该方法由我们小组开发，使我们能够对活植物进行定量分析。它已被应用于研究植物中锗、镓、溴和砷等重元素的运输。这些重元素通过维管束输送到叶片，吸收后其浓度随时间的变化可以清晰地观察到。已证实，该运动取决于元素、吸收方式和植物生长状态。除了所提供元素的移动之外，植物中的一些元素在质子照射下还表现出有趣的变化。人们发现该方法对于检查活植物中的元素运动非常有效。
The method, which was developed by our group, enables us to perform quantitative analysis of living plants. It has been applied to investigate the transport of heavy elements such as germanium, gallium, bromine and arsenic in plants. These heavy elements are transported to the leaf through vascular vessel, and changes of their concentration with elapsed time after absorption could be clearly observed. It was confirmed that the movement depends on elements, on the manner of absorption and on the states of plant growth. In addition to the movement of supplied elements, some elements in the plant show interesting changes in response to proton irradiation. It was found that the method is quite effective for examining elemental movement in living plants.
