Abstract：Taking 4 -year -old Summer Black as experimental material,the effects of different loading amounts controlled by flower and fruit thinning on grape quality were researched in this paper.The results showed that under the open trellising cultivation,the weight of panicle and single fruit,the length and diame-ter of berry,the soluble solids in fruit and coloring degree of grape skin decreased with the increase of loading amount.Pruning of floral cluster could significantly enlarge every berry,increase the total contents of soluble solids and improve the color of grape skin,and the treatment retaining top end of clusters got better effects.In conclusion,it was optimal to retain 10 spikes per plant and prune the grape floral clusters to 5 -cm length on the 7th day before flowering.
