摘　　要：为进一步挖掘四川、山东产区烟叶致香物质含量特色,本研究基于51份烤烟种质,在四川、山东两产区开展了烟叶8类致香物质含量检测分析比较工作。结果显示,整体上看,四川多酚类、叶绿素降解物绝对和相对含量高于山东产区,苯丙氨酸降解物、高级脂肪酸、多元酸绝对和相对含量低于山东产区;从不同基因型上看,四川92.2%以上种质多酚类、叶绿素降解物的绝对和相对含量高于山东产区,76.5%以上种质苯丙氨酸降解物、高级脂肪酸和多元酸的绝对和相对含量低于山东产区,进一步印证了两产区致香物质含量在整体上表现出的特点;51份种质中,四川产区有76.5%烤烟种质预测具有清香型风格倾向,在山东产区有90.2%烤烟种质预测具有中间香型风格倾向,多酚类和叶绿素降解物含量较山东产区高可能是四川清香型风格烟叶的重要物质基础;苯丙氨酸降解物、高级脂肪酸和多元酸含量较四川产区高可能是山东中间香型风格烟叶的重要物质基础。基因型和生态条件对香型指数均有较大影响,生态条件影响更大。To further explore the aroma component characteristics of Sichuan and Shandong tobacco leaves,eight types of aroma components were determined and their content characteristics were analyzed using the leaf samples of 51 flue-cured tobacco varieties planted in both Sichuan and Shandong.The results showed that,on the whole,the absolute and relative contents of polyphenols and chlorophyll degradation products in Sichuan were higher than those in Shandong tobacco leaves,while the absolute and relative contents of phenylalanine degradation products,higher fatty acids,and polybasic acids were the opposite.From the perspective of different genotypes,the absolute and relative contents of polyphenols and chlorophyll degradation products of more than 92.2%of germplasms planted in Sichuan was higher than that planted in Shandong.The absolute and relative contents of phenylalanine degradation products,higher fatty acids and polyacids of more than 76.5%of germplasms were lower than that planted in Shandong.This result further confirmed the characteristics of the aroma substance content in tobacco leaves of the two production areas as a whole.Among the 51 germplasms,76.5%of the flue-cured tobacco germplasms in the Sichuan production area were predicted to have a fragrance style tendency,and 90.2%in the Shandong production area were predicted to have an intermediate flavor style tendency.The contents of polyphenols and chlorophyll degradation products were higher than that of Shandong tobacco leaves,which may be the important material basis of Sichuan fragrance style tobacco.The contents of alanine degradation products,higher fatty acids and polybasic acids were higher than that in Sichuan tobacco leaves,which may be the important material basis of Shandong middle-flavor tobacco.Both genotype and ecological conditions have a significant impact on the fragrance index,and ecological conditions have a greater impact than genotypes.
