Abstract
Shoot and the fruit growth characteristics of 'Campbell Early' grape cultivar were investigated after vine thinning using the main branch leader. Before vine thinning, branch diameter was 11.8 mm, but it decreased to 9.3 mm after vine thinning. The number of shoots per vine increased to 55.9-64.5 after vine thinning. The number of fruit clusters per shoot was higher (1.5-1.75) in the vine thinning plot than in the control (0.8). Consequently, the number of clusters per vine was 98.1-106.5 in the vine thinning plot, while that in the control was 24.4-28.0. However, soluble sugar content (SSC) and tartaric acidity showed no significant differences between the control and the vine thinning plot. The proportion of >351 g fruit cluster weight after vine thinning (81.0%) was significantly higher than that of the control (32.5%). These results imply that fruit quality based on the variation in cluster weight and fruit yield was enhanced by vine thinning using the main branch leader.
