摘　　要：取皖南3种不同质地土壤生产的烤后烟叶样品进行中性香气物质和常规化学成分含量测定,并进行单料烟感官评吸鉴定。结果表明,砂壤土各部位烟叶的类胡萝卜素降解产物、糖类降解产物含量、中部叶的西柏烷类降解产物茄酮含量、下部叶的苯丙氨酸裂解产物含量水平相对较高。常规化学成分中总糖含量和烟碱含量均较高,糖碱比适宜,评吸认为其感官质量优良,焦甜香突出。水稻土下部和中部叶类胡萝卜素降解产物含量、中部叶茄酮含量偏低,而上部叶苯丙氨酸裂解产物和类胡萝卜素降解产物较高,总糖含量较低,上部叶烟碱和总氮含量偏高,糖碱比偏低,焦甜香不显著,上部叶虽香气量大,但劲头偏大。砂壤土烟叶一般变现为中上部烟叶各类香气物质含量偏低,总糖含量较高,但含氮化合物含量偏低,糖碱比偏高,评吸认为焦甜香弱,烟叶香气量偏小。3 typical tobacco soils with different textures in south Anhui were selected to investigate the differences in the contents of aroma components and regular compounds in flue-cured tobacco leaves and the differences in the sensory evaluation on aroma quality. The results showed that tobacco leaves from alluvial sandy soil had high levels of carotenoid catabolites and sugar catabolites in all stalk positions, and high levels of solanone in middle leaves and high levels of phenylalanine catabolites in low leaves. Both sugar and nicotine contents were high and the ratio of sugar to nicotine was suitable. The sensory quality was good with rich sweet aroma. For clayey paddy soil, the contents of carotenoid catabolites were low in low and middle leaves, solanone was also low in middle leaves, while phenylalanine and carotenoid catabolites were high in up leaves. The content of sugar was low, while the contents of nicotine and total nitrogen were high in up leaves, which led to lower sugar nicotine ratio, The sweet aroma was not significant and the smoke was strong for up leaves. For silty sand soil, the neutral aroma components were generally at low level for middle and up leaves. The sugar content was high, while the nicotine content was low, and the ratio of sugar to nicotine was high. Sensory evaluation showed the samples had week sweet aroma and lack of aroma.
