Effects of pruning time and pruning intensity on the formation of wound wood at cut surfaces of ‘Cerasus speciosa (Koidz.) H. Ohba’ planted in a city park

Abstract

In this research, we surveyed the formation of wound wood at pruned points by the pruning examination of Cerasus speciosa (Koidz.) H. Ohba in a city park. As a result, the wound wood formed at 87 % of all pruning points, and we considered that the pruning management for C. speciosa is possible in city parks. Moreover, the differences of pruning time did not effect formation of the wound wood and the rate of covering. Therefore, time of after flowered is an appropriate time of pruning to achieve substantial amount of flowering. However, it was suggested that attention be necessary for the diameter of the pruning branch to increase formation of wound wood.
