摘　　要：对云南、贵州两省C3F烟叶55个样品的常规化学成分及评吸质量进行了相关分析及Q型聚类分析.烟叶化学成分与评吸质量评价指标之间的相关分析表明:香气质、劲头、杂气、细腻度、刺激性、干燥感、甜度及余味与烟叶主要化学成分相关性显著,其中香气质与还原糖极显著正相关;劲头与烟碱、总氮极显著正相关,与糖碱比极显著负相关;杂气、细腻度与还原糖极显著正相关;刺激性、干燥感及甜度与总糖、还原糖、糖碱比极显著正相关;余味与还原糖、糖碱比极显著正相关,与烟碱极显著负相关.香气量、透发性、浓度、成团性与主要化学成分相关性不显著.化学成分聚类法与评吸结果聚类法相结合可用于配方调整以及需要的某一原料不足或缺乏时进行替代烟叶选取.The correlativity between the main chemical components and smoking quality of 55 tobacco leaf samples coming from Yunnan and Guizhou province was analyzed by using the maths＇ statistical methods. The results of correlative analysis were as follows. The correlative analysis between the main chemical components and smoking quality showed that aroma quality, physiological strength, offensive odor, exquisite degree, irritation, dryness, sweetness and remaining flavor were significantly correlated with the main chemical components. The aroma quality had extremely significant and positive effect on reducing sugar; The physiological strength had extremely significant and positive effect on nicotine and total nitrogen, but had significantly negative effect on the ratio of reducing sugar to nicotine; The offensive odor and exquisite degree had extremely significant and positive effect on reducing sugar; The irritation, dryness and sweetness had extreme significant positive effect on total sugar, reducing sugar and the ratio of reducing sugar to nicotine; The remaining flavor had extremely significant and positive effect on reducing sugar and the ratio of reducing sugar to nicotine, but had extremly significant and negative effect on nicotine. The method combined cluster analysis based on chemical components with cluster analysis based on on smoking quality could be used to select substitute tobacco leaves.
