摘　　要：为明确江西产区烤烟香气成分特征及其关键气象影响因子,比较了我国5个不同中间香及浓香型产区烤烟香气物质含量,明确了江西烤烟香气成分特征,并分析了江西省烤烟香气成分特征的区域差异及与气象因子的关系。结果表明:(1)江西烤烟中性香气物质含量较低,但巨豆三烯酮含量较高、在中性香气物质中所占比例最高且代谢转化最强;(2)江西烤烟中各巨豆三烯酮异构体含量及其总量存在较大的产地差异,其异构体含量及总量均与大田中后期的气象因子密切相关,尤其是成熟期的均温。总的来看,巨豆三烯酮含量较高是江西烤烟重要的香气成分特征,成熟期均温是影响江西烤烟巨豆三烯酮含量及其产地差异的关键气象因子。To clarify aroma component characteristics of Jiangxi tobacco leaves and key meteorological impact factors,aroma component contents of flue-cured tobacco from five different pure-sweetness type or burnt-sweetness type tobacco-planting areas in China were compared,and regional differences of characteristic aroma components in flue-cured tobacco and their association with meteorological factors in Jiangxi were analyzed in this study.The results showed that:(1)Megastigmatrienone content was higher in Jiangxi tobacco leaves,which accounted for the highest proportion of neutral aroma components and had the strongest metabolic formation from 3-oxo-α-ionol to megastigmatrienone,although neutral aroma component content in Jiangxi tobacco leaves was lower than that in other areas.(2)There were obvious regional differences in the contents of megastigmatrienone isomers and their total amount in Jiangxi tobacco leaves,which were closely associated with meteorological factors during mid-late stages of growth in the field,especially with the average temperature at mature stage.Therefore,high content of megastigmatrienone is an important aroma component characteristic of Jiangxi tobacco leaves,and average temperature at mature stage is a key meteorological factor impacting on formation and accumulation of megastigmatrienone in tobacco leaves and regional differences of megastigmatrienone contents in Jiangxi.
