摘　　要：以‘布兰瑞克’和‘玛斯义陶芬’无花果为试材,研究1-MCP(1.5μL·L^(-1))处理对低温货架期((2±1)℃、RH90%~100%)果实色差、硬度、失重率、可滴定酸、可溶性固形物、呼吸强度的影响,并利用气相色谱—质谱(gas chromatography-mass spectrometry,GC-MS)技术分析了1-MCP处理前后果实挥发性物质含量和种类的变化。结果表明:1-MCP熏蒸处理有效保持了果实鲜亮的色泽,延缓果实硬度、可滴定酸和可溶性固形物的下降,1-MCP处理对两品种失重率的抑制效果无显著差异,对‘玛斯义陶芬’具有更为明显的呼吸高峰延迟作用。新鲜的‘布兰瑞克’和‘玛斯义陶芬’无花果分别检测到4类18种和5类35种挥发性物质。醛类是两个品种无花果主要的挥发性物质,1-MCP处理显著地刺激了‘布兰瑞克’中己醛、2-己烯醛、庚醛和苯乙醛等醛类物质的生成,促进了‘玛斯义陶芬’中己醛、2-己烯醛、壬醛的生成。With the experimental material of‘Branswick’and‘Masiyitaofen’fig,the effects of 1-MCP(1.5μL·L^(-1))treatment on fruit color,hardness,weight loss rate,titratable acid,total soluble solid and respiratory intensity of fig fruit during shelf life at(2±1)℃(RH 90%~100%)were studied.In addition,the effects of 1-MCP on relative content and type of volatile components of postharvest fig were analyzed by gas chromatography-mass spectrometry(GC-MS).Compared with the control group,1-MCP fumigation treatment effectively maintained bright color of fruit peel,delayed the decrease of hardness of fruits,titratable acid and total soluble solid.The 1-MCP treatment had no significant difference in the inhibition effect on weight loss rate of the two varieties,but had a more obvious delayed effect on the respiratory peak of'Masitovine'.Fresh‘Branswick’and‘Masiyitaofen’fruits were respectively detected eighteen volatile compounds categorized into four different chemical classes,and thirty-five compounds into five classes.Aldehydes were the main volatile compounds in two varieties of figs.After fumigation of 1-MCP,the production of aldehydes including hexanal,2-hexenal,heptaldehyde,and phenylacetaldehyde of‘Branswick’and hexanal,2-hexenal and nonanal of‘Masiyitaofen’fig fruits were significantly stimulated.
