摘　　要：在光学显微镜下观察槲寄生与4种寄主植物的叶表皮特征。结果表明:(1)槲寄生叶为等面叶而4种寄主植物叶均为异面叶;(2)槲寄生的表皮细胞与气孔长度大约是4种寄主植物的2倍;(3)生态适应性方面,气孔密度与槲寄生的寄生量存在正相关,气孔长度与寄生量负相关。In this paper,leaf epidermal characters in Viscum coloratum and four host trees were observed under light microscope.Our results indicate that：（1）Viscum coloratum has isolateral leaf and four host trees have bifacial leaf;（2）epidermis cells and stomata length of Viscum coloratum are as two times as that of four host trees;（3）in case of ecological adaptability,stomata density and length of host plants have positive and negative relationship with the quantity of Viscum coloratum respectively.
