Abstract: In this study, three treatments such as, controlled atmosphere（80% N₂+15% CO₂+5% O₂）, 3 ppm ozone, negative ion treatment, was conducted in Hanjiang cherry storage under ice temperature. The preservative effects of the three treatments was evaluated by measuring the changes of vitamin C, Brix value, organic acid, water loss rate and decay rate during storage. The results showed that the controlled atmosphere treatment and negative ion treatment could effectively prolong the storage time. When stored for 20 days, the decay rate was only about 22% and the fruit quality could be maintained. The loss of vitamin C, soluble solids and organic acids in Hanjiang cherry fruits were delayed. Ozone treatment could also prolong the storage time and reduce the rotting rate of fruit, but the color of fruit epidermis was easy to change and affect the sensory and quality of the fruits. It suggested that negative ion treatment and controlled atmosphere（80% N₂+15% CO₂+5% O₂） treatment could be the ideal storage methods of Hanjiang cherry.
