摘要
该文探讨1-甲基环丙烯(1-MCP)处理对"香蜜"甜杨桃果实采后生理和贮藏品质的影响。采后"香蜜"甜杨桃果实用0.6μL/L的1-MCP处理12 h后,在(15±1)℃、相对湿度90%下贮藏。贮藏期间测定果实呼吸强度、细胞膜相对渗透率、果皮叶绿素和类胡萝卜素含量、果实硬度、可溶性固形物和可滴定酸含量、果实好果率、失重率及感官品质等指标的变化。结果表明:与对照果实相比,1-MCP处理能有效降低杨桃果实的呼吸强度和呼吸峰值,抑制果实外观颜色转变,保持较高的果实硬度和可滴定酸含量,延缓果实细胞膜相对渗透率升高,减少果实失重和腐烂。经1-MCP处理的果实在(15±1)℃、相对湿度90%下贮藏20 d时的好果率为78%,而对照果实只有63%。因此认为,0.6μL/L 1-MCP处理可延缓采后‘香蜜’甜杨桃果实成熟衰老和保持果实贮藏品质。
