| 摘 要： | 应用放射性同位素示踪法, 即结合放射自显影和液体闪烁器检测及电镜放射自显影技术, 首次定性、定量地研究Ce(III)离子在辣根植物中的迁移. 结果表明: (1) Ce(III)离子能被辣根植物吸收并随时间发生迁移; (2)电镜放射自显影结果显示, Ce(III)离子迁移是通过质外体至共质体进入细胞的. Ce(III)离子在辣根植物体中的行为, 为稀土离子植物环境效应机理及辣根植物安全防护提供借鉴.

| Abstract: | The migration of a rare earth element Ce(III) in horseradish was qualitatively and quantitatively investigated for the first time. The results from the experiment are as follows: Ce(III) could be absorbed by the horseradish and could migrate with time in the horseradish, and the migration pathway of the Ce(III) in the horseradish can be revealed that the Ce(III) could enter mesophyll cells and migrate through the apoplast and symplast channels of the leaf (or plasmodesma) in the horseradish. This study of the behavior of the Ce(III) in the horseradish provided a reference point for a better understanding of the effect mechanism of rare earth elements on plant growth, environment and food safety. |
