Resumo: The effects of plant cultivars and strain of Rhizobium on ureide transport in soybean and mineral nitrogen on ureide production and transport in soybean (Glycine max (L.) Merrill), common bean (Phaseolus vulgaris L.) and leucena (Leucaena leucocephala Lam.) were studied. No significant differences were found in the percentage of ureides in xylem sap of field grown soybean cv. PI 240-663 which was inoculated with various Rhizobium strains. Significant differences were however observed between different plant cultivars. Cultivar IAC-5 had the greatest proportion of sap nitrogen as ureides. In the glasshouse, a significant decrease was found in the ureide percentage in the xylem sap of soybean and common bean supplied with nitrate-nitrogen. Applying ammonium-nitrogen 24 hours before harvesting decreased ureide production only when nitrogenase activity was significantly inhibited. Changes in ureide concentration in root and leaf extracts reflected the changes in nodulation and ureide production of nodulated soybean and common bean but not in leucaena.

Merrill), feijão (Phaseolus vulgaris L.) e leucena (Leucaena leucocephala Lam.). Não houve diferenças significativas no teor de ureídos na seiva xilemática da cultivar de soja PI 240-663 crescida no campo e inoculada com diferentes estirpes de Rhizobium. Foram observadas, porém, diferenças significativas entre as cinco cultivares, apresentando a cultivar IAC-5 maior percentagem do N total da seiva sob a forma de ureídos. Em casa de vegetação, foi observada uma diminuição considerável na percentagem do nitrogênio sob a forma de ureídos na seiva de soja e feijão que receberam nitrogênio na forma nítrica. A aplicação de nitrogênio amoniacal 24 horas antes da colheita só diminuiu a produção de ureídos quando a inibição da atividade da nitrogenase foi mais pronunciada. As variações no teor de ureídos nos tecidos de raiz e caule refletiram as variações na produção de ureídos pelos nódulos de soja e feijão, o mesmo não acontecendo com a leucena. Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraGoi, Silvia ReginaNeves, Maria Cristina Prata2014-04-17info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/14265Pesquisa Agropecuaria Brasileira; v.22, n.2, fev. 1987; 163-170Pesquisa Agropecuária Brasileira; v.22, n.2, fev. 1987; 163-1701678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/14265/8185info:eu-repo/semantics/openAccess2014-09-26T17:54:00Zoai:ojs.seer.sct.embrapa.br:article/14265Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-09-26T17:54Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
