Abstract
The purpose of this study was to investigate shooting and fruiting characteristics of persimmon 'Hachiya' affected by sub-zero temperature at early budding stage. The number of developed shoots, and the number of shoots with young fruits, and the shooting and fruiting of terminal buds of one-year-old branch (1YOB) were significantly decreased with the sub-zero temperature treatment (SZT). The number of shoots developed in the top of 1YOB decreased 47.2% due to SZT. The number of shoots with fruits was significantly decreased at 50% or higher in non-budding rate of 1-YOB. Especially the number of fruits (Y) at the three terminal buds of 1YOB was significantly affected by SZT and the non-budding rate (X) as Y = -0.145X + 12.950 ($r^2=0.4672^*$). Therefore, in the early budding stage of persimmon, when tree is affected by SZT ($-2^{\circ}C$, 3 hours), shoots growth is reduced and increase of 10% in non-budding rate reduces 1.4 of fruits per the three terminal buds of 1YOB.
