Abstract: 【OBJECTIVE】Study of the storage effect and relationship between physiological variations and chilling injury in soft Peach of south at different temperature, and research the suitable storage condition of soft Peach of south.【METHOD】Different temperature (25℃、0℃、2℃、5℃) were used to store the soft Peach of south, observed and measured the biochemical and physiological changes such as respiratory, conductivity, hardness, the content of MDA, TSS, total acid, sugar and Vc, et al. 【RESULTS】The results indicated that at 0℃ peach can normally post-ripe , and had normal flavor when stored for 28d. But for the condition of 2℃ and 5℃, the different degree of chilling injury all happened when stored for 7d. Additionally, when took out the peach that stored for 28d at 0℃ and then stored at 25℃, it could normally soft in the shelf-life of 3d.【CONCLUSION】For the soft Peach of south , the optimal storage condition was stored for 28d at 0℃; The shelf-life was 3d when took out the peach that stored for 28d at 0℃ and then stored at 25℃; The peach could happened the different degree of chilling injury stored at 2℃ and 5℃.
