| Outline of Final Research Achievements |
Metallic elements such as iron and zinc play an important role in the growth and life activity of plants. It is expected that the in-vivo observation of these metallic elements in plants enables to elucidate their metabolism mechanism at a molecular level and it becomes useful for the selective breeding and the artificial cultivation. We developed a 3D RI imaging system based on the use of RI source emitting only x-rays (X-ray RI source) and the principle of a pinhole camera. We succeeded to perform 3D RI imaging by using a 55Fe source as the X-ray RI source. We applied it to investigate the movement of 55Fe tracer in a sprout of Japanese mustard spinach. We obtained the time change of distribution of 55Fe tracer in the plant and found that the 55Fe accumulation in leaf became remarkable after a period of time after administration of 55Fe.
