| Research Abstract |
MKR1, a dwarfing rootstock, made not only persimmon tree size small but also enhanced flower bud differentiation, setting many flowers, high fruit productivity, and prohibition of secondary growth and physiological fruit drop. Hence, MKR1 was proven to be a practical rootstock for persimmon. Moreover, it was shown that MKR1 controlled the genes involving flower initiation and brought the rapid increase in the number of flower primordia by the end of July. These results by MKR1 were probably caused not by the graft unions between MKR1 and scion, but by the roots of MKR1. Gibberellin and auxins, plant hormones, did not seem to control directly these phenomena.
