Resumo: There are few studies related to the impact of burnings on soil fungi present in the cerrado. The aim of this work was identify the mycoflora in cerrado soil samples before and afer burning process at two depths; observing the interference of this process in the fungi soil inhabitants population. The samples were collected in area, in the municipality of Jaú do Tocantins, State of Tocantins. Bioassays were installed in a completely randomized experimental design, with four replicates and fve treatments, represented by different concentrations of soil solution. The identifcation of the fungi was made at the genus level according to their morphological structures formed in culture medium through optical microscope observations. In the before burning area we observed greatest diversity of genera and fungi colonies. The opposite was found in the area subsequently submitted to the burning process, showing minor fungal colonies. Among the genera identifed, Aspergillus, Penicillium, Cladosporium, Fusarium, Mucor, Pythium and Trichoderma were the most representative colonies. We observed a reduction of 45% approximately in the population of antagonistic fungi. It was found that the use of fre in vegetation negatively influenced microbial populations present in the surface layers of cerrado soil.

Existem poucos estudos relacionados ao impacto de queimadas sobre os fungos habitantes do solo presente no cerrado. Objetivou-se com este trabalho identifcar a micoflora presente em amostras de solos, antes e após o processo de queimada em duas profundidades, observando a interferência deste processo na população de fungos habitantes do solo. As amostras foram coletadas em uma área, no município de Jaú do Tocantins, Estado do Tocantins. Foram instalados bioensaios em delineamento experimental inteiramente casualizado, com quatro repetições e cinco tratamentos, representados por diferentes concentrações de solução do solo. A identifcação dos fungos foi feita, em nível de gênero, de acordo com suas estruturas morfológicas formadas em meio de cultura, através de observações em microscópio ótico. Na área antes da queimada, observou-se a presença de maior diversidade de gêneros e quantidade de colônias fúngicas. O contrário foi constatado na área posteriormente submetida à queimada, que apresentou menor número de colônias fúngicas. Dos gêneros identifcados, destacaram-se Aspergillus, Penicillium, Cladosporium, Fusarium, Mucor, Pythium e Trichoderma, que apresentaram maior número de colônias em quantidades representativas. Observou-se ainda uma redução em torno de 45% na população de fungos antagonistas. Foi possível constatar que o uso do fogo na vegetação influenciou negativamente as populações microbianas presentes nas camadas mais sup Universidade Federal de Santa Maria2019-06-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/2261410.5902/1980509822614Ciência Florestal; Vol. 29 No. 2 (2019); 965-974Ciência Florestal; v. 29 n. 2 (2019); 965-9741980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/22614/pdfCopyright (c) 2019 Ciência Florestalinfo:eu-repo/semantics/openAccessSousa, Rosângela Ribeiro deLeão, Evelynne UrzêdoVeloso, Ronice AlvesGiongo, MarcosSantos, Gil Rodrigues dos2019-09-05T21:16:27Zoai:ojs.pkp.sfu.ca:article/22614Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2019-09-05T21:16:27Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false
