Study on Anatomical Structure of Aquilaria Sinensis Wood

Anatomical structure of Aquilaria sinensis wood was studied in this paper by means of light microscope and scanning electron microscope. The stem wood of Aquilaria 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.
