以叶片为产品器官的经济作物,它的叶片栅栏组织与海绵组织的厚度,以及栅栏组织厚度与海绵组织厚度的比值,往往与叶片的品质有一定的关系。栅栏组织内含叶绿体多,专司同化作用,而海绵组织空隙较多,空隙也较大,组织疏松,含叶绿体较少。存在于叶绿体中的胡萝卜素和叶黄素是萜类衍生物,分解后可产生β-紫罗酮等有香味的物质。(?)濑龙男用扫描电镜曾对烤烟烟叶的组织结构进行过深入的研究。蔡石勋、魏治中用石蜡切片法曾研究烟叶结构与品质的关系。

Leaf as a product of the economic crops, its leaf palisade tissue and sponge tissue thickness, and palisade tissue thickness and sponge tissue thickness ratio, often with the leaf quality has a certain relationship. Fence tissue contains more chloroplasts, specializing in the assimilation, while the sponge tissue more voids, voids are larger, loose tissue, containing less chloroplasts. Carotene and lutein present in the chloroplast are terpenoid derivatives that, upon decomposition, produce aroma-causing substances such as beta-ionone. (?) Seto Long male scanning electron microscope had conducted on the structure of flue-cured tobacco in-depth study. Cai Shixun, Wei Zhizhong studied the relationship between tobacco structure and quality by paraffin section method.
