Resumo: | The present work aimed to evaluate some technological characteristics of the wood of two commercial hybrid clones of Eucalyptus spp and two hybrid clones of Corymbia spp, implanted in three different planting spacings, at 24 months of age. Four trees per clone were sampled at each spacing to determine the following wood characteristics: basic density, gross calorific value, energy density and cellulose, hemicellulose, lignin, ash and carbon contents. There was a significant effect of the clone x spacing interaction for the basic density, energy density, lignin and cellulose contents of the wood. Eucalyptus showed the highest levels of lignin and cellulose, and hybrid clones of Corymbia the highest values of basic density and energy density of wood, with emphasis on clone C3, where the highest averages of the study were verified. For the levels of hemicelluloses and ash in the wood, the clone effect and spacing effect were observed. As for the carbon content and the gross calorific value in the wood, there was no significant effect, either from the clone, the spacing or the interaction of these two factors. The results show that there is variability in the characteristics between the genetic materials evaluated and in relation to the planting spacing tested. It should be noted that the choice of the best genetic material should be based on the technological characteristics of the wood, but also the forest productivity associated with good silviculture of the species should be evaluated. |

Quatro árvores por clone foram amostradas em cada espaçamento para determinar as seguintes características da madeira: densidade básica, poder calorífico superior, densidade energética e teores de celulose, hemiceluloses, lignina, cinzas e carbono. Observou-se efeito significativo da interação clone x espaçamento para a densidade básica, densidade energética, teores de lignina e de celulose da madeira. Os clones de Eucalyptus apresentaram os maiores teores de lignina e celulose, e coube aos clones híbridos de Corymbia os maiores valores de densidade básica e da densidade energética da madeira, com destaque para o clone C3, onde se verificou as maiores médias do estudo. Para os teores de hemiceluloses e cinzas na madeira, observou-se o efeito de clone e efeito de espaçamento. Quanto ao teor de carbono e ao poder calorífico superior na madeira, não houve efeito significativo, seja do clone, do espaçamento ou da interação desses dois fatores. Os resultados demonstram que há variabilidade das características entre os materiais genéticos avaliados e em relação aos espaçamentos de plantio testados. Cabe ressaltar que a escolha do melhor material genético deve ser baseada nas características tecnológicas da madeira, mas também deve ser avaliada a produtividade florestal associada à boa silvicultura da espécie.Universidade Federal de Santa Maria2023-06-07info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/6496510.5902/1980509864965Ciência Florestal; Vol. 33 No. 2 (2023): Publicação Contínua; e64965Ciência Florestal; v. 33 n. 2 (2023): Publicação Contínua; e649651980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMenghttps://periodicos.ufsm.br/cienciaflorestal/article/view/64965/60971Copyright (c) 2023 Ciência Florestalhttp://creativecommons.org/licenses/by-nc/4.0info:eu-repo/semantics/openAccessLopes, Emerson DelanoGonçalves, Janaína FernandesMarques, AriadneMartins, Nivaldo de SouzaPena, ClaudileneLaia, Marcelo Luiz de2023-06-22T01:14:07Zoai:ojs.pkp.sfu.ca:article/64965Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2023-06-22T01:14:07Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false |
