中文摘要：

以水培方法研究了商陆（Phytolacca acinosa）在不同浓度镉、锌和铜处理下的叶绿素含量、超氧化物歧化酶（SOD）活性、生物量和组织重金属含量。结果表明，随着处理浓度增加，叶绿素含量、SOD活性和生物量呈先增加后降低趋势。组织重金属含量在镉、锌、铜为最高浓度处理时达到最高值。根重金属含量高于茎和叶。叶片中重金属含量的最大值分别为镉100．6mg／kg、锌2753mg／kg、铜36．9mg／kg。商陆对锌的蓄积能力接近于超积累植物东南景天，是一种在锰锌复合污染土壤植物修复中具有较大应用潜力的种质资源。

英文摘要：

Chlorophyll content, superoxide dismutase （SOD） activity, biomass and heavy metal content of Phytolacca acinosa under the stress of Cd, Zn and Cu were measured with hydroponics. Results indicated that with the increasing content of Cd, Zn and Cu in the solution, chlorophyll content, SOD activity and biomass increased in lower concentration while decreased in higher concentration. Heavy metal content reached the maximum at the highest treatment, with heavy metal content in the root higher than that of stern and leaf. The maximum of heavy metal content in leaf was Cd 100.6mg/kg, Zn 2,753mg/kg and Cu 36.9mg/kg respectively. The accumulation of Zn by Phytolacca acinosa was close to the hyperaccumulator Sedum alfredii Hance, which provided a potential species for phytoremediation of Mn/Zn complex contaminated soils.
