摘  要：
对不同产区的3个等级4个区位烟叶样品的化学成分进行了系统的比较分析,探讨了不同产区的4个区位烟叶化学成分的相似性。结果表明:不同区位烟叶中化学成分含量有一定的差异,还原糖含量叶缘、叶尖较高,叶基低;淀粉叶基较高,叶缘较低;烟碱中下部烟叶叶缘、叶基较高,叶中较低;总氮叶尖较高,叶缘、叶中较低;钾离子含量叶基最高;色素成分含量叶基最高。3个等级的还原糖含量在4个区位之间均达到极显著正相关,其他成分在4个区位之间也存在不同的相关性。

摘  要：
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 compositions 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.
