Abstract: The effects of 1-MCP and modified atmosphere packaging (MAP) on the fresh-keeping and quality of ‘Huahong’ apples were investigated during cold storage (0 ℃) in this study. The results indicated that, compared with control group, 1-MCP or MAP treatment significantly inhibited ethylene production and respiration rate, delayed the decrease of fruit firmness, soluble solid content and titratable acid, and inhibited the increase of L value and cell membrane permeability. No CO2 injury was found in‘Huahong’apple packaged in 0.02 mm PE and 0.04 mm PVC bags, which suggests that‘Huahong’apple is resistant to carbon dioxide injury. The storage life of ‘Huahong’ apple was prolonged by different treatments in the following order: 1-MCP＞0.04 mm PVC bags＞0.02 mm PE bags＞control. However, the quality of‘Huahong’apple was maintained in the following order: 0.04 mm PVC bags＞1-MCP＞0.02 mm PE bags＞control.

Key words: ‘Huahong’apple, 1-methylcyclopropene (1-MCP), modified atmosphere packaging (MAP), quality, fresh-keeping effect
