摘要: 超积累植物的确证对成功实施重金属污染环境植物修复是必不可少的。对位于湖南省株洲冶炼厂厂区的植物进行了一系列的野外调查, 以着力寻找镉的超积累植物。结果表明,商陆科Phytolaccaceae 植物商陆Phytolacca acinosa 对镉具有明显的富积特性, 商陆在镉质量分数最高达106.0mgkg-1厂区土壤中依然生长良好, 茎叶中镉质量分数高达63.8mgkg-1 。盆栽条件下, 商陆对生长介质中的镉具有很强的耐性和累积能力。当生长介质中镉质量分数为5.0 mgkg-1时, 其生物量与对照相比有所增加。随着生长介质中镉质量分数的升高, 虽然其生物量与对照相比有所降低, 但植株仍生长良好。其地上和地下部分镉的质量分数逐渐增加, 生物富集系数则逐渐降低。当土壤中镉的质量分数达到200.0 mgkg-1 时, 商陆仍能完成整个生命周期。此外, 还利用吸收量系数对商陆对镉的去除能力和富集特征进行了评价,进一步验证了商陆的镉超积累特性。图3 表5 参12

Abstract: Identification of new hyperaccumulators is of great importance to successful phytoremediation of the environment contaminated with heavy metal .A series of field investigations was conducted in the vicinity of Zhuzhou Pb-Zn Smelting Factory to search for new Cd hyperaccumulators .The results showed that Phytolacca acinosa could highly accumulate Cd .With the maximum Cd mass fraction in the leaf and stem reaching 63.8 mg kg-1 , the plant grew well in the vicinity of Smelting Factory with Cd mass fraction being as high as 106.0 mg kg-1 .An outdoor pot-culture experiment was conducted to further study metal tolerance and accumulation by Phytolacca acinosa and its potential for phytoremediation .As a result , this species had not only remarkable tolerance to Cd , but also an extraordinary capacity for this element , P .acinosa could grow quite well with Cd supplied at a level of 5 mgkg-1 and its biomass was more than that of plant in control with Cd supplied .With the Cd concentration in the media increasing , the Cd concentration in its overground parts and in the roots increased , but the bioaccumulation coefficient gradually decreased , although its biomass was less than that of plant in control with Cd supplied .As the Cd mass fraction in the soil reached 200 mg kg-1 , P .acinosa still grew well. Furthermore , P .acinosa was judged whether it was hyperaccumulator with coefficient absorption capacity .It further proved that P .acinosa had the great capacity of transporting Cd from the roots to the aerial parts .[ Ch , 3 fig .5 tab .12 ref .]
