Responses of two cultivars of Brassica Chinensis to soil heavy metals Cu and Zn were investigated. The results indicate that when the soil was treated with Cu, Zn or both, the difference between the two cultivars in biomass, water content and heavy metal concentrations varied with concentrations of Cu and Zn. The sugar content in shoots of Huoqingcai was higher than that of Siyueman. When Cu and Zn coexisted, the accumulation of Cu and Zn in the roots of both cultivars of Brassica Chinensis increased in comparison with that in the treatment of Cu or Zn alone, but varied in the shoots between cultivars and between treatments.
