Analysis of Trichome Density and the Content of Glandular Secretion on Different Flue-Cured Tobacco Leaves

Article Preview

Abstract:

To clarify the relationship between the glandular density and the glandular trichome secretion content of different varieties of flue-cured tobacco,the trichome density of 5 kinds of flue-cured tobacco species was analyzed by electron microscope,and glandular secretion was analyzed by GC/MS.The results showed that:the trichome density of flue-cured tobacco is not proportional with the content of glandular secretions,and the morphology of glandular trichome were approximately same in five tobacco varieties.The content of cembrenoids are the highest in the glandular trichome secretion components of flue-cured tobacco,which is the main ingredient.Through regulating metabolism terpenoids to improve diterpene content is the key element to improve the content of tobacco glandular secretions.
