Resumo: Under greenhouse conditions, the effect of sulfentrazone rates (0, 36, 72, 108 and 144 µg m-2 of a.i.) was evaluated on growth of nodules in soybean (Glycine max(L.) Merrill cv. BR-16), inoculated with Bradyrhizobium japonicum strain SEMIA 5079, on dinitrogen fixation estimated by the content of ureides in xylem exsudate. The amino acids, nitrate and ureides contents in xylem exsudate were also determined. The number and dry matter of nodules, the content of amino acids, nitrate and ureides decreased as a function of increase of sulfentrazone rate at R3 and R5 development stages of soybean stages.

Merrill cv. BR-16) infectada com Bradyrhizobium japonicum estirpe SEMIA 5079, e na fixação de dinitrogênio, estimada pelos teores de ureídeos no exsudato do xilema. Foram quantificados, também, os teores de aminoácidos e nitrato no exsudato do xilema. O número e a matéria seca dos nódulos, as concentrações de aminoácidos, nitrato e ureídeos decresceram com o incremento na dose de sulfentrazone, tanto no estádio R3quanto no R5 de desenvolvimento da soja.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraArruda, João SilveiraLopes, Nei FernandesBacarin, Marcos Antonio2001-02-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/6123Pesquisa Agropecuaria Brasileira; v.36, n.2, fev. 2001; 325-330Pesquisa Agropecuária Brasileira; v.36, n.2, fev. 2001; 325-3301678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/6123/3190info:eu-repo/semantics/openAccess2014-11-06T16:49:45Zoai:ojs.seer.sct.embrapa.br:article/6123Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-11-06T16:49:45Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
