利用光学显微镜和扫描电子显微镜对木犀榄族(Oleeae)5属14种植物的叶表皮微形态特征进行了观察,结果表明:(1)叶表皮细胞形状有无规则形和多边形两种;下表皮腺点的数目远远大于上表皮,流苏树上表皮细胞没有腺点;叶下表皮有气孔器,形状为圆形、椭圆形;气孔器均为不规则型;气孔器外围角质层有放射状、条状、环状、颗粒状等多种类型;(2)气孔器和叶表皮细胞许多特征具有明显的种间差异,可以作为种间鉴定的重要依据;(3)叶表皮微形态结构上的许多共同特征,表明木犀榄族植物是单独一自然类群.上述特征可为木犀榄族植物属及物种的划分与鉴定、系统演化关系的探讨等提供参考.

Leaf epidermal micromorphology of 14 species representing 5 genera of Oleeae (Oleaceae) from China were examined using light microscopy (LM) and scanning electron microscopy (SEM).The results indiated that:(1) The shapes of leaf epidermal cells in Oleeae were usually irregular or polygonal;The number of glandular opaque spot in abaxial epidermis was larger than that of adaxial epidermis.Chionanthus retusus had not gland in adaxial epidermis;Only the abaxial epidermis had stomata.The shapes of the stomata were round oval.The type of stomatal apparatuses in Oleeae were all irregular.The cuticular membrane periphery of stomatal apparatus was radiated,strip,circularity and granulated;(2) The characters of stomatal apparatuse and leaf epidermal cells had obvious differences among species,so they could serve as one of the criteria to identify species of Oleeae;(3) There were many common characteristics on leaf epidermal micromorphology,so we suggest Oleeae is a separate natural group.These characters provided references for division and identification of genera and species,systematic evolution relationships of Oleeae.
