Real-time monitoring and analysis of nutrient transportation in a living plant using a positron emitting tracer imaging system (PETIS)

Matsuhashi, Shimpei

We visualized the uptake and transportation of nutrition in a living plant using positron-emitting tracers and mathematical analysis of the data. We have been developing a positron-imaging technique to visualize the uptake and transportation of nutrients in a plant by a positron-emitting tracer-imaging system (PETIS) using positron-emitting nuclide-labeled compounds. The PETIS data is analyzed mathematically to understand the physiological meaning of the physical parameters. In this study, the results on the uptake and transportation of nutrients, which were obtained with the use of a positron-imaging method, are introduced.
