To clarify the mechanism of the growth and development of fruits such as eggplant and tomato in relation to plant growth and yield, examination of the import of dry matter into fruits from other organs such as leaves is essential. Positron-emitting tracer imaging system (PETIS) noninvasively visualizes movement of C-labeled photoassimilate in plants. So we fed CO to a leaf and monitored the translocation of C-labeled photoassimilate into the eggplant fruit by PETIS.
