Abstract: 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 the contents of cellulose and lignin and four kinds of quality indices (appearance quality, physical property, chemical components and sensory quality) were analyzed. The results indicated that there were no significant differences of cellulose and lignin contents between samples collected in different years and from different varieties. Cellulose content had obvious correlation with appearance quality, physical property, chemical components and sensory quality. Lignin content had significant correlation with gray and oil, but had no significant correlation with other quality indices of the flue-cured tobacco. We can conclude that the samples collected in different years and from different varieties contained the same quantity of cellulose and lignin. Content of cellulose was closely related with tobacco quality index, while lignin content had little effect on tobacco quality.
