The object of this study was to evaluate the effect of gibberellins (GA) pasting on the bourse shoot, and not just on the fruit characteristics but also on the quality, of Niitaka pear (Pyrus pyryfolia L). The fruit stalk was treated with GA (control, 25mg/fruit stalk) 35 days after reaching full bloom. In the GA-treated tree, the occurrence of abnormal bourse shoot (52.5%) increased, and the spur bud and flower number decreased. The diameter of the GA-paste-treated fruit increased during the pear growth period with GA treatment. The diameter, length, and weight of the GA-paste-treated fruit increased at harvest time, but the hardness was lower than that of the control. The differences in soluble solid, acidity, and fruit color between the control and the GA-paste-treated fruit were not significant. Post-harvest, during the storage period, the hardness of the GA-paste-treated fruit was lower than that of the control, and its weight loss ratio was higher than that of the control on the 60th days of storage.
