| 摘 要： | 研究了在 Hg2 + 、DBS胁迫下 ,浮萍 (Lemna minor L.)植株的枯死率、叶绿素含量和可溶性蛋白质含量的变化。植株的枯死率随 Hg2 +、DBS浓度升高和处理时间的延长而增加 ;叶绿素和蛋白质含量随 Hg2 +和 DBS浓度升高和处理时间的延长而逐渐下降。在 Hg Cl2 、DBS浓度分别为 6mg/L、1 2 mg/L时 ,约 70 %的浮萍 1 0 d内仍存活。 |

| Abstract: | The injury degree of Lemna minor by the stress of Hg 2+ and DBS are reported.The concentrations of chlorophyll and dissolved protein decrease with the increase of Hg 2+ and DBS concentrations or as treatment time is continued,dead percentage increase with the increase of Hg 2+ and DBS concentrations or as treatment time is continued.When the concentrations of HgCl 2 is 6mg/L or DBS is 12mg/L,about 70% of Lemna minor can live for 10 days at least. |
