摘　　要：研究了烤烟不同基因型间质体色素含量差异及与烟叶化学成分的关系。结果表明,不同烤烟基因型烟叶中质体色素含量差异显著。相关分析结果发现,叶绿素a仅与总糖呈显著性正相关;叶绿素b与烟碱呈显著性负相关,与总氮含量呈极显著性负相关;类胡萝卜素与总糖呈显著性负相关,但与烟碱和总氮含量呈显著性正相关。通径分析结果表明,叶绿素a和叶绿素b对总糖、烟碱和总氮的直接影响最大,类胡萝卜素对总糖、烟碱和总氮的间接影响最大。由此可见,通过对烤烟质体色素代谢进行合理调控,有利于协调烤烟化学成分,提高烟叶的可用性。The relationship between the difference of plastid pigment contents and chemical components in different flue-cured tobacco varieties were analyzed. The results showed that the content of plastid pigments had significant differences in different flue-cured tobacco varieties. Correlation analysis revealed that chloropbyll-a only showed positive correlation with total sugar. Chlorophyll b showed negative correlation with nicotine, and showed significant negative correlation with total nitrogen. Carotenoids showed negative correlation with total sugar, but showed positive correlation with nicotine and total nitrogen. The results on path analysis revealed that total sugar, nicotine, total nitrogen were directly affected mostly by chlorophyll-a and chlorophyll-b and indirectly affected mostly by carotenoids. Therefore, if flue-cured plastid pigment metabolism was controlled reasonably, it would be helpful to coordinate the chemical composition of flue-cured tobacco leaves and improve the usability.
