| 摘 要： | 对两种不同地域的野生东南景天进行了分析。发现不同地域的东南景天在重金属积累性上存在显著差异。姚王矿区东南景天生物量约是上台门矿区的4倍。姚王矿区东南景天地上部分积累Zn最高达7850 mg/kg,上台门矿区东南景天为1623 mg/kg。积累Cd最高达到222mg/kg,上台门为37.5 mg/kg。对Pb的积累,两种景天都主要聚集在根部。对Cu的积累表现为正常植物水平。

| Abstract: | Sedum alfredii Hance from two different areas were researched in this study.The major results are as follows: Sedum alfredii from Yaowang Pb/Zn mine metal uptake ability is higher than Shangtaimen Pb/Zn mine.The highest Zn was found in Yaowang Sedum alfredii,reached 7850mg/kg,Shangtaimen reached 1623 mg/kg.The highest Cd was found in Yaowang Sedum alfredii,reached 222mg/kg,Shangtaimen reached 37.5 mg/kg.Both Sedum alfredii's major uptake Pb are in root,and uptake ability Cu is the same to common plant. |
