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 the content of cellulose and lignin in the upper leaves of flue-cured tobacco and their correlations with the quality indexes of tobacco leaves, 48 B2F flue-cured tobacco samples from 7 counties of Wuling Mountain from 2011 to 2012 were used as materials to determine the contents of cellulose, Vegetarian content, analysis of the different years and the differences between varieties. At the same time, the correlation between cellulose, lignin content and appearance quality, physical characteristics, conventional chemical composition, sensory quality index were studied. The results showed that the content of cellulose and lignin had no significant difference between years and varieties. The correlation between cellulose content and appearance quality, physical index, conventional chemical composition and sensory quality was significant. The correlation between lignin content and gray, There was a significant correlation between oil content and other tobacco leaf quality indexes. Visible, cellulose and lignin content in different years and varieties of the difference was not significant, the cellulose content and tobacco quality indicators are closely related to lignin content of tobacco leaf quality has little effect.
