Resumo: | The objective of this work was to evaluate the burning and cultivation effects on soil seedbanks originally under cerrado vegetation. Two areas under cerrado sensu stricto were sampled, one burned and the other one not burned, as well as areas under tilled crop and pasture. There was no reduction on seedbank, although lower number of species and families and diversity index (Shannon and Simpson) with burning were observed. There was also greater importance value index (IVI) and number of native species, in the non burned area, and of weeds in the burned one. It was observed that the crop area had higher seed density than the pasture and cerrado areas. The species with the highest IVI in the areas were those considered as weeds and forages. The crop area presented lower IVI of native species than the pasture and cerrado areas; besides, it presented diversity indexes (Shannon and Simpson) and native species percentage lower than pasture and cerrado. The cultivation with crop cause higher disturbance in the areas than burning. |

Foi realizada amostragem em área sob cerrado sensu stricto queimada e não queimada, assim como em área de pastagem e lavoura com preparo convencional do solo. Não houve redução no banco de sementes, embora tenha havido menor número de espécies e de famílias, e dos índices de diversidade, com a queimada. Houve maior índice de valor de importância (IVI) e número de espécies nativas, na área não queimada, e de espécies invasoras na área queimada. Na área de lavoura, houve maior densidade de sementes do que na área de pastagem e de cerrado. As espécies com o maior IVI nas áreas foram aquelas consideradas invasoras e forrageiras. A área de lavoura apresentou menores IVI de espécies nativas, índices de diversidade (Shannon e Simpson) e percentagem de espécies nativas do que as áreas de pastagem e cerrado. O cultivo com lavoura causa maior perturbação nas áreas do que a queimada.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraInstitut de recherche pour le développement (IRD), Ministère de affaires étrangères (MAE) e Embrapa CerradosIkeda, Fernanda SatieMitja, DanielleVilela, LourivalSilva, José Carlos Sousa2008-10-23info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/305Pesquisa Agropecuaria Brasileira; v.43, n.6, jun. 2008; 667-673Pesquisa Agropecuária Brasileira; v.43, n.6, jun. 2008; 667-6731678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/305/5438info:eu-repo/semantics/openAccess2014-07-02T17:37:33Zoai:ojs.seer.sct.embrapa.br:article/305Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-07-02T17:37:33Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
