The results showed that the superficial scald was mainly detected during shelf-life at 20 after 200 days cold storage，and the lower the storage temperature，the worse the superficial scald disease. The core browning index of fruit stored at–1 and 5 ℃ was obviously higher than that at 0 ℃ and 1.5 ℃. The fruit firmness and soluble solids content（SSC）kept well when stored at 0 and 1.5 ℃，as well as the taste and flavor. For the fruit stored at 5 ，the fruit firmness was the lowest and the decay rate was the highest. While for that stored at–1 ，the fruit firmness and S
