Resumo: Four greenhouse experiments were conducted to study the possibility of using 32P, in aluminum tolerance tests of bean (Phaseolus vulgaris L.) The cultivars were previously classified according to dry matter yield date by regression analysis as aluminum tolerant (C20 - Mulatinho Paulista; C26 - Ricobaio 1014; and C33 - Roxo 750) and aluminum sensitive (C17, - Jamapa; C28 - Rio Tibagi; and C34. Tambó). Chopped roots from plant grown in a complete nutrient solution during thirty days and submerged in another solution containing aluminum showed to be a reliable indicator of 32P absorption efficiency to aluminum tolerant and sensitive cultivars. Rate of 32P uptake was more in aluminum tolerant cultivars than sensitive ones. These results are showing that aluminum tolerant cultivars can absorb phophorus more efficiently than sensitive ones. External ionic concentration (NaH2PO4) increased 32P absorption in presence of 48 ppm of aluminum.

As cultivares foram classificadas previamente, de acordo com os dados de produção de matéria seca, através de análises de regressão como tolerantes (C20 - Mulatinho Paulista, C26 - Ricobaio 1014 e C33 – Roxo 750) e sensíveis ao alumínio (C13 - Jamapa, C28 - Rio Tibagi e C34 - Tambó). Raízes provenientes de plantas cultivadas em soluções nutritivas completas durante trinta dias e submersas em outra solução contendo alumínio mostrou ser um indicador confiável da eficiência de absorção de 32P das cultivares tolerantes e sensíveis ao alumínio. A taxa de absorção de 32P foi maior nas cultivares tolerantes que nas sensíveis. Esses resultados mostram que as cultivares tolerantes ao alumínio podem absorver fósforo com maior eficiência que as sensíveis. A concentração iônica externa (NaH2PO4) aumentou a absorção de 32P na presença de 48 ppm de alumínio.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraOliveira, Itamar Pereira deMalavolta, Eurípedes2014-04-16info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/15161Pesquisa Agropecuaria Brasileira; v.18, n.2, fev. 1983; 91-104Pesquisa Agropecuária Brasileira; v.18, n.2, fev. 1983; 91-1041678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/15161/8952info:eu-repo/semantics/openAccess2014-04-16T18:50:35Zoai:ojs.seer.sct.embrapa.br:article/15161Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-16T18:50:35Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
