Abstract:

The purpose of this study is to screen suitable grape cultivars with leaves of proper packing characteristics, nutritional quality and palatability, which could meet consumer demand, and to provide reference for the application and development of leaf use grape in Xinjiang. Mature leaves of 80 grape cultivars (69 table grape cultivars and 11 rootstock cultivars) were used as test materials, 12 indicators related to leaf packing characteristics were measured. Cluster analysis was performed to screen the cultivars which could conform to the packing characteristics by 4 key indicators, including upper cleft depth, flexibility and folding damage level, and vein and dorsal villi. The nutritional and palatability quality of the screened cultivars were evaluated by measuring 5 physicochemical indexes including soluble sugar, soluble protein, tannin, total phenol and total flavonoids. 15 grape cultivars with leaf packing characteristics similar to ‘Thompson Seedless’ were screened out through cluster analysis, such as ‘Rizzamat’, ‘Youwuhe’, ‘Cuixiangbao’, ‘101-14’ and ‘5BB’. The tannin content of 16 cultivars was low, which could meet the requirements of palatability. The content of soluble sugar, soluble protein, total phenol and flavonoids in leaves of the 16 cultivars ranged from 52.46-123.45, 57.09-75.99, 2.20-6.81 and 1.05-4.30 mg/g, respectively. In general, 6 table grape cultivars, ‘Youwuhe’, ‘Rizzamat’, ‘Cuixiangbao’, ‘Zaomanao’, ‘Xinya’ and ‘Wuhecuibao’, and 4 rootstock cultivars, ‘5BB’, ‘101-14’, ‘110R’ and ‘SO4’, could be used as alternative leaf use grape cultivars.
