Resumo: A group of Rhizobium sp. strains isolated from several legume trees from diverse environments was assayed in culture medium at pH 4,6 with and without 50 µM Al3+, using bromocresol green indicator and at pH 6,2 using bromocresol purple indicator. From 211 Rhizobium strains isolated from legume trees, 85.7%, 48.8% and 28.0% from the subfamilies Caesalpinioideae, Mimosoideae and Papilinioideae respectively did grow in culture medium with pH 4.6 and without 50 µM Al3+.One strain did grow without but not with AI3+. Of the 211 strains 77 grow alter increasing the pH of the medium and only 19 were able to grow at pH 4,6 without increasing the pH of the medium. These strains seem the most promising for further tests with plants for acid soils.

De 211 estirpes de Rhizobium testadas, 85,7%, 48,8% e 28,0% isoladas, respectivamente, das subfamílias Caesalpinioideae, Mimosoideae e Papilinioideae cresceram em meio de cultura com pH 4,6 com e sem 50 µM Al3+. Uma estirpe cresceu na ausência, mas não cresceu na presença de Al3+. Os resultados mostraram ainda que das 211 estirpes originalmente testadas, 77 cresceram após aumentar o pH do meio e somente 19 foram capazes de crescer em pH 4,6 sem antes elevar o pH do meio. Para seleção de estirpes para solos ácidos, somente estas deveriam ser testadas na planta, abreviando assim o processo.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraSilva, Gisele Gomes daFranco, Avilio A.2014-04-16info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/17510Pesquisa Agropecuaria Brasileira; v.19, s/n, jun. 1984; 169-173Pesquisa Agropecuária Brasileira; v.19, s/n, jun. 1984; 169-1731678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/17510/11743info:eu-repo/semantics/openAccess2014-04-16T19:15:44Zoai:ojs.seer.sct.embrapa.br:article/17510Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-16T19:15:44Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
