Resumo: | A work was carried out with the purpose of evaluating the physiological quality of osmoconditioned soybean (Glycine max (L.) Merrill) seeds of UFV-10, IAC-8 and Doko RC varieties, in terms of response to stress induced by the accelerated aging test. Seeds were osmoconditioned in PEG 6000, with an osmotic potential of -0.8 MPa and 20oC of temperature, for four days. After that, seeds were dried back to the initial moisture content and submitted to the accelerated aging test for the following periods: 0, 24, 48 and 72 hours. Two controls were used: untreated seeds and seeds soaked in water. After several determined accelerated aging periods, seeds were evaluated by the standard germination test, seedling length and dry biomass of seedlings. In greenhouse the speed of emergence-index and the final emergence in sand seedbed were determined. Soybean seeds hydration-dehydration treatment in PEG 6000 solution improved seed performance in relation to germination and vigor. The extent of the accelerated aging period affected seed performance in all parameters evaluated. However, PEG 6000 treatment was satisfactory in maintaining the seed quality during the accelerated aging periods. The soybean seed water soaking affected negatively the physiological seed quality. The soybean varieties showed differential response to the hydration-dehydration treatments and to the accelerated aging periods. |

Foi conduzido um experimento com o objetivo de avaliar a qualidade fisiológica de sementes de soja (Glycine max (L.) Merrill) , envolvendo as variedades UFV-10, IAC-8 e Doko RC, submetidas ao processo de hidratação-desidratação, seguido por uma condição de estresse induzida pelo teste de envelhecimento acelerado. As sementes foram pré-condicionadas em PEG 6000, com potencial osmótico de -0,8 MPa, a uma temperatura de 20oC, por quatro dias. Em seguida, as sementes foram novamente desidratadas, até atingir o conteúdo de umidade inicial, sendo então submetidas ao teste de envelhecimento acelerado pelos seguintes períodos: 0, 24, 48 e 72 horas. As sementes pré-condicionadas foram comparadas com duas testemunhas: sementes não-tratadas e sementes embebidas em água. Após cada período de envelhecimento, as sementes foram avaliadas pelo teste padrão de germinação, comprimento de plântula e biomassa seca das plântulas. Em casa de vegetação, determinaram-se o índice de velocidade de emergência e a emergência final em substrato de areia. O tratamento de hidratação-desidratação em solução de PEG 6000 melhorou o desempenho das sementes em termos de germinação e vigor. O aumento nos períodos de envelhecimento acelerado influenciou negativamente o desempenho das sementes, em todos os tratamentos avaliados. Contudo, o tratamento com PEG 6000 foi satisfatório em manter a qualidade das sementes. A embebição das sementes de soja em água desmineralizada prejudicou a qualidade fisiológica. As variedades de soja mostraram resposta diferenciada aos tratamentos de hidratação-desidratação e aos períodos de envelhecimento acelerado.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraBraccini, Alexandro de Lucca eReis, Múcio SilvaSediyama, Carlos SigueyukiScapim, Carlos AlbertoBraccini, Maria do Carmo Lana1999-06-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/5294Pesquisa Agropecuaria Brasileira; v.34, n.6, jun. 1999; 1053-1066Pesquisa Agropecuária Brasileira; v.34, n.6, jun. 1999; 1053-10661678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/5294/2486info:eu-repo/semantics/openAccess2010-07-13T12:37:47Zoai:ojs.seer.sct.embrapa.br:article/5294Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2010-07-13T12:37:47Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
