Resumo: The objective of this work was to determine the root growth capacity of 75 genotypes of small graine cereals in hydroponic culture under different aluminum concentrations, and to assess the relationship betwen the level of tolerance/sensitivity in hydroponic solution and the resistance/susceptibility index in the field. Barley, triticale, rye, wheat and Aegilops tauschii were evaluated in hydroponics, with Al3+ concentrations that varied between 0.5 (barley), 2 and 6 (triticale), 6 and 10 (rye) and 2 mg L-1 (wheat and Ae. tauschii). The experiments' designs were completely randomized. In the field trial, the same genotypes were assessed, except for Ae. tauschii, in soil with pH 4.4 and 4.85 adjusted to 1/2 and 1/4 of the SMP index. A score scale ranging from 0.5 (highly resistant) to 5 (highly susceptible) was used. A strong relationship between aluminum tolerance in hydroponics and resistance to blight in the field was observed. Cereals selection in hydroponic medium can be considered an efficient tool to support breeding programs for this characteristic.

Os cereais cevada, triticale, centeio, trigo e Aegilops tauschii foram avaliados em hidroponia, com concentrações de Al3+ que variaram entre 0,5 (cevada), 2 e 6 (triticale), 6 e 10 (centeio) e 2 mg L-1 (trigo e Ae. tauschii). Os delineamentos experimentais foram inteiramente casualizados. Em campo, foram avaliados os mesmos genótipos, exceto Ae. tauschii, em solo com pH 4,4 e 4,85, corrigido a 1/2 e 1/4 do índice SMP. Utilizou-se uma escala de notas com variação de escores de 0,5 (altamente resistente) a 5 (altamente suscetível). Foi observada elevada relação entre a tolerância ao alumínio em hidroponia e a resistência ao crestamento em campo. A seleção de cereais em meio hidropônico pode ser considerada eficiente como ferramenta de apoio aos programas de melhoramento genético para essa característica.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraTrabalho desenvolvido com apoio financeiro do CGIAR/Generation Challenge Programme e Embrapa Trigo.Portaluppi, RobertoBrammer, Sandra PatussiMagalhães, Jurandir Vieira deCosta, Cibele Tesser deCaierão, EduardoJunior, Alfredo do Nascimentoda Silva Junior, José Pereira2011-01-10info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/5092Pesquisa Agropecuaria Brasileira; v.45, n.2, fev. 2010; 178-185Pesquisa Agropecuária Brasileira; v.45, n.2, fev. 2010; 178-1851678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/5092/6004info:eu-repo/semantics/openAccess2014-10-16T19:11:41Zoai:ojs.seer.sct.embrapa.br:article/5092Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-10-16T19:11:41Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
