O presente trabalho teve como objetivo estudar o comportamento de sementes de feijão submetidas a diferentes metodologias do teste de frio, comparativamente a outros testes de vigor tradicionalmente utilizados na avaliação da qualidade fisiológica dessas sementes. As metodologias do teste de frio utilizadas foram: caixa plástica com terra, rolo de papel com terra e rolo de papel sem terra, nas temperaturas de 10ºC e de 15ºC e períodos de exposição, de três, cinco e sete dias. Paralelamente foram conduzidos teste padrão de germinação, primeira contagem de germinação, envelhecimento acelerado, condutividade elétrica e emergência de plântulas em campo. As diferentes metodologias do teste de frio foram comparadas pelo teste de Tukey e, posteriormente, foram estabelecidas correlações com os demais testes de vigor. A análise dos dados e a interpretação dos resultados permitiram concluir que a metodologia do rolo de papel sem terra, nos períodos de três e cinco dias à 10ºC e à 15ºC, proporcionou melhor correlação com a primeira contagem de germinação e emergência de plântulas em campo. To assess the efficiency of cold test for bean seed vigor determination, two cultivars were evaluated by three different methodologies under two temperatures (10ºC and 15ºC) and three cold period (3, 5 and 7 days) regimes. The results were compared to the routine seed quality tests, such as the standard germination test, first germination count, accelerated aging, electrical conductivity and emergence in the field. Tests were conducted in two seasons, four months apart. The results obtained using the various assays were compared by Tukey's test. Correlation analysis between the cold test methods and other vigor tests were carried out. Paper rolls without soil for a period of three to five days at 10ºC and 15ºC correlated better with the standard vigor tests, especially the first germination count and field emergence.
