| 摘 要： | 【目的】研究不同温度贮藏模式对南方‘湖景蜜露’水蜜桃贮藏生理及货架期品质的影响，探索适宜的贮藏温度，为南方软质型水蜜桃贮藏技术的发展与应用提供理论指导。【方法】设置不同贮藏温度25℃、5℃、2℃和0℃，测定桃果实贮藏期间的呼吸强度、相对电导率、丙二醛（MDA）、硬度、可溶性固形物（TSS）、总酸以及Vc等各项生理生化指标。【结果】0℃贮藏与25℃、5℃和2℃相比，能较好保持‘湖景蜜露’桃果实整个贮藏期间TSS和TA的含量，显著降低果肉硬度的下降，明显抑制果实贮藏过程中呼吸强度的增加，推迟呼吸峰出现的时间，延缓桃果实膜脂过氧化的发生，果肉未出现糠化等冷害症状，表现出较好的贮藏效果。同时经0℃贮藏28 d出库后，桃果实在常温3 d的货架期内，果肉可以正常软化，食用品质未发生明显劣变。【结论】南方软质型水蜜桃较适宜的贮藏条件为0℃贮藏28 d，出库后放置在20℃条件下货架期约为3d。

| 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℃. |
