摘要
Abstract
The comparative study was conducted for the chemical compositions of four positions of tobacco leaf samples with 3 grades from different tobacco -growing areas .The results showed that there were certain differences in the content of chemical com-positions of tobacco leaves among four positions .The content of reducing sugar was higher in leaf tip and leaf margin , and lower in leaf base;the content of starch was higher in leaf base , and lower in leaf margin;the content of nicotine was higher in leaf margin and leaf base , and lower in leaf center;the content of total nitrogen was higher in leaf tip , and lower in leaf margin and leaf center;the content of potassium was the highest in leaf base;the content of pigment was the highest in leaf base .The content of reducing sugar showed significantly positive correlation at 1%level among four positions of tobacco leaves with 3 grades, and the content of other chemical compositions also had different correlations among four positions .关键词
