摘要
采用香型指数和香气指数的评价方法,研究了几种栽培技术和烤房类型对K326香型风格和香气品质特征的影响。结果表明,在与烤烟香型指数和香气指数相关的香气成分中,栽培技术对棕榈酸甲酯、二氢猕猴桃内酯、异戊酸和苯甲醇含量影响较大,变异系数均大于20%;对大马酮、茄酮和法尼基丙酮含量影响中等,变异系数均在10%～20%之间;对糠醛、二氢-β紫罗兰醇、苯乙醛和巨豆三烯酮含量影响较小,变异系数均低于10%。不同烤房类型对棕榈酸甲酯、二氢猕猴桃内酯和苯甲醇含量影响较大,变异系数均大于20%;对糠醛、茄酮和异戊酸含量影响中等,变异系数均在10%～20%之间;对大马酮、二氢-β紫罗兰醇、法尼基丙酮、巨豆三烯酮和苯乙醛含量影响较小,变异系数均低于10%。但不同栽培技术和烤房类型对烤烟香型指数、香气指数(包括AI、A值和B值)的影响均较小,变异系数均低于10%,因此,在黔南烟区生态条件下,烤烟香型风格和香气底韵是相对稳定的,并不会因栽培和烘烤技术的差异发生明显改变。
The study analyzed the effect of various cultural practices and barn type on aroma style and quality of K326 basing on the indices of aroma and aroma style. Results showed that cultural practices had large effects on methyl palmitate, dihydroactinolide, isovaleric acid and benzil alcohol, with coefficients of variation exceeding 20%; moderate effects on damascone, solanone, farnesylactite, with coefficients of variation as 10%-20%; and small effects on furfural, dihydro-13-ionol, hyacinthin and megastigmatrienone, with coefficients of variation below 10%. Barn type had large effects on methyl palmitate, dihydroactinolide and benzil alcohol, with coefficients of variation exceeding 20%; moderate effects on furfural, solanone and isovaleric acid, with coefficients of variation as 10%-20%; and small effects on damascone, dihydro-[3-ionol, famesylactite, megastigmatrienone and hyacinthin, with coefficients of variation below 10%. However, both cultural practices and barn type had little effects on indices of aroma （including figure A and B） and aroma type, with coeffient of variation below 10%. It is concluded that under the climatic conditions of Qiannan, Guizhou Province, the style of aroma type and aroma of flue-cured tobacco was relatively stable and not considerably changed by cultural or curing practices.
