Abstract
Hydroponic cultures were conducted to investigate the copper toxicity in the growth of cabbage(Brassica chinensis L.) seedlings. Experiments in the absorption and distribution of copper in cabbage were also carried out and the copper tolerance mechanism of cabbage preliminary was pointed out in this study. The plant showed sensitive to copper. Cabbage had higher copper concentration in its root,but lower in shoot.Copper concentration in plant root and shoot was increased with the increasing of copper concentration in solution. The copper in the cabbage root was bound with low-molecular substances, which can't be elicited by copper.
