Ca2+concentration in singular Cu treatment group was usually higher than that in composite group by using localization of Ca2+ antimonite precipitation technique,.And distributing of Ca2+ in composite group.has no obvious difference from control group.

运用焦锑酸钾沉淀法发现，单一Cu处理的慈姑根细胞质中的C扩+浓度要比复合处理的普遍高，而复合处理组根细胞内的c扩十分布与对照无显著的差异，只是有较少的细胞中的焦锑酸钙沉淀颗粒比对照多。

When La3 in high concentration,in spite of in short time treatment,the ratio of electrolyte exosmosis is also increased. This probabily indicated high concentration La3 can destroyed the membrance ofroot.

高浓度的镧(c＞500 ug／ml)时，即使短时间的处理，也会使电解质外渗率提高，这可能和高浓度的镧使根细胞原生质膜破坏所致。

The effect of neodymium on root tip cell was similar to that on mesophyll cell. The influence of neodymium on cell ultrastructure was more evident in root.

钕对油菜主根根尖细胞的作用与对顶叶叶尖细胞作用类似，但对根细胞超微结构影响更为明显。

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。

Almost all heavy metal ions enter root cells with the help of a metal transporter protein that are subsequently transported to the vacuole.

Observation on the ultrastructure of the radicle cell of cabbage seeds indicated that the ultrastructure changed with the seed vigor reduced, such as the segregation of cytoplasm from the cell wall, the fragmentation of cell membrane, the vesiculation of protoplasm, the homogenization of chromation, the disintegration of cytoplasm, the distinguishing of nuclear membrane and nucleous ,and so on.

胚根细胞亚显微结构电镜观察结果，甘蓝种子通过人工老化活力降低后，胚根超微结构发生了变化，主要表现为：质壁分裂，细胞膜内陷或局部断裂，细胞质空泡化，细胞器难以辨认，染色质均质化，核仁和核膜的界限模糊等现象。

Analysis indicated that the ratios of the Cd forms extracted by ethanol and by deionized water in root, and the ratios of soluble Cd in root cell showed accordancy with the ratio of Cd transported from root to aboveground parts, and also the ratios of the Cd forms extracted by ethanol and by deionized water in stem, and the ratios of soluble Cd in stem cell showed accordancy with the ratio of Cd translocated from rice straw to grain.

分析表明，两供试品种根组织中乙醇提取态和去离子水提取态Cd的比例及根细胞中可溶性Cd的比例与根系吸收的Cd向地上部的分配比例存在一致性；茎组织中乙醇提取态和去离子水提取态Cd的比例及茎细胞中可溶性Cd的比例与植株地上部积累的Cd向籽粒分配的比例间存在一致性。

If, however, the root cell is one of the rare tetraploid cells (a cell having four sets of chromosomes that arise spontaneously in the root), it may develop into a nodule.
