Abstract
1.葡萄結果枝在開花前3至5天施行摘心可提高結果率。生長勢強的枝條，摘心越強，結果率越高。生長勢力中等及弱者，以中度摘心及摘除生長點的結果率爲高。過強摘心處理反而影響結果率。
2.強度及中度的摘心處理，對於生長旺盛枝條似可促進果實品質，而對於生長較弱的枝條，略爲影響果實品質，惟在統計上均未達顯著差異。
3.摘心可延遲果實成熟期3.2~6天，摘心越強，果實成熟期越遲。
1. Fruit setting percentage of the Kyoho grapes increased if pinching was made on bearing shoots 3 to 5 days before flowering. The stronger the intensity of pinching on the vigorous boots, the higher the yield. High percentage of fruit setting was obtained when moderate pinching or removing growing point were made respectively on the shoots with moderate vigor or poor growth. Fruit setting percentage showed lowered when an excessive pinching was conducted to the later case.
2. Heavy and moderate pinching treatments resulted in an improvement of fruit quality in vigorous shoots, but only slight effect on the quality of grape on the less vigorus shoots. The differences were, however, not statistically significant in both cases.
3. The maturity of fruit was delayed for 3.2 to 6 days by pinching. It is indicated that an excess pinching resulted in a delay of ripening.
