摘　　要：采用田间试验和气相色谱-质谱联用法分析及电镜扫描,对不同基因型烤烟致香物质含量和腺毛密度差异进行了研究。结果表明,烟叶的致香物质含量与基因型密切相关,不同基因型烤烟致香物质总量存在显著差异,具体表现为兴烟1号>K326>云烟87>贵烟4号;不同基因型烤烟主要类别致香物质含量存在差异,其中云烟87的类西柏烷类、苯丙氨酸类和棕色化产物类致香物质含量较高,而兴烟1号的类胡萝卜素类和新植二烯致香物质含量较高;不同基因型烤烟叶面腺毛密度存在差异,兴烟1号的腺毛密度最大,其次是K326,云烟87的腺毛密度最小。Field experiments,GC/MS and scanning electron microscope technology were used to study differences in aroma substance content and glandular trichome density of different flue-cured tobacco genotypes.Results showed that aroma substance content in tobacco leaves was closely related to its genotype.There was significant difference in total aroma substances content among flue-cured tobacco genotypes as follows： Xingyan1〉K326〉Yunyan87〉Guiyan4.There were significant differences in aroma substance content in major categories of flue-cured tobacco of different genotypes,i.e.content of cembranenoids,phenylalanines,and browning products were higher in Yunyan87,while Xingyan1 had higher content of carotenoids and neoplytadiene.Difference existed in leaf glandular hair density among flue-cured tobacco genotypes,glandular hair density of Xingyan1 was the highest,followed by K326 and Yunyan87.
