圆籽荷属木材构造的研究

山茶科圆籽荷属(Apterospefma)木材为散孔材至半环孔材,管孔细,射线细,薄壁组织肉眼下不见,密度中偏大,纹理直,结构细。微观构造:在导管相互间纹孔式对列夏导管分子穿孔梯状的横栅24—77条,射线异形Ⅰ型。射线与导管问纹孔为较大不规则形单纹孔,对列,薄壁组织星散.1—2个细胞。

STUDIES ON THE WOOD STRUCTURE OF APTEROSPERMA CHANG

The gross features of the wood of genus Apterosperma, Theaceae being diffuse-porous wood or semi-diffuse-pourous wood, pores minute, rays fine, parenchyma not seen by the naked eye, density middle, rather heavy, grains straight to interlocked, texture fine. The microtissues of wood of this genus are the bordered pits between vessels opposite, the number of the bars of scalariform perforation plate 24-77, rays heterogeneous, type I, the pits between rays and vessels irregular, large simple pits, opposite, parenchyma diffuse, consists of 1-2 cells.
