The objective of this study was to evaluate the interaction between controlled atmosphere (CA), CA+1-methylcyclopropene (1-MCP) and dynamic controlled atmosphere monitored by respiratory quotient (DCA-RQ) with three fruit maturity stages at harvest (early harvest date, optimal harvest date and late harvest date) on 'Galaxy' apple metabolism and quality after harvest and 9months storage plus 7days of shelf life at 20°C. Fruit stored under dynamic controlled atmosphere monitored by respiratory quotient 1.3 (DCA-RQ 1.3) showed lower ethylene production, respiration rate, mealiness and higher flesh firmness in comparison to CA stored fruit, but did not differ from those treated with 1-MCP. The dynamic controlled atmosphere monitored by respiratory quotient 1.5 (DCA-RQ 1.5) increased the acetaldehyde, ethanol and ethyl acetate concentration, regardless of the fruit maturity at harvest. The storage of 'Galaxy' apple under DCA-RQ 1.3 is efficient in keeping quality regardless of the maturity stage at harvest.
本研究的目的是评估三种果实成熟度（早采期、最佳采期和晚采期）下，控制气氛（CA）、CA+1-甲基环丙烯（1-MCP）和呼吸商监测的动态控制气氛（DCA-RQ）与“银河”苹果代谢和采后贮藏 9 个月加 20°C 货架期 7 天的相互作用。与 CA 贮藏的果实相比，呼吸商监测的动态控制气氛 1.3（DCA-RQ 1.3）贮藏的果实乙烯生成量、呼吸速率、粉质感和果肉硬度较低，但与 1-MCP 处理的果实无差异。呼吸商监测的动态控制气氛 1.5（DCA-RQ 1.5）无论采果成熟度如何，均增加了乙醛、乙醇和乙酸乙酯的浓度。无论采果成熟度如何，DCA-RQ 1.3 贮藏均能有效保持“银河”苹果的品质。
