Resumo: Four greenhouse experiments were carried out to study host plant specificity in beans (Phaseolus vulgaris L.) and the interference of several nutrients. In these experiments, four commercial bean varieties and several more or less efficient Rhizobium strains were used. The results of the experiments showed that the efficiency of the symbiosis was dependent on both, strains and varieties. Molybdenum was essential for optimal nitrogen fixation. However excess, molybdenum was more detrimental to nitrogen fixation and nodulation than to plant growth. Potash and magnesium seemed to reduce nodulation and nitrogen fixation whereas calcium had a stimulating effect. These elements interferred equally in both varieties. Nitrogenous fertilizer however had inhibiting effects on nodulation which varied with the varieties.

Com os dados obtidos pudemos concluir que de fato existe um comportamento diferente na fixação de N das estirpes quando em simbiose com diferentes variedades. O molibdênio, que se mostrou indispensável na fixação do N, quando em excesso prejudicou mais o processo da simbiose do que o desenvolvimento das plantas. O K e o Mg foram prejudiciais para a simbiose e fixação do N, enquanto o Ca foi indispensável para um perfeito processamento da simbiose. Não houve diferença entre as variedades em relação à nutrição com estes elementos. O adubo nitrogenado entretanto agiu diferentemente na simbiose das variedades, inibindo a nodulação da variedade Rico 23 e não das outras.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraFranco, Avílio A.Döbereiner, Johanna2014-04-15info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/17963Pesquisa Agropecuaria Brasileira; v.2, n.1, jan. 1967; 467-474Pesquisa Agropecuária Brasileira; v.2, n.1, jan. 1967; 467-4741678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/17963/12411info:eu-repo/semantics/openAccess2014-04-15T18:12:14Zoai:ojs.seer.sct.embrapa.br:article/17963Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-15T18:12:14Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
