四种槭属植物叶的解剖学研究

Anatomical Studies on the Leaves of Four Species of Acer.L.

采用石蜡切片法和扫描电镜法,对4种槭属植物的叶片进行解剖学研究。结果表明:4种槭属植物的叶片均为典型的异面型叶,气孔皆分布在下表皮,色木槭气孔为无规则型,柠筋槭、假色槭、茶条槭气孔均为不等型;叶片上表皮中只有茶条槭是复表皮,由2层细胞构成;4种植物叶表皮细胞和主脉薄壁组织细胞中皆含晶体。

Based on paraffin sectioning and scanning electron microscope techniques,the leaves of four species of Acer L.were studied.The results showed that the leaves of the four species were all typical back-abdomen type leaves;The stomata of four leaves exists only in lower epidermis,the stomatic of A.mono Maxim.was anomocytic type and that of A.triflorum Kom.and A.pseudosieboldianum（Pax） Kom.and A.ginnala Maxim.were disparity type;The upper epidermis of A.ginnala Maxim.was composed of 2 layers of cells;The epidermis cells and parenchyma cells of main vein phloem of four leaves all contain crystals.
