| 摘 要： | 研究表明，连香树叶为异面叶，气孔仅分布于下表皮，栅栏组织发达，茎的次生木质部为散孔材，导管端壁倾斜，具梯状复穿孔，木薄壁细胞甚少，表明连香树在进化中是较原始的树种、老根的次生皮层和射线薄壁细胞都分布有较多的颗粒物质。

| Abstract: | The study shows that the leaf of Cercidiphyllum japonicum is of dorsi-ventral leaf, with developed palisade tissue, and the stomata only scattering over the lower epidemis of the leaf. The scondary xylem of the stem is that of diffuse-porous wood. The vessed end wall, applanate and slopping,is ladder-shaped compound fenestrated. The wood parenchyma is rare. All these indicate that Cercidiphyllm japonicum is a more primitive species in evolution. There pellet matter distributed in the secondary cortex of old roots, and in the ray parenchyma. |
