| 摘 要： | 以丽江雪桃为试验材料，研究其分别经0．5、1．0、1．5、2．0μL／L浓度的1-MCP处理后，放置在（3±1）℃冷藏条件下贮藏27d及货架3d（16＋2）℃的品质变化情况。结果表明，1-MCP处理能够延缓在低温贮藏条件下丽江雪桃的后熟和衰老进程．显著降低果肉褐变指数．较好地保持果实中可滴定酸含量，维持果实硬度，抑制失重率的增加，提高果实品质。其中。以2汕L，L浓度的1-MCP处理对保持果实硬度和可滴定酸含量、抑制失重的效果要好于其他处理，控制果肉褐变以1μL／L浓度的1-MCP处理效果为好。各浓度的1-MCP处理对可溶性固形物含量的变化无明显影响。

| Abstract: | The Lijiang snow peach treated with 0.5, 1.0, 1.5, 2.0 μL/L 1-MCP respectively, and then placed in （3＋1）℃ conditions for 27 days and shelf life for 3 days at （16±2） ℃, the quality changes of snow peach were studied. The results showed that, 1-MCP treatment could delay the ripening and senescence process of Lijiang snow peach during low temperature storage, reduce the flesh browning index significantly, keep the titratable acid content and fruit hardness better, inhibit the increase of weight loss rate, and improve the quality of snow peach. The effects of 2 μL/L 1 -MCP treatment on keeping the fruit firmness, titratable acid content and weight loss were better than the other treatments, but the effect of 1 μL/L 1-MCP treatment on controlling the browning was good. The 1-MCP treatment had no obvious effect on the change of soluble solids content. |
