中文摘要: 为延长无花果采后的贮藏品质，以丝路红玉无花果为试验材料，采用不同厚度聚乙烯（polyethylene，PE）保鲜膜复合1-甲基环丙烯（1-methylcyclopropene，1-MCP）熏蒸处理无花果，通过测定果实理化指标、营养品质等相关指标，探究其低温贮藏的效果。结果表明：PE保鲜膜处理可以维持持续的低氧环境，有效抑制果实颜色、硬度的劣变，降低失重率、腐烂率，其中以0.05 mm厚度的保鲜膜效果最佳。而1.5 μL/L的1-MCP与0.05 mm PE保鲜膜复合处理组不仅抑制了无花果颜色的氧化褐变和后熟转红，同时也抑制了果实营养物质的劣变，有效提高了无花果的贮藏品质。
Abstract:Figs of the variety Silu Hongyu were treated with polyethylene （PE）films of different thicknesses in combination with 1-methylcyclopropene（1-MCP）fumigation，and then the storage quality of post-harvest figs was studied.The effects of low temperature storage on figs were investigated by measuring the physical and chemical indexes and the nutritional quality of the fruits.The results showed that PE film could maintain a continuous low oxygen environment to inhibit the deterioration of fruit color and hardness and reduce the weight loss rate and decay rate.In particular，the 0.05 mm-thick film showed the best fresh-keeping performance.The combination of 1.5 μL/L 1-MCP and 0.05 mm PE film inhibited not only the oxidative browning and postharvest reddening of fruits but also the deterioration of fruit nutrients，which effectively improved the storage quality of figs.
