摘要: 采用香型指數(shù)和香氣指數(shù)的評價(jià)方法，研究了幾種栽培技術(shù)和烤房類型對K326 香型風(fēng)格和香氣品質(zhì)特征的影響,。結(jié)果表明,，在與烤煙香型指數(shù)和香氣指數(shù)相關(guān)的香氣成分中，栽培技術(shù)對棕櫚酸甲酯,、二氫獼猴桃內(nèi)酯,、異戊酸和苯甲醇含量影響較大,，變異系數(shù)均大于20%,；對大馬酮,、茄酮和法尼基丙酮含量影響中等，變異系數(shù)均在10%～20%之間,；對糠醛,、二氫-β紫羅蘭醇,、苯乙醛和巨豆三烯酮含量影響較小，變異系數(shù)均低于10%,。不同烤房類型對棕櫚酸甲酯,、二氫獼猴桃內(nèi)酯和苯甲醇含量影響較大，變異系數(shù)均大于20%,；對糠醛、茄酮和異戊酸含量影響中等,，變異系數(shù)均在10%～20%之間,；對大馬酮、二氫-β紫羅蘭醇,、法尼基丙酮,、巨豆三烯酮和苯乙醛含量影響較小，變異系數(shù)均低于10%,。但不同栽培技術(shù)和烤房類型對烤煙香型指數(shù),、香氣指數(shù)（包括AI、A 值和B 值）的影響均較小,，變異系數(shù)均低于10%,，因此，在黔南煙區(qū)生態(tài)條件下,，烤煙香型風(fēng)格和香氣底韻是相對穩(wěn)定的,，并不會因栽培和烘烤技術(shù)的差異發(fā)生明顯改變。Abstract: 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-β-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-β-ionol, farnesylactite, 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.
