The research was conducted to measure the effect of temperature on respiratory and quality characteristics of 'Tsugaru' apple(Malus domestica Borkh) during storage at 4C, 10C and 20C. Respiration rate of the apple just after harvest was 7.57 mL CO/kg/h at 20C. It was decreased rapidly and was 2.86 mL CO/kg/h after storage for 45 days at 20C. The apples showed the highest ethylene production rate at 10C and 20C after 14 days, and at 4C after 28 days during storage. Weight of the apple was reduced by 2.9% after 120 days at 4C and by 6.1% after 45 days at 20C. Color difference of peel and pH increased with the temperatures but titratable acidity and flesh firmness showed the reverse trends during storage. According to the subjective quality test, it could be suggested that the shelf-life of the apple is 86 days at 4C, 65 days at 10C and 37 days at 20C, respectively.
