摘要：

Copper (Cu) tolerance and accumulation in Elsholtzia splendens Nakai were investigated by means of hydroponic culture. Enhanced growth was observed when plants were exposed to 50 and 100 muM Cu. Copper uptake efficiency and translocation depended on Cu concentration in nutrient solution. Shoot Cu concentrations of 1133 and 3417 mug g(-1) dry wt were achieved by 500 and 1000 muM Cu supply, respectively. Copper accumulation in E. splendens was accompanied by the ability to maintain the concentrations of other essential nutrients, except potassium, within the range considered sufficient for normal growth of higher plants. The results obtained suggest that E. splendens has a great potential for phytoremediation.
