Resumo: The forest fres spread mainly through the surface of combustible material. Therefore, low flammability plants can be used for the protection against forest fres because these plants hinder the spread of fre. In this regard, the objective was to make a poll to fnd low flammability plants occurred in cerrado (savanna) of Distrito Federal in burned areas, and, after collecting samples, catalog their characteristics. It was done by plotting and photographing specimens of preserved adjacent vegetation consumed by the flames. Then, samples of high and low flammability leaves were collected to number their particular physical and foliar properties and make an immediate analysis. The samples classifed as low flammability plants were: Vochysia thyrsoidea, Palicourea rigida, Lavoisiera bergii. The sample of the grass Echinolaena inflexa, was considered of high flammability. Comparing the Echinolaena inflexa, Vochysia thyrsoidea, Palicourea rigida and Lavoisiera bergii, they presented good indexes that enable them to be of low flammability species, especially the Palicourea rigida which presented high moisture content (173%), higher foliar thickness (5.6 mm), volatile contents of 76% and combustion heat in the feld moisture of 1263 cal/g. The results confrmed the low flammability of Vochysia thyrsoidea, Palicourea rigida and Lavoisiera bergii being these indicated for the use in green frebreaks.

Portanto, plantas de baixa inflamabilidade podem ser usadas para proteção contra incêndios florestais, pois dificultam a propagação do fogo. Neste sentido, o objetivo deste trabalho foi realizar um levantamento de plantas de baixa inflamabilidade no cerrado do Distrito Federal e, a partir de amostras coletadas, caracterizá-las. O levantamento dessas plantas deu-se por meio do caminhamento em áreas queimadas, fotografando espécimes relativamente preservados adjacentes a vegetação consumida pelas chamas. Depois, foram coletadas amostras de folhas das espécies de baixa e de alta inflamabilidade para caracterização das propriedades físicas, foliares e análise imediata. As espécies classificadas como de baixa inflamabilidade foram Vochysia thyrsoidea, Palicourea rigida e Lavoisiera bergii. Já a gramínea Echinolaena inflexa é considerada de alta inflamabilidade. As análises mostraram que, em comparação com E. inflexa, as espécies V. thyrsoidea, P. rigida e L. bergii apresentaram bons índices que as habilitam como espécies de baixa inflamabilidade. Entre elas, P. rigida destaca-se ao apresentar elevado teor de umidade (173%), maior espessura (5,6mm), teor de voláteis de 76% e calor de combustão na umidade de campo de 1.263 cal/g. Os resultados confirmaram a baixa inflamabilidade de V. thyrsoidea, P. rigida, e L. bergii sendo estas indicadas para uso em aceiros verdes.Universidade Federal de Santa Maria2019-04-04info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/2241610.5902/1980509822416Ciência Florestal; Vol. 29 No. 1 (2019); 181-192Ciência Florestal; v. 29 n. 1 (2019); 181-1921980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/22416/pdfCopyright (c) 2019 Ciência Florestalinfo:eu-repo/semantics/openAccessSouza, Michel AquinoVale, Ailton Teixeira2020-06-05T19:47:20Zoai:ojs.pkp.sfu.ca:article/22416Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2020-06-05T19:47:20Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false
