摘　　要：【目的】研究控制库尔勒香梨采后贮藏期间萼端黑斑病发病的钙和l-甲基环丙烯(1-MCP)正交组合方式。【方法】采前喷施0.014%、0.017%、0.020%钙肥和采后1.0、2.0、3.0μL/L 1-MCP处理的正交组合,分析各处理对贮期果实品质和萼端黑斑病发病率的影响。【结果】低浓度的采前喷钙结合采后1-MCP处理,能使果实保持较高的硬度和鲜亮的果皮色泽。采前给树体喷钙,能增强采后果实抵御萼端黑斑病等病害发生的能力。【结论】(0.017%液钙+2.0μL/L 1-MCP)处理能使果实保持较高的硬度和较好的果皮色泽;(0.014%液钙+2.0μL/L 1-MCP)处理能明显降低贮藏期间果实的萼端黑斑率及其腐烂率,对果实萼端黑斑病的抑制效果最好;(0.020%液钙+1.0μL/L 1-MCP)处理能使果实保持细胞膜的完整性。【Objective】The orthogonal combination of Calcium and 1-MCP were found to control the incidence of calyx tip black spot in korla pear during postharvest storage.【Method】The effects of different treatments on fruit quality and incidence of calyx terminal black spot were studied by using the orthogonal combination of 0.014%,0.017%and 0.020%calcium fertilizer before harvest and 1.0,2.0 and 3.0μ/L 1-MCP treatments after harvest.【Result】Low concentration of calcium before harvest combined with 1-mcp treatment after harvest could make the fruit maintain a higher hardness and bright skin color.And spraying calcium into the tree body before harvest could enhance the postharvest fruit's ability to resist the occurrence of calyx tip black spot and other diseases.【Conclusion】(0.017%liquid calcium+2.0μL/L 1-MCP)treatment could maintain higher hardness and better skin color.(0.014%liquid calcium+2.0μL/L 1-MCP)treatment could significantly reduce the rate of calyx tip dark spot and its rate of decay during storage,and had the best inhibitory effect on calyx tip black spot.(0.020%liquid calcium+1.0μ/L 1-MCP)treatment could maintain the integrity of fruit cell membrane.
