Resumo: | Human activities have caused damage to Cerrado, the second largest biome in Brazil. Among the most threatened Cerrado phyto-physiognomies stand out gallery forests. Many projects have aimed at gallery forest restoration, but herb invasion hinders the establishment and development of Cerrado woody species. In this scenario, 2 ha of gallery forest along Cabeça de Veado stream within the Brasília Botanical Garden were cleared for subsistence agriculture and the area was subsequently dominated by Melinis minutiflora Beauv. (molasses grass). Some attempts at site restoration have failed due to competition between M. minutiflora and planted tree seedlings. Thus, this study aimed to evaluate the effect of using geotextile collars made of natural fbers on survival and development of Cerrado tree seedlings introduced in the area dominated by molasses grass. Seedlings of third native tree species were planted in holes chemically fertilized, and half of seedlings received geotextile collars while the other half did not for experimental control purpose. Four surveys were carried out, when survival, seedling height and diameter were measured. Results indicate that the geotextile collars increased seedlings survival in 19.6% and seven out third species achieved greater allometric increment from the use of geotextile collars. Increments of two species were higher in the absence of collars and the increment of half of species was not signifcantly affect by the geotextile protection. |

Entre as formações vegetais mais ameaçadas do bioma Cerrado, destaca-se a Mata de Galeria. Programas de recuperação tentam restaurar essa ftofsionomia, mas ervas invasoras difcultam o estabelecimento e o desenvolvimento de espécies nativas lenhosas. Nesse cenário, cerca de 2 ha da Mata de Galeria do Córrego Cabeça de Veado, na área do Jardim Botânico de Brasília, fora desmatada para a prática de agricultura de subsistência e, posteriormente, a área foi dominada por Melinis minutiflora Beauv. (capim-gordura). Algumas tentativas de restauração do local falharam devido à competição dessa erva com as mudas arbóreas plantadas. Dessa forma, este trabalho visou avaliar o efeito do uso de mantas geotêxteis na sobrevivência e desenvolvimento de mudas de espécies arbóreas plantadas em um trecho de Mata de Galeria infestado por capim-gordura. Na área de estudo foram plantadas mudas arbóreas de trinta espécies nativas do Cerrado. Metade das mudas recebeu manta geotêxtil e a outra metade das mudas não recebeu essa proteção. Quatro levantamentos foram efetuados, quando se mediram a sobrevivência, a altura e o diâmetro das mudas. Os resultados indicaram que as mantas geotêxteis aumentaram em 19,6% a sobrevivência de plantas e que sete das trinta espécies apresentaram maior incremento alométrico com o uso de mantas geotêxte is. Duas espécies se desenvolveram mais sem a presença de mantas geotêxteis e o incremento de metade das espécies não foi signifcativamente afetado pelo uso desse protetor.Universidade Federal de Santa Maria2019-06-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/401610.5902/198050984016Ciência Florestal; Vol. 29 No. 2 (2019); 795-810Ciência Florestal; v. 29 n. 2 (2019); 795-8101980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/4016/pdfCopyright (c) 2019 Ciência Florestalinfo:eu-repo/semantics/openAccessArtioli, Camila GrazielaCorrea, Rodrigo Studart2019-09-05T20:52:46Zoai:ojs.pkp.sfu.ca:article/4016Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2019-09-05T20:52:46Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false |
