This study aimed to elucidate the effects of storage temperature on various fruit quality attributes, physiological disorders, and associated metabolites in the 0.5, 3, or 10 °C stored hardy kiwifruit. Peel pitting, which was highest in the 0.5 °C stored fruit, was identified as a chilling injury symptom of hardy kiwifruit. Proline and branched-chain amino acid contents showed higher values at 0.5 °C stored fruit as chilling responses. On the other hand, fruit shriveling and decay were highest in the 10 °C after 5 weeks of storage. The 10 °C storage induced fruit ripening during 3 weeks, but fruit shriveling and decay were severe after 5 weeks of storage. Therefore, storing the 'Autumn Sense' hardy kiwifruit at proper temperatures would be more beneficial, as it alters targeted metabolites and helps reduce the incidence of physiological disorders during cold storage.
本研究旨在阐明不同贮藏温度对 0.5、3 或 10°C 贮藏的硬猕猴桃各项果实品质特性、生理失调及其相关代谢物的影响。在 0.5°C 贮藏的果实中,果皮凹陷被鉴定为硬猕猴桃的冷害症状。脯氨酸和支链氨基酸含量在 0.5°C 贮藏的果实中表现出更高的值,作为冷胁迫反应。另一方面,在贮藏 5 周后,10°C 贮藏的果实出现皱缩和腐烂的比例最高。10°C 贮藏在 3 周内诱导果实成熟,但贮藏 5 周后果实皱缩和腐烂严重。因此,在适当的温度下贮藏“秋感”硬猕猴桃将更为有利,因为它会改变目标代谢物,并有助于减少冷藏过程中生理失调的发生。
