The establishment of agroforestry systems (AFS) is a consistent strategy to integrate sustainable supply of wood, food and environmental services in a single land plot. Teak ( Tectona grandis Linn. F.) is an interesting option for the tree component in AFS, though there is a lack of information on its potential. This study aimed to characterize the quality of teak wood produced in an AFS regarding its technological characteristics and best end uses. Wood was sampled from a multi-stratified AFS located in the midwestern region of Rondônia state, Brazil, more specifically in a formerly deforested area of Amazon rainforest. The AFS is composed of double-ranked perennial crops and the forest component has growing space of 5.0 × 2.5 m. Physical-mechanical properties of teak wood were assessed and the results indicated its medium to high dimensional stability along with mechanical performance very close to that determined for wood from either homogeneous plantations or natural forests. Specific strength was significantly higher than some tropical wood species with higher densities. Teak wood from the AFS reached the minimum requirements for structural applications, with suitable properties to be used in the manufacture of decks, partitions and, residential flooring.

在亚马逊雨林地区建立的多层次农林业系统中种植的树木中柚木（Tectona grandis）木材的质量评估

建立农林业系统（AFS）是在单一土地上整合木材，粮食和环境服务的可持续供应的一致战略。柚木（Tectona grandis Linn。F.）是AFS中树木组件的一个有趣选择，尽管缺乏有关其潜力的信息。这项研究旨在就AFS生产的柚木的技术特性和最佳最终用途来表征其质量。木材取材于位于巴西朗多尼亚州中西部地区的多层次AFS，更具体地说是在亚马逊雨林的先前被砍伐的森林中。AFS由多年生双季作物组成，森林部分的生长空间为5.0×2.5 m。对柚木的物理机械性能进行了评估，结果表明柚木具有中等至高的尺寸稳定性，其机械性能非常接近于均质人工林或天然林的木材。比强度显着高于某些密度较高的热带木材。AFS生产的柚木达到了结构应用的最低要求，并具有适合用于制造甲板，隔断和住宅地板的特性。
