not affect or enhanced the growth of pakchoi,there were differences among cultivars in the effects of Cd on the growth of shoots.The concentrations and accumulations of Cd in shoots were increased with increasing Cd concentrations in soil,and significant differences were exsisted among cultivars.Cd affected nutrient elements of shoots in pakchoi,and the effects of Cd on the nutrient elements were dependent on different cultivars,different Cd concentrations and different kinds of elements.
