Resumo: The objective of this study was to determine the chemical composition, basic density and tracheids morphological parameters of the wood of Cupressus lusitanica aiming to verify its suitability for cellulosic pulp production. Discs were collected from three 16-year-old trees to determine chemical, physical and morphological characteristics. The morphology of the tracheids was evaluated in the annual rings corresponding to the ages of 4, 7, 10, 13 and 16 years. The pulp quality parameters were calculated from the tracheid parameters. The chemical composition indicated low ash and extractive contents (0.27 and 2.13%, respectively), but high lignin content (32.52%). The basic density (0.375 g cm-3) was smaller than other species of softwood used for pulp production. The mean values of tracheids dimensions observed were 2.41 mm of length, 31.40 μm of width; 25.15 μm of lumen diameter and 3.12 μm of wall thickness, which tended to increase in values with increasing age. In general, C. lusitanica wood presents good technological characteristics for pulp and paper production, especially for the observed quality morphological index.

Foram utilizadas três árvores, com 16 anos, das quais extraíram-se discos que foram empregados na caracterização química, física e morfológica da madeira. A morfologia dos traqueídeos foi avaliada nos anéis correspondentes as idades 4, 7, 10, 13 e 16 anos. A partir dos parâmetros dos traqueídeos, calcularam-se os indicadores de qualidade da polpa. Foram observados baixos teores de cinzas e extrativos (0,27 e 2,13%, respectivamente), porém alto teor de lignina (32,52%). A densidade básica (0,375 g.cm-3) foi menor que de outras espécies de coníferas utilizadas para produção de celulose. Os traqueídeos apresentaram valores médios de 2,41 mm de comprimento; 31,40 µm de largura; 25,15 µm de diâmetro do lúmen e 3,12 µm de espessura de parede, que tenderam a uma elevação nos valores com o aumento da idade. De maneira geral, a madeira de C. lusitanica apresenta boas características tecnológicas para produção de celulose e papel, especialmente pelos índices morfológicos de qualidade observados.Embrapa Florestas2020-01-13info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/189410.4336/2020.pfb.40e201901894Pesquisa Florestal Brasileira; v. 40 (2020)Pesquisa Florestal Brasileira; Vol. 40 (2020)1983-26051809-3647reponame:Pesquisa Florestal Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/1894/914https://creativecommons.org/licenses/by-nc-nd/4.0info:eu-repo/semantics/openAccessVivian, Magnos AlanCorrêa, RonanModes, Karina SoaresCaetano, Ana PaulaPedrazzi, CristianeDobner Júnior, Mário2020-08-27T21:25:03Zoai:pfb.cnpf.embrapa.br/pfb:article/1894Revistahttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/PUBhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/oaipfb@embrapa.br || revista.pfb@gmail.com || patricia.mattos@embrapa.br1983-26051809-3647opendoar:2020-08-27T21:25:03Pesquisa Florestal Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
