摘　　要：为研究烤烟上部叶片中纤维素、木质素的含量及其与烟叶质量指标间相关关系,以武陵山区7个县2011—2012年的48个B2F烤烟样品为材料,测定了烟叶中纤维素、木质素的含量,分析了不同年份及品种间的差异。同时,对烟叶纤维素、木质素含量与外观质量、物理特性、常规化学成分、感官质量指标间的相关性进行了研究。结果表明,纤维素、木质素含量在年份、品种间没有显著差异;纤维素含量与外观质量、物理指标、常规化学成分、感官质量中部分指标的相关性呈显著水平;木质素含量与灰色、油分间相关性显著,与其他烟叶质量指标相关性不显著。可见,纤维素、木质素含量在不同年份及品种间差异不显著,纤维素含量与烟叶质量指标间关系密切,木质素含量对烟叶质量影响较小。In order to study cellulose, lignin contents of upper leaf and their correlation with quality indices,48 samples of upper leaf（B2F） were collected from 7 main production counties of Wulingshan Area in 2011 and 2012. The content of cellulose and lignin in tobacco were determined, and the variations of the cellulose,lignin contents in different years and from different varieties were analyzed. The relationships between thecontents of cellulose and lignin and 4 kinds of quality indices（appearance quality, physical property, chemicalcomponents and sensory quality） were analyzed. The results indicated that there were no significant differencesof cellulose and lignin contents among samples collected in different years and from different varieties.Cellulose content had obvious correlation with appearance quality, physical property, chemical componentsand sensory quality. Lignin content had significant correlation with gray and oil, but had no significantcorrelation with other quality indices of the flue- cured tobacco. It concluded that the samples collected indifferent years and from different varieties contained the same quantity of cellulose and lignin. Content ofcellulose was closely related with tobacco quality index, while lignin content had little effect on tobacco quality.
