Resumo: | This work’s main objective was to follow the air-drying of Eucalyptus grandis lumber, carried out in Lavras, MG, and to identify the mycobiota associated with the lumber at various phases of drying. The lumbers were obtained from eight 3.0 meter long logs from 27 year-old trees, planted in an experimental area of UFLA. Results showed that the air-drying of Eucalyptus grandis, started in January, demanded 158 days to achieve moisture content around 12.5 %. The moisture content-time curve was represented by a logarithmic equation with coefficient of determination equal to 98.3 %. The highest occurrence of fungi that cause surface mold and stain was observed at the beginning of the drying. The highest frequencies of fungi were verified at the beginning of the drying for Penicillium spp and Pestalotiopsis sp. The fungus Lentinus lepideus occurred with higher frequency at the end of the drying. |

As tábuas foram cortadas de oito toras de 3,0 m de comprimento, oriundas de três árvores, com 27 anos de idade, plantadas em área experimental da UFLA. Dos resultados, pôde-se concluir que a secagem da madeira de Eucalyptus grandis ao ar livre, iniciada em janeiro, consumiu 158 dias até atingir umidade próxima a 12,5%. A curva de secagem foi representada por uma equação logarítmica com coeficiente de determinação (R2) igual a 98,3%. Os fungos causadores de bolores superficiais e de manchas tiveram maior ocorrência no início da secagem. As mais altas freqüências de fungos, verificadas no início da secagem, foram observadas para Penicillium spp. e Pestalotiopsis sp. O fungo Lentinus lepideus ocorreu com maior freqüência no final da secagem.Universidade Federal de Santa Maria2006-03-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/188610.5902/198050981886Ciência Florestal; Vol. 16 No. 1 (2006); 45-50Ciência Florestal; v. 16 n. 1 (2006); 45-501980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/1886/1132Mesquita, João BasílioLima, José TarcísioTrugilho, Paulo Fernandoinfo:eu-repo/semantics/openAccess2017-05-15T17:21:26Zoai:ojs.pkp.sfu.ca:article/1886Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2017-05-15T17:21:26Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false |
