4种常见仿沉香木的木材构造特征比较

Comparison on wood structure characteristics of Aquilaria sinensis and four common confusable species

对沉香木及其制品真伪鉴定、确定其濒危保护等级对于海关口岸执法极为重要。本文对鹰香木(Aetoxylon sympetalum)、五桠果(Dillenia indica)、可乐豆(Colophospermum mopane)和非洲螺穗木(Spirostachys africana)等4种常见仿沉香木与白木香(Aquilaria sinensis)的木材宏观和微观构造特征进行比较研究,结果表明4种木材在木材颜色、管孔类型、轴向薄壁组织、韧皮部组织、木射线构造上与白木香存在差异,沉香木岛屿式内涵韧皮部,为沉香属木材的重要鉴别特征,可为沉香初步鉴别鉴定提供参考。

To identify the authenticity of agarwood and its products and determine the endangered species protection level is very important for Customs to enforce relevant laws and regulations at ports. The characteristics of the woods of Aquilaria sinensis and 4 common confusable species such as Aetoxylon sympetalum,Dillenia indica,Colophospermum mopane and Spirostachys africana were observed and compared at macroscopic and microscopic levels. There were differences in color,pore arrangement pattern,axial parenchyma,phloem tissue and wood ray,and the island phloem of Aquilaria sinensis was an important identification trait to identify Aquilaria wood,which would provide reference for the preliminary identification of agarwood.
