Resumo:  This study aimed to evaluate wood physical properties of Pinus patula, aged 38, from a forest stand located in Machipanda, central region of Mozambique. Determination of physical properties, such as basic specific gravity, shrinkage, and moisture content of wood in the pith-bark followed the recommendations of the Panamerican Standard - COPANT. Results showed statistically significant differences at significance level of 5%, in the radial direction for the shrinkage coefficient in the pith-bark. Radial and tangential shrinkage values were 6.06 and 8.80% in juvenile wood and 6.18 and 8.65% in adult wood, respectively, with anisotropy coefficient of 1.43 for juvenile wood and 2.44 for adult wood. Pinus patula growing in Inhamacari forest shows stable wood at age 38. It can be used for structural purposes and for manufacture of joinery and furniture.

A determinação das propriedades físicas como a massa especifica básica, retratibilidade e umidade da madeira, no sentido medula-casca, seguiram as recomendações da Norma Panamericana - COPANT. Os resultados evidenciaram diferença estatística, ao nível de 5% de significância, no sentido radial para o coeficiente de retratibilidade. Os valores de retratibilidade foram de 6,06 e 8,80% no lenho juvenil e 6,18 e 8,65% no lenho adulto no sentido radial e tangencial, respectivamente, com coeficiente de anisotropia de 1,43 no lenho juvenil e 2,44 no lenho adulto. A madeira de Pinus patula, plantado na floresta de Inhamacari, apresenta uma madeira estável aos 38 anos de idade, que pode ser aplicada para fins estruturais e para a fabricação de artigos de carpintaria e móveis.Embrapa Florestas2015-09-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/77110.4336/2015.pfb.35.83.771Pesquisa Florestal Brasileira; v. 35 n. 83 (2015): jul./set.; 285-292Pesquisa Florestal Brasileira; Vol. 35 No. 83 (2015): jul./set.; 285-2921983-26051809-3647reponame:Pesquisa Florestal Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/771/436Juizo, Claudio Gumane FranciscoLoiola, Pedro LícioZen, Linéia RobertaMarchesan, RaquelCarvalho, Douglas EdsonBila, Narcísio FernandoEgas, Andrade FernandoRocha, Márcio Pereira daKlitzke, Ricardo Jorgeinfo:eu-repo/semantics/openAccess2017-04-28T12:42:02Zoai:pfb.cnpf.embrapa.br/pfb:article/771Revistahttps://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:2017-04-28T12:42:02Pesquisa Florestal Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
