Resumo: Woods of thirteen species occurring in the Amazon region, Pantanal and northeastern Brazil were studied. The total biomass and cellulose and lignine contents per m³ were estimated based on the specific gravity. The estimate cellulose and, lignine per m³ was obtained based on the specific gravity and percentual factor 0.80. Woods with possibility to be utilized for pulp were indicated according to their coeficients of flexibility and rigidity and on the Runkel's index of fibres. Woods indicated for energy production were determined weith base on their specific weight, wall fraction of fibres, percentual factor 0.80, and on their frequency of vessels and fibres.

A biomassa total por m3 de madeira foi determinada com base no peso específico, e a estimativa de celulose e lignina por m³ foi feita com base no peso específico e fator percentual 0,80. A indicação de madeiras para produção de papel foi realizada tomando-se por base os coeficientes de rigidez e flexibilidade e o índice de Runkel. Por outro lado, a qualificação de madeiras destinadas à geração de energia foi feita com base no peso específico, na fração parede das fibras, fator percentual 0,80, frequência de vasos e fibras, e parênquima radial e axial.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraPaula, José Elias deAlves, José Luiz de Hamburgo2014-04-17info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/16555Pesquisa Agropecuaria Brasileira; v.24, n.12, dez. 1989; 1461-1471Pesquisa Agropecuária Brasileira; v.24, n.12, dez. 1989; 1461-14711678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/16555/10831info:eu-repo/semantics/openAccess2014-09-01T17:42:22Zoai:ojs.seer.sct.embrapa.br:article/16555Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-09-01T17:42:22Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
