The respiratory metabolism of apples remains vigorous after harvest, which can accelerate the consumption of sugar, organic acid, and other substances, thus leading to a decline in quality. The influence of postharvest ATP treatment on the changes of quality parameters and sucrose metabolism-related enzyme activity in apples was investigated in this study. The results showed that applying ATP effectively repressed the respiratory rate and weight loss and maintained higher levels of soluble solids content and flesh firmness in apples. In addition, ATP treatment enhanced succinate dehydrogenase, cytochrome oxidase, sucrose phosphate synthase, and sucrose synthase synthesis activities and reduced neutral invertase, acid invertase, and sucrose synthase cleavage activities in apples. These findings suggest that applying ATP after harvest could improve the internal quality of apples by suppressing the respiratory rate and modulating sucrose metabolism.
苹果收获后呼吸代谢仍然旺盛，会加速糖、有机酸等物质的消耗，从而导致品质下降。本研究探讨了采后 ATP 处理对苹果品质参数变化及蔗糖代谢相关酶活性的影响。结果表明，ATP 处理有效抑制了呼吸速率和失重，保持了较高的可溶性固形物含量和果肉硬度。此外，ATP 处理增强了苹果中琥珀酸脱氢酶、细胞色素氧化酶、蔗糖磷酸合酶和蔗糖合酶的合成活性，降低了中性转化酶、酸性转化酶和蔗糖合酶的裂解活性。这些发现表明，采后施用 ATP 可以通过抑制呼吸速率和调节蔗糖代谢来改善苹果的内在品质。
