摘　　要：In order to study the correlations among quality indexes of tobacco leaf and contents of cellulose and lignin in upper leaves of flue-cured tobacco, 48 B2F flue-cured tobacco samples in seven counties of Wulin mountain area in 2011 and 2012 were used as test materials to measure the contents of cellulose and lignin in tobacco leaves and analyze the differences among varieties and between years. Meanwhile, correlations among contents of cellulose and lignin and appearance quality, physical characteristics, general chemical components and indexes of senso- ry quality were studied. The results showed that the contents of cellulose and lignin had no significant difference among years and varieties. Cellulose content was sig- nificantly correlated with some indexes of appearance qualities, physical indexes, general chemical compositions and sensory qualities. Lignin content was significantly correlated with grayness and oil content but not other quality indexes of tobacco leaf. It could be seen that the differences of cellulose and lignin contents between different years and among varieties were not significant. Cellulose content was closely correlated with quality indexes of tobacco leaf while lignin content had a small effect on tobacco leaf quality.为研究烤烟上部叶片中纤维索、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，对烟叶纤维索、木质索含量与外观质量、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、品种闻没有显著差异；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，纤维索、木质索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。
