Individual and combined effects of postharvest 1-methylcylcopropene (1-MCP) treatment and controlled atmosphere (CA) storage on quality changes of 'Hongro' apples during storage were investigated by two-way analysis of variance. Apples were harvested at commercial maturity, treated with 1 μLL-¹ 1-MCP, and stored under refrigerated air or CA conditions for 4 months at 0℃.At 2-month intervals, fruit were removed from storage and put on the shelf for 7 days at 20℃to simulate marketing at room temperature. Postharvest 1-MCP treatment and CA storage significantly reduced respiration and ethylene production. Titratable acidity, flesh firmness, and texture ratings were retained higher by 1-MCP treatment and CA storage, while greasiness on the fruit skin was effectively suppressed by the treatments. However, additional effects from the combined treatment of 1-MCP and CA were slight. Storage potential of 'Hongro' apples seemed to be extended to 4 months by the 1-MCP treatment. Although effects of 1-MCP treatment was not so great as CA storage, postharvest application of the chemical could substitute CA storage for 'Hongro' apples programmed to be stored for 4 months plus 7 day shelf life at room temperature.
