摘　　要：对7个不同基因型烤烟品种在不同肥力水平下烤后中部叶的中性致香物质含量进行了分析。将GC/MS联用仪对烤后烟叶样品进行定性分析,将检出的致香物质分为苯丙氨酸类、棕色化产物、类西柏烷类、类胡萝卜素类4类进行分析,其中韭菜坪二号和秦烟96在不同肥力水平下4类致香物质含量均表现为低肥>中肥>高肥;红花大金元在不同肥力水平下4类致香物质含量均表现为中肥>高肥>低肥,规律明显。低肥水平下,韭菜坪二号中性致香物质含量最高,达到198.71μg/g;红花大金元在中肥和高肥水平下中性致香物质含量均最高,分别达到247.41μg/g和179.82μg/g。对不同基因型烤烟中性致香物质的变异系数进行分析,结果表明,苯丙氨酸类物质的变异受基因型和肥力水平的影响较大,类胡萝卜素类物质含量的变异受基因型和肥力水平的影响较小,而棕色化产物、类西柏烷类和新植二烯等致香物质的含量变异受基因型和肥力水平的影响较稳定。Neutral aroma constituent contents of seven genotypes under different fertility levels were analyzed.Qualitative analysis of these samples was undertaken by using GC/MS.The aroma constituent was detected and divided into four contents,including phenylalanine,browning reaction substance,centranoid,and carotenoid.In JiucaipingⅡ and Qinyan96,the aroma constituent contents varied from high to low in the order as low,middle,and high fertility level.In Dajinyuan,the aroma constituent contents were high in middle fertility level and low in low fertility level.The aroma constituent content of Jiucai-pingⅡ was the highest in lower fertility level and amounted to 198.71 μg/g.The aroma constituent of Dajinyuan was present in high content under middle and high fertility levels,247.41 μg/g and 179.82μg/g respectively.Coefficient of variation of aroma constituents in different genotype flue-cured tobacco was analyzed.The results showed that the variation of phenylalanine was influenced largely by the genotype and fertility level,which were less affected carotenoid and steadily affected browning reaction substance,centranoid,and neoplytadiene.
