Zusammenfassung:The use of computational resources to assess the physiological potential of seeds has attracted the attention of researchers and professionals in the seed sector. The aim of this study was to evaluate the vigor of cowpea seeds using the Vigor-S software (Automated Seed Vigor Analysis System), in comparison to the information provided by traditional vigor tests that are recommended for the species. Seven seed lots of the cultivar BRS Guariba were used. They underwent germination and seed vigor assessment by testing first germination count, accelerated aging, electrical conductivity, seedling emergence, speed of seedling emergence and use of Vigor-S, an automated image system for seedling assessment, in two evaluation periods. The data underwent analysis of variance, in a completely randomized design and their means were compared by the Scott-Knott test (p ≤ 0.05). An analysis was made of the correlation between the vigor tests traditionally used and the variables provided by Vigor-S. Using the Vigor-S software for automated image analysis of cowpea seedlings three days after sowing is an efficient alternative to detect differences in vigor between seed lots, similarly to traditional seed vigor evaluations. Resumo: O uso de recursos computacionais para a avaliação do potencial fisiológico de sementes tem atraído atenção de pesquisadores e profissionais do setor sementeiro. O objetivo deste estudo foi a avaliação do vigor de sementes de feijão-caupi com a utilização do software Vigor-S (Sistema de Análise Automatizada do Vigor de Sementes). Foram utilizados sete lotes de sementes do cultivar BRS Guariba que foram submetidos aos testes de primeira contagem de germinação, envelhecimento acelerado, condutividade elétrica, emergência de plântulas, velocidade de emergência de plântulas e sistema computadorizado de imagens de plântulas (Vigor-S), avaliados em duas épocas. Os dados foram submetidos a análise da variância, em delineamento inteiramente casualizado e suas médias comparadas pelo teste de Scott-Knott (p ≤ 0,05) e a análise de correlação entre os testes de vigor tradicionalmente utilizados e as variáveis fornecidas pelo Vigor-S. A análise computadorizada de imagens de plântulas de feijão-caupi com três dias após a semeadura por meio do software Vigor-S é uma alternativa eficiente para detectar diferenças de vigor entre os lotes de sementes, de forma similar às avaliações tradicionais do vigor de sementes.
