ROOTING OF CUTTINGS AND GROWTH OF NURSERY STOCKS OF MKR1, A DWARFING ROOTSTOCK FOR KAKI©

Miyazaki Kaki Rootstock No. 1 (MKR1), formerly named Rootstock-b and OD-1, are promising dwarfing rootstock for kaki (Diospyros kaki Thunb.). We previously showed the results of cutting propagation of MKR1 and growth of ‘Fuyu’ and ‘Hiratanenashi’ trees grafted on MKR1 (Tetsumura et al., 2011, 2012, 2013). In Japan an evaluation test of kaki rootstocks is planned and 17 prefectural research stations will participate in the test. In the test, other promising kaki dwarfing rootstocks such as ‘Shizukadai 1 gou’, ‘Shizukadai 2 gou’, and SH-1 will be provided as well as MKR1. However, timing of rooting of MKR1 cuttings and growth of MKR1 nursery stocks soon after grafting have not been reported yet. Hence, the objective of this study is to investigate the above-mentioned characteristics of MKR1 and to discuss future experiments which are necessary for commercial use of the kaki dwarfing rootstocks.
