Abstract:

The cell wall matter components of B2F、C3F、X2F in flue-cured tobacco of high quality tobacco development zone “Jin Panxi”,including Pan Zhihua and Liang Shan were determined.The cell wall matter components and the quality of tobacco in Si Chuan province were evaluated and the partial correlation analysis of the obtained data was carried out. The results showed that: (1)the cell wall matter components of B2F、C3F、X2F in flue-cured tobacco in Si Chuan province didn’t appear remarkable. The contents of cell wall substance, total cellulose, lignin , pectin, hemicellulose and a-cellulose were in the ranges of 24%～35%,10%～16%,0.5%～4%,5%～9%,2%～5% and 5%～9% , respectively. (2)The total cell wall matter components in Si chuan province were negatively correlated with body significantly, tensile strength and the quality of smoke flavor, but positively correlated with equilibrium moisture content significantly. Total cellulose components of tobacco leaves were positively correlated with body significantly and thickness. The hemicellulose components of tobacco leaves were positively correlated with body significantly. The a- cellulose components of tobacco leaves were positively correlated with structure significantly, but positively correlated with body significantly.
