摘　　要：本文通过扫描电子显微镜 ,对东北地区蒿属 (Artemisia)植物 ,莳萝蒿组(A .sect.AbsinthiumDC) ,艾蒿组 (Sect .AbrotanumBess) ,艾组 (Sect.Artemisia) ,龙蒿组 (Sect.DracumculusBess) ,牡蒿组 (Sect .latiobusY .R .Ling) 36种成熟代表植物叶表皮形态学特征进行了详尽的比较研究。其中表皮细胞大小、形状不等。下表皮均有气孔器。气孔器的形状大多数为园形、卵园形或椭圆形。气孔类型为不规则型、不等细胞型、辐射细胞型等。大多数植物叶表皮具有表皮细胞毛。这些微形态特征在组间存在着某种差异 ,具有一定的分类和生态学意义。The morphological structure of leaf epiderm from 36 representative spcie in of Sect. Absintnium DC, Sect. Abrotanum Bess, Sect. Artemisia, Sect. Dracumculus Bess , and Sect. Latiobus Y.R. Ling from Artemisa were obserred in detail using scanning electron microscope, All the cpidermal cells varied in size and shape. The hypodermis had stoma. The shapes of the stoma were round.ovate and ovai. The types of stoma were anomocytac stoma. Anisocytac stoma and actinocytic stoma. The epiedrm of most plants had epidermal cell hain hair. The deffernce in these microstructural characters among groups may be of importance in taxonymy and ecology.
