After harvest, ‘Sangjudungsi’ persimmon (Diospyros kaki Thunb.) fruit quickly soften and develop physiological disorders during cold storage. The objective of this study was to evaluate the effectiveness of 1-methylcyclopropene (1-MCP) and aminoethoxyvinylglycine (AVG) treatments on fruit quality attributes and antioxidant metabolites in ‘Sangjudungsi’ persimmon fruit stored at 0.5 °C and 95% relative humidity over a 3-month period. The treatments caused a reduction in weight loss; in the middle of the cold storage, the soluble solids content was higher with the AVG treatment than with the 1-MCP treatment. Both treatments reduced the incidence and severity of peel blackening and fruit softening, whereas fruit decay was only affected by AVG. The content of total phenolic compounds was lower with AVG than with 1-MCP or in the untreated control during the same period. At the end of cold storage, the AVG treatment resulted in a greater total flavonoid and total antioxidant activity and a higher reduced glutathione level than with 1-MCP or in the untreated control. AVG likely evoked the least physiological and biochemical responses in persimmons, according to the results of a normalized heatmap matrix system. Correlation coefficient networking results showed that 1-MCP and AVG caused differential correlation responses between the fruit quality variables and targeted metabolites during cold storage. Overall, the results indicated that treatment of cold-stored persimmons with 1-MCP and AVG likely reduced the incidence of physiological disorders, although antioxidant metabolites were relatively less affected by both regulators.

柿子收成后，柿子柿冷藏期间，果实迅速变软并发生生理异常。这项研究的目的是评估1-甲基环丙烯（1-MCP）和氨基乙氧基乙烯基甘氨酸（AVG）处理对'Sangjudungsi'柿果在0.5°C和95％相对湿度下储存的水果品质属性和抗氧化剂代谢产物的有效性。 3个月的时间。这些治疗使体重减轻减少了。在冷藏期间，AVG处理的可溶性固形物含量高于1-MCP处理的可溶性固形物含量。两种处理都降低了果皮变黑和水果变软的发生率和严重程度，而水果腐烂仅受AVG影响。在同一时期，AVG的总酚类化合物含量低于1-MCP或未经处理的对照组。在冷藏结束时，与1-MCP或未处理的对照组相比，AVG处理可产生更高的总类黄酮和总抗氧化剂活性，并具有更高的降低的谷胱甘肽水平。根据归一化热图矩阵系统的结果，AVG可能在柿子中引起最少的生理和生化反应。相关系数网络化结果表明，1-MCP和AVG导致冷藏期间果实品质变量与目标代谢产物之间的差异相关响应。总体而言，结果表明，尽管抗氧化剂代谢物受两种调节剂的影响相对较小，但使用1-MCP和AVG处理冷柿饼可能会降低生理疾病的发生率。
