对非洲崖豆木、白花崖豆木和铁刀木的各类细胞形态进行观察,并测定分析其各类细胞的属性。结果表明:三者的相同之处:以鼓形和圆柱形导管为主,一部分导管端口变窄,单穿孔,导管纹孔为互列纹孔;木纤维细胞略弯曲,纺锤形为主,兼含其他类型,细胞壁甚厚,纹孔小而稀少;木射线为同型,部分木射线的端部细胞略高;轴向薄壁组织串含2~4个细胞,叠生;有分室含晶细胞,通常内含一粒六边形结晶体。不同之处:非洲崖豆木的鼓形导管远少于圆柱形导管且尺寸为3个树种之最大,白花崖豆木和铁刀木的鼓形导管和圆柱形导管的数量略等且含树胶多;铁刀木的部分射线薄壁细胞含晶砂;铁刀木含3~4个细胞的轴向薄壁组织串稀少。
In this paper, we observed the cell morphology of all kinds of cells, such as the African cliff bean, the white flower cliff bean and the iron knife wood. The results show that the three are the same: drum-shaped and cylindrical-shaped catheters are the main part, and some of the catheter ports are narrowed, with single perforation and catheter-like perforation; With other types, the cell wall is very thick, the pits small and sparse; wood ray is the same type, some of the rays of the end cells slightly higher; axial parenchyma tissue containing 2 to 4 cells, superimposed; , Usually contains a hexagonal crystal. The difference is that there are far less drum drums than the cylindrical duct and the size is the largest of the three tree species. The number of drum duct and cylindrical duct of Brassica albiflorus and Cutlass is a little smaller and contains gum And more; iron knife wood part of the ray-parenchyma cells containing sand; iron knife wood containing 3 to 4 cells of the axial thin-walled thinning.
