1. Studies were made on the translocation of photosynthates using a tracer technique. The radioactivity was measured by a cintillation counter.2. It was proved that a summer cycle shoot was a powerful sink and a large amount of 14C was translocated to the part. When it was detached, somewhat higher activity of 14C was observed in the underground part of the tree.3. In increasing fruit number per tree, total activity of 14C in the fruit part was increased but the activity per ml of juice or unit weight of plant parts was lowered. Basipetal movement of 14C was also decreased with much fruiting.4. Application of GA3 or kinetin solution on fruit surface, increased the movement of photosynthates into the fruit. While the application of CCC depressed the translocation of photosynthates. The 14C in the juice might be mainly originated in sugars translocated from the leaves.
