Resumo: | This work aimed to evaluate the natural durability of heartwood and sapwood of Luhea divaricata, Carya illinoinensis and Platanus x acerifolia. Test samples measuring 2.5 x 2.5 x 30.0 cm (radial x tangential x longitudinal) were placed in a pine forest stand and an open field. During a year, the samples were repeatedly weighed and evaluated by a rating system to determine mass loss and decay index, respectively. The results showed that regardless of species and type of wood, the forest environment is more favourable to decay than that of the open field. Despite the high correlation between mass loss and decay index, variations in the durability of wood were found between these parameters. The wood from the internal section of the log (sapwood) was the more affected. For mass loss, no significant variation was observed for the species analyzed, however, for the decay index Platanus x acerifolia was shown to be the most affected. |

Durante um ano, as amostras foram periodicamente pesadas e avaliadas pelo critério de notas, para determinar o percentual de perda de massa e índice de deterioração, respectivamente. Os resultados mostraram que, independente da espécie e do tipo de lenho, o ambiente dentro da floresta é mais favorável a deterioração da madeira do que fora dele. Apesar da elevada correlações entre a perda de massa e o índice de deterioração foram observadas variações na avaliação da durabilidade da madeira entre esses critérios. Para todas as espécies, a madeira proveniente do alburno foi a mais atacada. Para perda de massa não foi observada diferença entre as espécies avaliadas, entretanto, o índice de deterioração apontou o plátano como a mais atacada.Universidade Federal de Santa Maria2010-06-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/185810.5902/198050981858Ciência Florestal; Vol. 20 No. 2 (2010); 357-365Ciência Florestal; v. 20 n. 2 (2010); 357-3651980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/1858/1203Melo, Rafael Rodolfo deStangerlin, Diego MartinsSantini, Elio JoséHaselein, Clovis RobertoGatto, Darci AlbertoSusin, Felipeinfo:eu-repo/semantics/openAccess2017-05-05T14:25:25Zoai:ojs.pkp.sfu.ca:article/1858Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2017-05-05T14:25:25Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false |
