Effect of Shoot-Fruit Ratio on Grape Yield, Quality and Storage Nutrient

摘要

cqvip:With the grape variety " Summer Black" as the test material,the effects of different shoot-fruit ratios on grape yield,fruit quality and grapevine storage nutrient were investigated for 2 consecutive years,so as to determine the optimized load for Summer Black grapes in Shandong. The results showed that the grapes with shoot-fruit ratio of 1∶ 1 had the highest soluble solid content,vitamin C content and grapevine storage nutrient. Based on the comprehensive analysis,the shootfruit ratio of 1∶ 1 was the optimized load for Summer Black grapes in Tai'an of Shandong Province,and the yield was 1 179. 37-1 288. 63 kg per 667 m^2.
