Resumo: The purposes of this study were to: evaluate de natural durability of three species of tauari (Couratari guianensis Aublet, Couratari oblongifolia Ducke & R.Knuth and Couratari stellata A.C.Smith), report the colorimetric parameters according to CIE L*a*b* 1976 system and also show the appearance of control and attacked wood blocks. Two brown-rot [Gloeophyllum trabeum (Persoon ex Fries) Murril. and Lentinus lepideus Fr.] and two white-rot [Trametes versicolor (Linnaeus ex Fries) Pilat and Ganoderma applanatum (Pers. ex Wallr.)] fungi were used. Tauari wood was classed as “moderately resistant” to “resistant” when exposed to Gloeophyllum trabeum, Trametes versicolor and Ganoderma applanatum fungi. All extractives’ contents of attacked samples decreased when compared with the control (sound wood), except Couratari stellata exposed to Ganoderma applanatum. Conversely, all ash contents increased when compared with the control, except Couratari stellata exposed to Gloeophyllum trabeum. All attacked wood blocks and wood meal samples were darker, except wood meal from Couratari stellata exposed to Trametes versicolor, and redder than the control. The DE* mean value in attacked wood blocks and wood meal samples attained 29.5 and 14.3, respectively.

Dois fungos de podridão-parda [Gloeophyllum trabeum (Persoon ex Fries) Murril. e Lentinus lepideus Fr.] e dois de podridão-branca [Trametes versicolor (Linnaeus ex Fries) Pilat e Ganoderma applanatum (Pers. ex Wallr.)] foram utilizados. A madeira de tauari foi classificada como "moderadamente resistente" a "resistente" quando exposta aos fungos Gloeophyllum trabeum, Trametes versicolor e Ganoderma applanatum. O conteúdo de extrativos das amostras atacadas diminuiu quando comparado com o controle, exceto Couratari stellata expostos a Ganoderma applanatum. Por outro lado, os conteúdos de cinzas aumentaram quando comparados com o controle, exceto para a madeira de Couratari stellata exposto ao Gloeophyllum trabeum. Todos os blocos de madeira atacados e as serragens tornaram-se mais escuras, exceto para a serragem de Couratari stellata exposto ao fungo Trametes versicolor, e mais vermelho do que a amostra sem ataque. O ΔE * médio do bloco de madeira e serragem, atacados, atingiram 29,5 e 14,3, respectivamente. Universidade Federal de Santa Maria2015-09-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/1960910.5902/1980509819609Ciência Florestal; Vol. 25 No. 3 (2015); 581-593Ciência Florestal; v. 25 n. 3 (2015); 581-5931980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/19609/11604Okino, Esmeralda Yoshico ArakakiPastore, Tereza Cristina MonteiroCamargos, José Arlete AlvesCoradin, Vera Terezinha RauberTeixeira, Divino EternoSantana, Marcos Antonio EduardoFagg, Christopher Williaminfo:eu-repo/semantics/openAccess2017-04-10T17:26:07Zoai:ojs.pkp.sfu.ca:article/19609Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2017-04-10T17:26:07Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false
