摘要
Abstract
To investigate the differences in physical and chemical indicators of tobacco stems from different parts of the'Honghuadajinyuan'variety in the Dali tobacco-growing area,a comparative analysis of these indicators was conducted.The results showed that in terms of physical indicators,the tobacco stem length and content in middle part were significantly higher than those in other parts;the filling value of cut stems in upper part was significantly better than that in the middle and lower parts.In terms of chemical compositions,the content of total sugar and reducing sugar in middle part were the highest;the content of nicotine,total chlorine,and chlorine in upper part were the highest;the difference between total sugar and reducing sugar,sugar-to-nicotine ratio,nitrogen-to-nicotine ratio,and potassium-to-chlorine ratio in middle part were the best;and the potassium content in lower part was significantly higher than that in other parts.Correlation analysis showed that equilibrium moisture content was significantly positively correlated with total nitrogen content.Among them,equilibrium moisture content in upper part was positively correlated with nicotine content,and equilibrium moisture content in middle part was positively correlated with potassium and chlorine content.In addition,the filling value of cut stems in lower part was positively correlated with reducing sugar and total nitrogen content,while the filling value of cut stems in all parts was negatively correlated with the difference between total sugar and reducing sugar,sugar-to-nicotine ratio,and nitrogen-to-nicotine ratio.关键词
