摘　　要：为探究营养生长期叶喷水溶硅对楼葱品质的影响,采用气相色谱-离子迁移谱(GC-IMS)技术对楼葱挥发性化合物进行检测分析。结果表明:楼葱假茎、管状叶分别检测出64种和67种挥发性化合物,其中假茎中鉴定出有效物质共38种,管状叶中鉴定出有效物质共33种,喷施400倍的水溶硅能够提高假茎中呈花果香气(格蓬酯、辛酸乙酯等)以及香辛气味(二烯丙基二硫、二丙基三硫醚等)的挥发性化合物累积量,且能提高管状叶中呈花香果香的挥发性化合物的丰度。因此,通过外源水溶硅的喷施,可提升楼葱特征性挥发性化合物的含量,为加强楼葱不同组织部位定向利用提供了理论依据。In order to explore the effect of leaf spraying water-soluble silicon during nutritional growth period on Allium fistulosum L.var.viviparum Makino quality,this study adopted gas chromatography ionmobility spectrometry(GC-IMS)technology,detected and analyzed the volatile compounds of Allium fistulosum L.var.viviparum Makino.Results showed that 64 and 67 volatile compounds were detected in pseudo stem and tubular leaves,respectively.Among them,38 effective substances were identified in pseudo stem and 33 effective substances were identified in tubular leaves.Spraying 400 times water-soluble silicon could increase the accumulation quantities of volatile compounds with floral and fruity aroma(tsugbonate,ethyl octanoate,etc.)and spicy odor(diallyl disulfide,dipropyl trisulfide,etc.)in pseudo stem,and increase the abundance of volatile compounds with floral and fruity aroma in tubular leaves.Therefore,spraying exogenous water-soluble silicon could increase the content of characteristic volatile compounds in Allium fistulosum L.var.viviparum Makino,and then provided theoretical basis for strengthening directive utilization of different tissue parts in Allium fistulosum L.var.viviparum Makino.
