Correlation between Chemical Components in Flue-cured Tobacco and Burning Velocity

YU Jian-jun et al(National Tobacco Cultivation & Physiology & Biochemistry Research Center,Henan Agricultural University,Zhengzhou,Henan 450002)  
Studies on correlation,step regression and path analysis between chemical components in flue-cured tobacco from different producing area in Henan province and burning velocity of flue-cured tobacco were researched in this paper.The results of correlation analysis showed that K and K/CL were related to burning velocity positively,Cl was related to burning velocity negatively.The results of step regression analysis and path analysis indicated that the direct effect of seven chemical components was the number of the ratio of total sugar to nicotinenicotineKtotal nitrogen the ratio of total sugar to reducing sugarCl reducing sugar.When the new cigarette blending will be developed,K and Cl should be taken into consideration first,then to comprehensively consider the rest of chemical components.
