Resumo: In Brazilian soils the occurrence of manganese toxicity problems is more frequent than deficiency. With this in mind, six soybean cultivars (IAC-Foscarin 31, Davis, BR-4, BR-6, Bragg, IAS-5, IAC-13 and Paraná) were tested in a nutrient solution containing four levels of manganese (0,11; 2; 4 and 6 mg/l) under constant temperature of 25 ± 1°C. Tolerance was measured taking into consideration the dry matter weight of the nerial parts after 15 days in nutrient solution, visual symptoms of toxicity, and the concentration of the Mn in the aerial parts. The results showed that the Davis and IAC-Foscarin 31 cultivars were tolerant, whereas Bragg, IAS-5, BR-4, BR-6 and IAC-13 were intermediate, and the cultivar Paraná very sensitive to high Mn concentrations. The scores given for visual symptoms of toxicity concides negatively with the data of dry matter weight of the plants, and positively with the manganese absorbed. This method was considered to be practical when one deals with great quantity of breeding limes in a soybean breeding program.

Diante disso, avaliaram-se seis cultivares precoces de soja (IAC-Foscarin 31, Davis, BR-4, BR-6, Bragg, IAS-5, IAC-13 e Paraná) em soluções nutritivas contendo quatro níveis de manganês (0,11; 2; 4 e 6 mg/l) a temperatura constante de 25 ± 1°C. A reação de tolerância foi medida após 15 dias de cultivo, levando-se em consideração o peso seco da parte aérea das plantas, os sintomas visuais de toxicidade e as concentrações de manganês na parte aérea. Os resultados mostraram que as cultivares Davis e IAC-Foscarin 31 foram as mais tolerantes, enquanto que as cultivares Bragg, IAS-5, BR-4, BR-6 e IAC-13 foram medianamente tolerantes, e a cultivar Paraná, a mais sensível ao Mn. A avaliação visual através de notas para a sintomatologia dos graus de toxicidade coincidiu negativamente com o peso da matéria seca das plantas, e positivamente com o manganês absorvido. O método utilizado foi considerado prático na separação dos genótipos avaliados em grande quantidade em um programa de melhoramento de sojaPesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraMascarenhas, Hipólito Assunção AntonioMiranda, Manoel Albino Coelho deTanaka, Roberto TetsuoFalivene, Sonia Maria PierroDechen, Antonio Roque2014-04-17info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/13472Pesquisa Agropecuaria Brasileira; v.25, n.4, abr. 1990; 609-615Pesquisa Agropecuária Brasileira; v.25, n.4, abr. 1990; 609-6151678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/13472/7580info:eu-repo/semantics/openAccess2014-04-17T14:30:52Zoai:ojs.seer.sct.embrapa.br:article/13472Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-17T14:30:52Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
