摘要
报道了铅锌矿区经历不同重金属污染年代的曼陀罗 (DaturastramoniumL .)种群的蛋白质代谢动态变化情况 ,结果表明重金属污染在短期内能抑制曼陀罗种群的蛋白质含量及代谢 ,但随着污染年代的推移 ,曼陀罗种群的蛋白质代谢的朝着无污染的正常值方向回复 ,说明在长期重金属污染胁迫下 ,曼陀罗在生理上获得了对重金属的抗性 ,但其抗性的分子机理机制尚不清楚 .
The dynamic changes of total proteins metabolism of Datura stramonium L,exposed different heavy mental pollution durations,are reported.The result shows that heavy mental pollution can restrain the protein contents of Datura stramonium which has been growing in polluting areas in short time.On the other hand,with polluting years prolonging,the changing rules begin to recover similarly to the initial (population CK) and population L obtains resistance to heavy mental.However,the mechanism of resistance is unknown and need further be studied.
