水鳖

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

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

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

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 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 .

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；

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 .

随着Hg2+浓度的增加，水鳖叶片中叶绿素含量、叶绿素a/b值、CAT活性逐渐减小，而SOD、POD活性、可溶性蛋白含量则先升后降。

As increasing of the concentration of Hg 2 + , the content of chlorophyll , chlorophyll a / b values , the activity of CAT decreased , but the activity of SOD , POD , the soluble protein content of the leaves increased first and decreased afterwards .

Cr~（6+）污染对水鳖的超微结构及菱、莼菜、黑藻细胞膜的影响

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

电镜观察发现，水鳖叶细胞遭受Hg2+毒害初期，染色质凝集，叶绿体中类囊体片层以及线粒体嵴突膨胀。

Ultrastructure observation revealed that the chromatin condensed , the thylakoids of chloroplast and cristae of mitochondria swelled at the early stage when the leaves suffered the poison of Hg 2 + .

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 mainly showed : plasmodesmata fractured , nuclei deformed in different ways , chloroplast enlarged , granum disorganized .

从生物量分配上而言，凤眼莲分配到根系生物量的相对比率比水鳖的高，水鳖的主要在冠部，表现出两物种在资源利用策略上的不同。

The relative biomass allocation to root of water hyacinth was higher than that of H , dubia , and the later mainly to shoot . These two species showed difference in resource use strategies .

这里的生态环境优良，山中的茶油、茶叶、板栗、山野菜，水里的鱼鳖虾蟹，都是纯天然的绿色食品。

Here is an excellent ecological environment , the mountains of tea oil , tea , chestnut , mountain vegetables , shrimps and crabs wa Fish and turtle ter are all pure natural green food .
