Abstract:
Taking 5-year-old ‘Kyoho’ grape as material,with the shoots germinated from cane of two trellis(scaffolding and wire rack),hearts were picked by keeping 2~4 leaves after the first blossoming respectively in order to force the hibernacula to sprout,while all summer bud vice tips were pruned.The effect of different new branch treatment methods on the flowering rate,fruiting branch rate,ear size and quality were studied,and the relation between branches-based crude and ear size was discussed.The results showed that the highest flowering rate was the hibernacula germinated from the shoots which were picked hearts by keeping 4 leaves after the first blossoming.The average fruiting branches rate and the ratio of the middle ear with scaffolding 〖JP3〗were higher than that of wire rack.And the fruit quality with scaffolding was significantly better than that of wire rack.The fruiting branches-based crude and ear size showed significant positive correlation.
