Resumo: | We aimed to differentiate the vigor of soybean seeds through antioxidant enzyme activity (superoxide dismutase-SOD, ascorbate peroxidase-APX, and catalase- CAT) and relate them to the viability and vigor standard tests to verify if these enzymes detect tenuous differences in seed vigor. The following tests were performed: germination, fi rst germination count, germination speed index, initial growth of seedlings, electrical conductivity, and respiratory and enzymatic activity. It was only possible to differentiate just two lots of soybean seeds by vigor and germination test, considering that viability had higher germination in lot 2 (91%), which did not differ from lot 3 (87.17%) nor from lot 1 (85.17%), while SOD and APX enzymes activity, in the roots, differed amongst the three lots. Thus, it was concluded that the viability and vigor standard tests relate to antioxidant enzyme activity, characterizing this method as an effi cient tool for detecting small differences in the vigor of soybean seeds. |

Foram realizados os seguintes testes: germinação, primeira contagem e índice de velocidade de germinação, crescimento inicial de plântulas, condutividade elétrica, atividade respiratória e enzimática. Foi possível diferenciar apenas dois lotes de sementes de soja pelos testes de vigor e germinação, sendo que a viabilidade apresentou maior germinação para o lote 2 (91%), não diferindo do lote 3 (87,17%), diferindo do lote 1 (85,17%), enquanto que a atividade das enzimas SOD e APX, nas raízes, diferenciou as sementes em três lotes. Portanto, conclui-se que os testes padrão de viabilidade e vigor têm relação com a atividade das enzimas antioxidantes, caracterizando este método como uma ferramenta efi ciente para detectar pequenas diferenças no vigor de sementes de soja.Iheringia.
