烟叶的经济性状,均有其植物学基础。烟叶表面的腺毛,对烟叶的化学特性有着重要的影响。因此,对烤烟烟叶腺毛的研究,具有一定的经济价值。近年来,关于烟叶腺毛的数量分布,以及烟叶腺毛数量与石油醚提取物之间关系的研究,已经受到重视。由于近代显微技术的进步,有机化学和生物化学的发展,对于烟叶腺毛的生理功能及其化学成分的认识日趋深入,研究烟叶腺毛的经济价值也逐渐明确。烟草研究者一般认为,烟叶的芳香油来源于叶片表面的腺毛及腺毛的分泌物。腺毛的数量多,芳香油的含量就多,香气则好;反之,烟叶香气差。因此,他们把烟叶腺毛的数量作为评价烟叶品质的一个参数。M.K.Chak-raborty 和 J.A.Weybrew 研究叶片毛状物中 The economic traits of tobacco have their botany basis. Glandular hairs on the surface of tobacco leaves have an important effect on the chemical properties of tobacco leaves. Therefore, the study of flue-cured tobacco glandular hairs has certain economic value. In recent years, studies on the quantitative distribution of glandular trichomes and the relationship between the number of glandular trichomes and the petroleum ether extract of tobacco have drawn attention. Due to the progress of modern microscopy, the development of organic chemistry and biochemistry, the understanding of the physiological function of tobacco glandular trichome and its chemical composition is becoming more and more in-depth. The economic value of studying the glandular trichome of tobacco is also gradually clarified. Tobacco researchers generally believe that the fragrance of tobacco leaves from the leaves of the glandular hair and glandular hair secretions. A large number of glandular hair, the content of aromatic oil is more, the aroma is good; Conversely, the aroma of tobacco is poor. Therefore, they used the number of tobacco glandular hairs as a parameter to evaluate the quality of tobacco. M.K. Chak-Raborty and J.A. Wyethbrew studied leaf trichomes
