Fruit Storage and Quality Evaluation of Six Kinds of Actinidia deliciosa

Abstract:

To select new Actinidia varieties with good storage and flavor quality, the quality and storability of three wild varieties 'kvf54', 'kvf6' and 'Xinmei' of A. deliciosa and three cultivated varieties 'Qinmei', 'Huamei' and 'Xuxiang' were compared and analyzed. The results showed that under room temperature and 1℃ storage, the hardness of 'kvf54' and 'Xuxiang' decreased in a similar trend, which was better than other varieties, and 'kvf54' had the highest content of vitamin C (V_C). However, under the same storage conditions, the soluble solids content of 'Xinmei' accumulated the fastest, the starch and titratable acid contents were the least, showing poor storage performance. Therefore, compared with other varieties, 'kvf54' had better storability, higher contents of V_C and sugar, so it was a high-quality variety that could be used to breed new storage-tolerant varieties.
