Abstract:

To study the effects of bagging and non-bagging management on the quality of short-shoot Fuji apple under double dwarf cultivation mode, four short-shoot Fuji cultivars grafted on M9T337 dwarf rootstock were used as test materials to test the fruit quality and aroma components under different cultivation conditions. The results showed that the contents of soluble solids and total sugar in bagged fruits were lower than those in non-bagged fruits. Malic acid and succinic acid were the main acid components in apples, and different short-shoot Fuji cultivars showed differences. The main aroma components of the four short-shoot Fuji cultivars were esters, accounting for 77.71%-96.49% of the total aroma components. They were typical ester-flavored apple cultivars. In ‘Yanfu 6’, ‘Yiyuan Red’, ‘Miyazaki Short-shoot’ apples, hexyl acetate was the main aroma component of bagged and non-bagged fruits; hexyl acetate was the main aroma component of bagged fruits of ‘Longfu Short-shoot’, while hexyl 2-methyl butyrate was the main aroma component of the non-bagged fruits.

Key words: short-shoot Fuji, double short cultivation, bagged, non-bagged, sugar acid components, aromatic substances
