Whole-plant imaging for studying the complete carbon kinetics involved in photosynthesis and subsequent photoassimilate translocation and unloading was achieved using a positron-emitting tracer imaging system (PETIS) in combination with
11CO
2 gas tracer. In an experiment with a soybean (
Glycine max cultivar Jack) plant, it was confirmed that the dynamic PETIS image data obtained followed the conservation law for total carbon. Thus, the proposed PETIS technique is a feasible noninvasive and quantitative solution to study the carbon dynamics over an entire plant in environmental and agricultural studies.
