摘要: 对12种鸢尾叶片的表皮特征进行了观察和研究,结果表明野鸢尾、单花鸢尾、北陵鸢尾3种鸢尾各自的上下表皮细胞的形状及气孔密度等有明显区别,而其余9种鸢尾叶片各自上下表皮形态均无明显差异。12种鸢尾的气孔类型均属于横列型,且气孔均是随机分布,气孔保卫细胞的长轴与叶脉平行,叶脉处无气孔分布。不同种鸢尾之间叶片表皮特征具有显著差异,可为鸢尾属植物的分类提供依据。

Abstract: The micro-morphology characters of leaf epidermis of 12 species of Iris were examined under light microscope(LM). It is considerd that there are obvious differences in the characters of leaf upper and lower epidermis of I. dichotoma Pall., I. uniflora Pall. and I. typhifolia Kitagawa of themselves, but there are not differences among the other 9 species. The type of stomata of 12 species of Iris is diacytic type, stomata is randomly distributed. Guard cells are parallel to leaf veins where no stomata distribute. There are obvious differences among 12 species of Iris in the micro-morphology characters of leaf epidermis, which will provide bases for Iris classification.

Key words: Iris, leaf, epidermis cell, stomata
