Resumo: | In this study a survey of weeds occurring in rice (Oryza sativa L.) crops was made in Zona da Mata, MC, Brasil. The floristic composition and the structure of the weed flora were evaluated. During the first months of 1981 some representative rice fields were evaluated in counties with the highést yields in that Zona. Weeds were sampled in crops grown in humid lowland soils and then stored in the Herbário ESAL, of Escola Superior de Agricultura at Lavras, MG, BrasiL Weeds were identified and their rates of occurrence determined. Thirty-three species, from eleven botanic families were found, including eight dicotyledoneous and three monocotyledoneous. The most frequent families were Gramineae, Cyperaceae and Leguminosae and the species Fimbristylis miliacea, Ischaemum rugosum Humenachne sp, Eriochloa polystachia and Ludwigia suffruticosa. Most of the species found in this study have not been cited previously as weeds on rice crops in the State of Minas Gerais |

Percorreram-se nos primeiros meses de 1981 os municípios de maior produção de arroz daquela região, onde a cultura se desenvolve em baixadas e várzeas úmidas, tomando-se como amostras lavouras representativas, indicadas pelos técnicos da EMATER/MG. Coletou- se e anotou-se o grau de abundância das espécies invasoras, as quais, posteriormente, foram identificadas, e, na sua maioria, depositadas no Herbário ESAL, da Escola Superior de Agricultura de Lavras. Constatou-se a presença de 33 espécies, pertencentes a onze famílias botânicas, sendo oito de dicotiledôneas e três de monocotiledôneas. Destacaram-se as famílias Gramineae, Cyperaceae e Leguminosae, e as espécies Fimbristylis miliacea, lschaemum rugosum, Hymenachne sp, Eriochloa polystachia e Ludwigia suffruticosa. A maioria das espécies identificadas não consta da lista de invasoras da cultura do arroz, citadas para o estado de Minas Gerais.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraCarvalho, Douglas Antônio deAlcântara, Elifas Nunes de2014-04-17info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/13329Pesquisa Agropecuaria Brasileira; v.25, n.1, jan. 1990; 25-28Pesquisa Agropecuária Brasileira; v.25, n.1, jan. 1990; 25-281678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/13329/7510info:eu-repo/semantics/openAccess2014-04-17T14:24:18Zoai:ojs.seer.sct.embrapa.br:article/13329Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-17T14:24:18Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
