The effects of exogenous ethylene (ETH), 1-methylcyclopropene(1-MCP) and a combined ETH+1-MCP treatments on fruit storage quality and physiological changes were evaluated to investigate the effects of ethephon on the fruit appearance color and internal quality during the ripening process of mangoes Hongguifei. The results showed that compared with the control, both ETH and ETH+1-MCP treatments significantly accelerated the decline in fruit firmness, titratable acid, chlorophyll, flavonoids, total phenolics, and ascorbic acid content, increased cell membrane permeability, and promoted in a* color value, total soluble solids (TSS) in the early stage of storage, and carotenoid. Among the treatments, the ETH+1-MCP group showed the highest level of TSS and carotenoids while 1-MCP group effectively delayed the loss of nutrients and firmness, and inhibited chlorophyll degradation in the fruit peel. Further analysis of the metabolomes of the CK and ethylene treatment groups revealed 140 different metabolites, among which 88 were upregulated and 52 were downregulated. The content of flavonoids in the fruits of the ETH treatment group was significantly lower than that of the control group, indicating that the ETH treatment accelerated the degradation of flavonoids. This study revealed the metabolic mechanism of ETH in promoting the ripening and quality formation of mangoes, which would provide a theoretical basis for in-depth research on the mechanism of post-ripening quality changes in mangoes.
