摘要

为促进紫檀属木材树种的快速准确识别,分别研究6种紫檀属木材荧光性能的种间和心边材差异。结果显示,6种紫檀属木材种间和心边材的荧光性能差异均为显著;通过荧光光谱检测,综合考虑荧光强度等定量指标和荧光颜色等定性指标,可以准确判定檀香紫檀和染料紫檀,同时将安哥拉紫檀与大果紫檀、刺猬紫檀和非洲紫檀区分。荧光性能标准化定性和定量检测,可以辅助解剖学识别方法,提高紫檀属木材的鉴定水平。

Abstract

To assist rapid and accurate identification of Pterocarpus species, interspecies differences and differences between heartwood and sapwood in wood fluorescence properties of 6 Pterocarpus species were studied.Results showed that the interspecies differences and differences between heartwood and sapwood of wood fluorescence properties of Pterocarpus species were significant. Through fluorescence spectrum detection,the quantitative indexes such as fluorescence intensity and the qualitative indexes such as fluorescence color are comprehensively considered. P. santalinus and P. tincrorius could be accurately determined. At the same time, P. angolensis could be discriminated from P. marsupium, P. erinaceus and P. soyauxii.Qualitative and quantitative standardization detection of wood fluorescence properties could be an assistant method to improve identification level of Pterocarpus species.
