摘要
对银桦 (Grevillearobusta)次生木质部导管分子进行了观察研究。在银桦次生木质部导管分子中存在着许多不同的样式 ,分别对其进行了描述 ,并从导管分子个体发育与系统发育的角度进行了讨论。银桦导管分子中还存在着特殊的样式 ,如具三个单穿孔的导管以及导管分子侧壁上存在明显的皱褶 。
The vessel elements of secondary xylem in Grevillea robusta is observed and studied in this paper. The result shows that there are various patterns of vessel elements in Grevillea robusta. the ontogeny and phylogenesis of vessel elements in Grevillea robusta was discussed. Special patterns of vessel elements in Grevillea robusta were described and discussed, such as three simple perforation in one vessel element and the distinctness gauffer in the side wall of vessel elements in Grevillea robusta.
