Resumo: | The purpose of this study was to evaluate the quality of Eucalyptus benthamii wood for kraft pulp production. A hybrid of Eucalyptus urophylla x Eucalyptus grandis, probably the most planted Eucalyptus clone in Brazil, was also analyzed for comparison purposes. Basic density, chemical composition and fiber dimensions were determined for the two species. The Eucalyptus benthamii wood presented an anatomical structure, basic density and fiber dimensions quite similar to those of other species planted by the Brazilian pulp industry. However, it presented poorer wood quality characteristics when compared to the hybrid urograndis species, with higher amounts of extractives and lignin, lower amount of glucans, more galactans and lower S/G ratio, characteristics leading to lower pulping yield. Additional studies should be carried out to establish its pulping, bleaching and paper strength properties. |

Suas características foram comparadas com as de um híbrido de Eucalyptus grandis x Eucalyptus urophylla que é, provavelmente, o clone mais plantado no Brasil e, portanto, de grande importância no setor nacional de celulose e papel. Determinaram-se a densidade básica, composição química e características dimensionais das fibras das duas espécies. A madeira do Eucalyptus benthamii apresentou estrutura anatômica bastante semelhante às outras espécies do gênero e, ainda, densidade básica e dimensões das fibras dentro dos parâmetros dos clones de Eucalyptus utilizados atualmente pela indústria nacional de celulose e papel. Do ponto de vista de constituição química, o Eucalyptus benthamii demonstrou possuir qualidade tecnológica inferior à do híbrido urograndis, pois apresentou maiores teores de extrativos e de lignina, menor teor de glucanas, maior teor de galactanas e menor relação S/G (Siringila/Guaiacila), características que contribuem para um menor rendimento em polpa. Estudos deverão ser realizados para avaliar o desempenho da espécie na polpação kraft, no branqueamento e as propriedades de resistências da polpa celulósica.Universidade Federal de Santa Maria2011-03-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/275910.5902/198050982759Ciência Florestal; Vol. 21 No. 1 (2011); 167-174Ciência Florestal; v. 21 n. 1 (2011); 167-1741980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/2759/1685Alves, Isabel Cristina NogueiraGomide, José LívioColodette, Jorge LuizSilva, Helton Damin dainfo:eu-repo/semantics/openAccess2017-05-04T17:11:22Zoai:ojs.pkp.sfu.ca:article/2759Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2017-05-04T17:11:22Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false |
