蓖麻——一种新的铜超积累植物

Ricinus communis,a New Copper Hyperaccumulator

研究了铜矿废弃地生长的蓖麻中Cu的分布和积累情况。结果表明,蓖麻对Cu具有较强的忍耐和较高的积累能力,是一种新发现的Cu超积累植物,可作为研究植物超积累Cu的机理和修复Cu污染土壤的植物材料。

The distribution and accumulation of Cu in Ricinus communis grown on the abandoned Cu mine in Tonglushan of Daye in Hubei Province were investigated.The results showed that R.communis had a remarkable tolerance to Cu and a potential capacity of Cu accumulation,and it was a new copper hyperaccumulator which could be used in the phytoremediation of Cu-polluted soils.
