镉

Based on the evaluation system, the plants whose relative remediation age was between 0~10 years were named as"Hyperaccumulator"and those between 10 ~ 50 years were named as"Accumulator".7 In the experiments six kinds of substrates were mixed with different solid wastes and the absorption and enrichment of plants on heavy metal Cd was studied. The results showed that relative remediation age was an ideal index to evaluate the capability of the phytoremediation on heavy metals, because it took into account more factors which affected the absorption evaluation effects than others, such as the heavy metal content and the biomass of the over-ground part of plants, the heavy metal content and the whole gross in substrates, harvesting frequency of plants and the environment standard of heavy metal. This made relative remediation age be suitable to the sorption capability evaluation of not only different plants on one heavy metal but also one plant on different heavy metals.8 It can be drawn from the relative remediation age of heavy metal Cd that the absorption capability of different plants was not same.

以相对修复年限为评价指标定义相对修复年限为0-10年的植物为"超富集植物"，10-50年的植物为"富集植物"。7在由不同废弃物按一定的比例混合配制的六种土地复垦基质上，系统地研究了几种植物对重金属镉的吸收和富集情况，结果表明，相对修复年限既适用于不同植物对同一种重金属元素的吸收能力的评价，又适用于同一植物对不同重金属元素的吸收能力的评价，是衡量重金属元素植物修复效果的理想指标。8从不同植物对同一基质重金属镉的吸收和富集能力看，不论是经过多年种植的基质，还是第一次种植的基质，小白菜和油菜都是相对理想的植物；而黑麦草、高羊茅和苜蓿的吸收效果并不理想。

We suggest that these proteins be tightly connected with mithridatism of cadmium in BG cells and, as protein markers in part, be suit for monitoring pollution level of cadmium and developing the research focused on toxicology.

Nasturtium officinale was cultivated in Steinberg medium with different concentrations of Cd2+ or Cu2+ for three days to study the effect of these two kinds of heavy metals on the plant growth.

以不同质量浓度的铜和镉处理3d的西洋菜为实验材料，研究了短期培养条件下镉对西洋菜生长的影响。

Mol·L~(-1) individually and also with both heavy metals present. Plasmolysis, concentrated cytoplasm, disappear ance of the cristae of mitochondria, ambiguity of framework and destruction of mitochondria envelope were all symptoms of root cells under Cu stress; hollowing cells was also found in Cd treatment, and there existed some different granule in these hollowing cells.

铜使根细胞产生质壁分离、细胞质浓缩、部分细胞空泡化，使线粒体脊突消失、结构模糊、外膜破坏；镉使根细胞空泡化，并在部分空泡化的细胞里产生大小不等的颗粒状物；铜、镉交互污染使根细胞受害程度加深，并兼有两者的受害症状特征：线粒体结构彻底破坏、空泡化细胞里的颗粒物更大电子密度更高、质壁分离现象更普遍、质膜上的颗粒物沉淀更大。

Result The germination percentages of maize and dry radish, and the seedling heights of Shawo radish, maize and dry radish were reduced with the increase of the cadmium concentration. The cadmium had a remarkable restraining effect on the length of main radicel of 4 kinds of crops.

结果］玉米与旱萝卜的发芽率，沙窝青萝卜、玉米和旱萝卜的幼苗高度均随镉浓度的增加而降低；镉对4种作物的胚根伸长抑制效应十分明显。
