摘　　要： 利用扫描电子显微镜对黑龙江绣线菊属(Spiraea)15种植物成熟叶片表皮形态结构进行比较研究。结果表明:叶表皮细胞呈不规则形和多边形,垂周壁式样为平直弓形、深波状或浅波状;多数植物不具有表皮毛,少数植物上下表皮均具表皮毛或上表皮具有表皮毛;气孔器为无规则型、轮列型和不典型的辐射型且均位于叶的下表皮;气孔外拱盖内缘平滑、近平滑、波状和浅波状;气孔外拱盖单层或双层;保卫细胞两极无"T"型加厚。为该属植物的系统演化关系和植物分类学提供形态学理论依据。 A study on morphology structure of epidermis of the genus Spiraea in Heilongjiang province was conducted with scanning clectron microscope （SEM）. The result shows that epidermal cells are irregular-shaped and polygonal, the anticlinal wall are strait-arched, sinuated, sinuolate; most of species do not have trichomes, only a little species have trichomes on upper epidermal cells or lower epidermis cells and only the ceils of upper epidermal have trichomes; Stomatal apparatus are located in the lower epidermis, all of them are anomocytic, cyclocytic and atypical actinocytic ; the inner margin of the outer stomatal rim is glabrous, candida, sinuous and sinuolate ; uni-layered outer stomatal rim or double layer; having not T-pieces at the polar region of guard cells, having notably T-pieces at the polar of guard ceils. The result provides morphological basis of phylogeny and taxonomic significance for the Spiraea plants of Heilongiiang province.
