Abstract

Abstract: Changes in the physiology and quality of apple fruits during cold storage were examined to reveal the storage characteristics of different apple varieties. ‘Yueshuai’, ‘Wangshanhong’, ‘Yueyanghong’ and ‘Qiufuhong’ apples were stored at (0 ± 0.5) ℃ and 90%–95% relative humidity. The respiration intensity, firmness, total soluble solids contents, titratable acid contents and VC contents, weight loss, PPO activity and POD activity of apples were measured and correlated with storage characteristics. The results showed that ‘Yueshuai’ apples had the lowest respiration intensity and enzymatic activities, but they accelerated the occurrence of respiration peak and deteriorated quickly after storage for more than 84 days. ‘Yue yanghong’ apples had lower respiration intensity and enzymatic activities and maintained the best quality and flavor compared with other varieties during storage. The respiration peak of ‘Wangshanhong’ and ‘Qiufuhong’ apples appeared later, and their qualities were retained well during storage. In conclusion, ‘Yueshuai’ apples had the shortest storage life while ‘Yueyanghong’, ‘Wangshanhong’ and ‘Qiufuhong’ apples could be stored for longer time, and ‘Yueyanghong’ fruit retained the best quality after storage.

Key words: apples, cold storage, physiology quality, changes
