Dendrological Characterization as Inspection Resources of Caatinga Wood Market

ABSTRACT This study aimed to distinguish five native forest species of the Caatinga Biome from the exotic invasive algaroba (Prosopis juliflora (Sw.) DC.), considering dendrologic characteristics of bark and wood, in order of providing subsidies for the inspection of the wood market in this Biome. The native species studied were jurema-preta (Mimosa tenuiflora (Willd.) Poir.), angico branco (Anadenanthera colubrina var. colubrina (Vell.) Brenan), angico vermelho (Anadenanthera colubrina var. cebil (Gris.) Alts.), aroeira (Myracrodruon urundeuva Allem) and braúna-do-sertão (Schinopsis brasiliensis Engl.). Studied species were recognized using dendrology identification records, containing characteristics of bark, heartwood and sapwood coloration; and the organoleptic proprieties like color, smell and taste, used for safe wood logs identification. The macroscopic characteristics, organized in dichotomous key, allowed the differentiation among the species, available in logs, during inspection.

摘要 本研究旨在通过树皮与木材的树木学（dendrology）特征，区分卡廷加生物群区（Caatinga Biome）的5种本土森林树种与外来入侵树种牧豆树（Prosopis juliflora (Sw.) DC.），以期为该生物群区的木材市场查验提供技术依据。本次研究涉及的本土树种包括黑朱雷木（Mimosa tenuiflora (Willd.) Poir.）、白安吉科（Anadenanthera colubrina var. colubrina (Vell.) Brenan）、红安吉科（Anadenanthera colubrina var. cebil (Gris.) Alts.）、阿罗埃拉树（Myracrodruon urundeuva Allem.）以及塞唐布劳纳（Schinopsis brasiliensis Engl.）。研究通过树木学鉴定记录对受试树种进行确认，相关记录涵盖树皮、心材与边材的色泽特征，以及用于安全识别原木的感官属性，包括色泽、气味与滋味。以二歧检索表（dichotomous key）整理的宏观形态特征，可在木材查验过程中实现对在售原木的物种区分。
