Resumo: Four rice cultivars (EEA 304, SUVALE 1, IRGA 408 and CICA 4) were screened in nutrient solution for Al tolerance at 0, 10, 20, 40 and 60 ppm Al concentrations. Al injury was characterized by visual toxicity symptoms, decrease in dry weight of tops and roots, length of roots and plant height. A differential tolerance to Al was found among cultivars. EEA 304 was found to be the most tolerant to Al. The others were found to be susceptible to Al in this order: SUVALE 1 < IRGA 408 < CICA 4.

The others were found to be susceptible to Al in this order: SUVALE 1 < IRGA 408 < CICA 4.Quatro cultivares de arroz (EEA 304, SUVALE 1, IRGA 408 e CICA 4) foram selecionadas em solução nutritiva para tolerância a alumínio, em concentrações de 0, 10, 20, 40 e 60 ppm de Al. Os sintomas de toxidez foram caracterizados visualmente, pela produção de matéria seca da parte aérea e raízes, altura da planta e comprimento da raiz. Foi observada uma tolerância diferencial ao Al entre as cultivares. A cultivar EEA 304 foi tolerante ao alumínio, enquanto as outras apresentaram a seguinte ordem decrescente de susceptibilidade: SUVALE 1 < IRGA 408 < CICA 4.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraFageria, Nand Kumar2014-04-15info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/15506Pesquisa Agropecuaria Brasileira; v.17, n.1, jan. 1982; 1-9Pesquisa Agropecuária Brasileira; v.17, n.1, jan. 1982; 1-91678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/15506/9466info:eu-repo/semantics/openAccess2014-04-15T19:45:17Zoai:ojs.seer.sct.embrapa.br:article/15506Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-15T19:45:17Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
