Abstract

The objective of this paper was identifed anatomically and describe wood species marketed as charcoal in the region of Papanduva, SC, southern Brazil, to provide technical information to help in identification of species from the Atlantic Forest biome. Packages of 3 to 10 kg of charcoal were purchased, a pre-selection from more similar pieces was performed, macro and microscopic images were obtained for posterior anatomical description and material identification. Mislabeling was found in some charcoal packages, including genus, from both angiosperm and gymnosperm groups. Samples were found in decreasing frequency order, from the genera Eucalyptus/Corymbia, Ocotea/Nectandra, Acacia, Pinus, Araucaria, Alchornea, Casearia, Cedrela, Eugenia, Hieronyma, Ilex, Schinus and Zanthoxyllum. In gymnosperms, it was possible to verify growth rings distinct, with differences in cell wall thickness of tracheid and resin canals in pinus. In angiosperms, diffuse porosity was more frequent, with highlight to semiring porous in genus Cedrela . The presence of tyloses was predominant in genus Eucalyptus/Corymbia ; septate fibers were characteristics for genus Ocotea/Nectandra. Simple perforate plate and alternate intervessel pits were predominant, with exception of genus Ilex with scalariform perforation plate and opposite intervessel pits. Secretory canals were observed in genus Zanthoxyllum. The predominance of eucalyptus from planted forests was observed, but the presence of araucaria, which is on the list of endangered species, indicated the importance of better supervision and training for awareness of producers and local traders.

巴西南部圣卡塔琳娜州帕潘杜瓦地区销售的木炭的解剖和鉴定。

本文的目的是解剖鉴定和描述巴西南部南卡罗来纳州帕潘杜瓦地区作为木炭销售的木材物种，以提供技术信息，帮助鉴定大西洋森林生物群系的物种。购买3至10公斤的木炭包，从更相似的碎片中进行预选，获得宏观和微观图像，用于后部解剖描述和材料鉴定。在被子植物群和裸子植物群的一些木炭包装中，包括属，都发现了错误的标记。桉树属(Eucalyptus/Corymbia)、Ocotea/Nectandra、金合欢(Acacia)、松属(Pinus)、Araucaria、Alchornea、Casearia、Cedrela、Eugenia、Hieronyma、Ilex、Schinus和Zanthoxyllum的分布频率依次递减。在裸子植物中，有可能验证生长环的不同，松木管胞和树脂管的细胞壁厚度不同。被子植物中弥漫性孔隙多，以松属以半环状孔为主。桉属中以tylose为主;ococtea /Nectandra属的特征是纤维分离。除具有鳞片状穿孔板和相对的血管间凹外，绿菖蒲属植物以单孔板和互生血管间凹为主。花椒属植物中有分泌管。观察到种植森林的桉树占多数，但在濒危物种名单上的桉树的存在表明，必须加强监督和培训，以提高生产者和当地贸易商的认识。

期刊介绍： Revista Floresta admits articles of scientific contribution in Forest Science, in the areas of Nature Conservation, Economy and Forest Policy, Forest Management, Silviculture and Wood Technology. The main task is to promote and divulgate the development of Forest Science in Brazil and in the world. Articles published in Revista Floresta are under total responsibility of the authors, who are aware that they are original studies. It remains implicit that articles were not submitted for publication to any other divulgation media. It remains explicit the agreement of authors to norms of the journal and, along the development of their work, the observance of ethic aspects and respect of the current copyright legislation.
