| 摘 要： | 根据^16L4^5正交设计原理，在实验室人工培养条件下，研究了不同浓度水平的Cr^6 ,Cd^2 ,Hg^2 和Pb^2 对普生轮藻叶绿素的含量和细胞膜透性的影响，其总的趋势是随着重金属离子浓度的升高，藻体内叶绿素的含量和细胞膜透性减小，对其叶绿素含量影响的强弱顺序依次是Cr^6 ,Cd^2 ,Hg^2 和Pb^2 ，对细胞膜透性的影响强弱顺序依次是：Cd^2 ,Cr^6 ,Hg^2 和Pb^2 。

| Abstract: | s:The authors studied the effects of several heavy metal ions in different concentrations (Cd 2 ,Hg 2 ,Pb 2 ,Cr 6 ) on the chlorophyll content and cell membrance permeability of Chara vulgarie L.It was discovered that the effects of heavy metal ions on the chlorophyll content and cell membrance permeability of Chara vuigaris L. changed with their different concentration .The trend was that the chlorophyll content and cell membrance permeability were decreased with the increase of the heavy metal ions .The degree of chlorophyll content affected was Cr 6 ,Cd 2 ,Hg 2 ,Pb 2 ,and that of cell membrance permeability affected was Cd 2 ,Cr 6 ,Hg 2 ,Pb 2 . |
