Resumo: Oats (Avena spp.) represent one of the most important crops in the South of Brazil during the winter growing season. In its plants there are allelopathic substances present, which refer the importance of the understanding of this phenomenon in the crop. The aim of this work was to estimate the allelopathic potential of different genotypes based on the analyses of their initial phase as well as on the evaluation of their allelochemicals. Results of this study showed that oat genotypes present allelopathic potential. Genotypes that present greater allelopathic effects during the initial period are UPF 13, UFRGS 9, UFRGS 10, and UFRGS 6. In the same way, those genotypes that exhibit lesser effects are UFRGS 12, UFRGS 17, UFRGS 884077, and UPF 12. The effects caused by the allelochemical scopoletin are similar to those observed by oat genotypes, suggesting a cause and effect relationship.

Sabe-se que nela existem agentes alelopáticos, o que torna conveniente o entendimento deste fenômeno na cultura. Neste trabalho, buscou-se realizar uma estimativa do potencial alelopático com base na análise da fase inicial (estabelecimento) do ciclo de diferentes genótipos de aveia, bem como na avaliação de seus aleloquímicos. A partir da análise dos dados, verifica-se que os genótipos de aveia apresentam potencial alelopático, e que UPF 13, UFRGS 9, UFRGS 10 e UFRGS 6 são os que mostram maior efeito. Por outro lado, UFRGS 12, UFRGS 17, UFRGS 884077 e UPF 12 exibem menor efeito. Os efeitos produzidos pelo aleloquímico escopoletina são semelhantes aos provocados pelos próprios genótipos de aveia, o que mostra semelhança entre o efeito alelopático produzido pela substância e o provocado pelos genótipos.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraJacobi, Ubiratã SoaresFleck, Nilson Gilberto2000-01-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/5680Pesquisa Agropecuaria Brasileira; v.35, n.1, jan. 2000; 11-19Pesquisa Agropecuária Brasileira; v.35, n.1, jan. 2000; 11-191678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/5680/2784info:eu-repo/semantics/openAccess2014-08-15T16:38:49Zoai:ojs.seer.sct.embrapa.br:article/5680Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-08-15T16:38:49Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
