Abstract

In this study, we conducted a growth and yield survey of 'Kibou', a registered variety of wild grape for wine at Shinshu University, using 'Kibou' cultivars grown at the university. The test plots were divided into 4 test sections according to the presence or absence of tipping treatment and degree of cluster thinning, and growth and yield surveys were conducted for 3 years from 2020 to 2022. The results showed that in the unrestricted cultivation zone (no tipping treatment plots) tended to have stronger nutritional growth than that in the pruned zone (tipping treatment plots). In 2020, yield was significantly greater in the three-bunch area than in the two-bunch area, but there was no significant difference in fruit quality among the four test sections. Yield and fruit quality did not differ significantly among the four test sections in 2021 and 2022. These results suggest that the cultivation management practices like number of fruiting bunches and tipping were harvested little effect on fruit quality.
