摘要 巴西是世界上最大的木炭生产国，这种材料的很大一部分仍然来自原生森林，特别是来自塞拉多生物群落，该生物群落受到人为退化的严重影响。控制木炭生产的需要增加了木炭鉴定的需求，但关于碳化引起的解剖学改变的信息很少。本文分析了来自五种巴西树种（紫花黄檀、多叶马钱子、圭亚那貘、Vochysia tucanorum 和 Pouteria torta）的新鲜和烧焦木材样品。描述了木材和木炭的解剖特征，并对木材和木炭的主要解剖特征的测量结果进行了统计比较。观察到了细微的变化：碳化后最明显的变化是切向容器直径的减小；射线（宽度）收缩仅发生在某些个体中。本研究支持烧焦木材的鉴定，希望有助于木炭生产的控制以及古环境和考古植物学研究。
Summary Brazil is the world’s largest producer of charcoal and a great part of this material still comes from native forests – especially from the cerrado biome, which is highly impacted by anthropogenic degradation. The need to control charcoal production increases the demand of charcoal identifi cation, but there is little information about the anatomical modifications due to carbonization. In this paper, fresh and charred wood samples from five Brazilian species were analyzed (Dalbergia violacea , Stryphnodendron polyphyllum, Tapirira guianensis, Vochysia tucanorum, and Pouteria torta). anatomical characters were described and measurements of the main anatomical features of wood and charcoal were statistically compared. Minor modifications were observed: reduction of tangential vessel diameter was the most evident change after carbonization; shrinkage of rays (in width) occurred only in some individuals. The present study supports the identification of charred woods, hopefully contributing to the control of charcoal production, and to palaeoenvironmental and archaeobotanical studies.
