碳动力学进入水果是一个农业问题的生长和发展的汇器官被收获。其中，光合产物的运转和分配是理解光合作用机理的重要课题。在本工作中，使用碳-11标记的二氧化碳和正电子发射断层扫描（PET）对碳-11（C-11）标记的光合同化物向番茄果实中的转运进行了成像。在完整的植物体中，定量地获得了C-11活性逐渐增加的动态PET数据及其分布。这表明，三维光同化物到果实的运转是成功地成像和碳动力学分析，以了解植物生理和营养。
Carbon kinetics into the fruit is an agricultural issue on the growth and development of the sink organs to be harvested. Particularly, photoassimilate translocation and distribution are important topics for understanding the mechanism. In the present work, carbon-11 (C-11) labeled photoassimilate translocation into fruits of tomato has been imaged using carbon-11-labeled carbon dioxide and the positron emission tomography (PET). Dynamice PET data of gradual increasing of C-11 activity and its distribution is acquired quantitatively in intact plant body. This indicates that the 3-D photoassimilate translocation into the fruits is imaged successfully and carbon kinetics is analyzable to understand the plant physiology and nutrition.
