摘　　要： 利用光学显微镜和扫描电镜技术,对白木香茎次生木质部结构进行了解剖研究．结果 表明,茎材横切面为散孔材,生长轮不明显,导管分子单穿孔板,木材分子非叠生,绝大多 数射线为异形Ⅲ型管孔排列方式多为茎向复管孔或管孔团,具有内函韧皮部．还从解剖学的角 度对白木香次生木质部的构造特点进行了讨论． Anatomical structure ofAquilaria sinensis wood was studied in this paper by means of light microscope and scanning electron microscope. The stem wood ofAquilaria sinensis is diffuse-porous and the growth rings are not obvious in it. The vessel elements are simple perforation plates. The elements of wood are not storied. Most of the wood rays are heterogeneous III. Most of pore distribution are pore chains or pore clusters. There are included phloems in the secondary xylem of Aquilaria sinensis. In addition, the characteristics of the secondary xylem of Aquilaria sinensis were discussed in this paper based on wood anatomy.
