摘要:

【目的】研究氯化钙和1-MCP对采后西州蜜甜瓜贮藏品质的影响。【方法】以鲜食西州蜜甜瓜为试材,分别采用1.5%CaCl2、1 μL/L的1-甲基环丙烯和1.5%CaCl2、1 μL/L1-甲基环丙烯复合处理,以无处理的西州蜜甜瓜作为对照组CK。分析其在贮藏过程中的腐烂率、失重率、呼吸强度、硬度、可溶性固形物、原果胶、POD酶、CAT酶的变化。【结果】氯化钙与1-MCP均能抑制西州蜜甜瓜的呼吸强度、其中氯化钙与1-MCP复合处理还推迟了果实的呼吸跃变,在第28 d,氯化钙与1-MCP复合处理组果实硬度较CK组提高了83.3%,原果胶含量较CK增加了7.5 mg/(g·FW),可溶性固形物含量较CK增加了20.4%,POD酶、CAT酶活性较CK分别降低了42.9%和64.6%。【结论】氯化钙与1-MCP复合处理更好的抑制了果实的呼吸强度、原果胶物质的分解,延缓了西州蜜甜瓜的软化,保持了果实的贮藏品质。

Abstract:

【Objective】 To investigate the effects of calcium chloride and 1-MCP on the storage quality of postharvest Xizhou honeydew melon.【Methods】 Fresh Xizhou honeydew melon was used as test materials, with 1.5% CaCl2 and 1.5% CaCl2 respectively μL/L 1-methylcyclopropene and 1.5% CaCl2, 1 μL/L 1-methylcyclopropene compound treatment, with the untreated Xizhou melon as the control group.Meanwhile, the changes of decay rate, weight loss rate, respiratory intensity, hardness, soluble solids, protopectin, pod enzyme and CAT enzyme during storage were analyzed.【Results】 Both calcium chloride and 1-MCP could inhibit the respiratory intensity of Xizhou melon, and the combined treatment of calcium chloride and 1-MCP also delayed the respiratory jump of fruit. On the 28th day, the fruit hardness of the combined treatment of calcium chloride and 1-MCP was increased by 83.3% and the original pectin content was increased by 7.5 mg/(g·FW) compared with CK group. Compared with CK, the content of soluble solid increased by 20.4%, and the activities of POD enzyme and CAT enzyme decreased by 42.9% and 64.6%, respectively.【Conclusion】 The combined treatment of calcium chloride and 1-MCP can better inhibit the respiratory intensity of fruit and the decomposition of protopectin, delay the softening of Xizhou melon and maintain the fruit storage quality.

Key words: Xizhou melon; calcium chloride; 1-MCP
