Hydrocharis

The effect of different Hg 2+ concentrations on the content of chlorophyll, chlorophyll a/ b values, the activity of SOD, CAT, POD and the soluble protein content of Hydrocharis dubia BL. Backer were studied.

用不同浓度的Hg2+溶液培育水鳖，研究Hg2+对水鳖叶片中叶绿素含量、叶绿素a/b值、SOD、CAT、POD活性以及可溶性蛋白含量的影响。

The effects of Cd on Hydrocharis asiatica Miq and the function of Pi decreasing the stress of Cd were proved in this paper.

研究了Cd对水鳖生理生化过程的影响及Pi对Cd胁迫的缓解作用。

The effects of Cr 6+'s pollution on the ultrastructure of Hydrocharis dubia mainly showed: plasmodesmata fractured, nuclei deformed in different ways, chloroplast enlarged, granum disorganized.

Cr6+污染对水鳖超微结构的影响主要表现在：胞间连丝呈现不同程度的断裂；细胞核出现各种各样的变形；

The Effects of Cr~ ( 6+)'s Pollution on the Ultrastructure of Hydrocharis dubia and Cell Membrane of H.verticillata, Brasenia schreberi, Trapa bispinosa

Toxic Effect of Hg~ ( 2+) on Physiology and Ultrastructure of Hydrocharis dubia

Hg~（2+）对水鳖（Hydrocharis dubia）叶片生理生化及超微结构的毒害效应

Physiological and structural responses of Hydrocharis dubia leaves to different concentrations of Pb~ ( 2+) stress

水鳖叶片对不同浓度Pb~（2+）胁迫的生理和结构响应

The results showed that the growth and metabolism of Hydrocharis asiatica Miq were inhibited by Cd. The plant exhibited a decrease of the chlorophyll content, and the photosynthetic rate, an increasing of the respiration rate, the soluble sugar content and POD activity.

结果显示，Cd能抑制水鳖的代谢和生长，使叶绿素含量与光合速率下降，呼吸速率与可溶性糖含量增加，POD活性增强；
