摘 要：
木果缅茄木材的颜色、花纹和构造特征与大果紫檀相似,一些商家常将其混在大果紫檀原木内进行销售.通过对木果缅茄和大果紫檀木材构造特征进行区分,旨在为质检部门和广大消费者提供两者的鉴别依据.本文从木材颜色与花纹、管孔分布、轴向薄壁组织类型、木射线、木材气味、木粉水浸液荧光等方面,分别对这两种木材进行了区分和比较,总结了6条辨别要点,其中,轴向薄壁组织类型、木射线宽度和高度的差别是鉴别木果缅茄和大果紫檀木材最主要依据.

摘 要：
Because Afzelia xylocarpa has similar color, pattern and structural characteristics of Pterocarpus macrocarpus, it has been mixed up in Pterocarpus macrocarpus logs for sale. The difference of wood structure characteristics between Afzelia xylocarpa and Pterocarpus macrocarpusis aimed at providing the identification basis for quality inspection departments and consumers. From the wood color and pattern, pore distribution,axial parenchyma type,the wood ray,wood odor and fluorescence of wood flour aqueous extraction solution, the two kinds of wood were distinguished and compared, and 6 distinguishing points were summed up in this paper. Among them, the main distinctive points the Afzelia xylocarpa and Pterocarpus macrocarpus are difference of type axial parenchyma and width and height of the wood ray.
