Abstract:

In order to study the effects of different rootstocks on the growth and fruit quality of Tiangong Cuiyu grape in hot and humid area of South China, and screen the rootstock-scion combinations with good comprehensive quality, 7 kinds of rootstock were grafted with Tiangong Cuiyu, and self-grafted Tiangong Cuiyu were set as the control. The growth, economic characteristics and fruit quality of the plants were investigated and measured, the differences of the rootstock-scion combinations were analyzed, and the fruit quality of grape rootstock-scion combination was evaluated comprehensively by principal component analysis. The results showed that the flowering period of grafted plants with the rootstock of SO4, 5BB and Dogridge were earlier than that of the self-grafted plants. All 7 kinds of rootstocks could improve the fruiting rate. The yield per plant of grafted plants of SO4, 5BB and Macadams were higher than that of self-grafted plants, increasing by 1.9%, 2.4% and 10.0%, respectively. There was no significant difference in the thickness ratio of grafted plants of 5BB, Dogridge, Kangzhen No. 5, 101-14 and Macadams. The rootstocks of SO4, 5BB and Macadams could all improve the quality of grafted plants. The fruit hardness of grafted plants with 5BB was 4.07 N on average, which was 60.9% higher than that of self-grafted plants. The total sugar content of grafted plants with SO4, 5BB and Macadams was higher than that of self-grafted plants. The sucrose content of grafted plants with 5BB was higher than that of self-grafted plants, with an average of 7.97 mg·g-1, which was 33.05% higher than that of self-grafted plants. According to the principal component analysis, 5BB was the best rootstock suitable for Tiangong Cuiyu grape.
