Two experiments were conducted: experiment I-two soybean seed lots of the cultivars BR-30 and BR-16 were submitted the six periods of imbibition under four temperatures; experiment II-three seed lots of fiscalized soybean seed of the cultivars Davis, BR-29 and BR-24 were submitted to seven periods of imbibition at 25.C In a general manner, it was observed that the seeds of the cultivars BR-30 and BR-16 reached 37% seed moisture content after 10h/40.C the preconditioning period. This moisture content, resulted in adequate staining patterns for determining vigor [TZ (1-3)] and viability [TZ (1-5)] for tetrazolium test in soybean seed. atemperature aSemente aSoja aTeor de Umidade aTeste de Tetrazólio aMoisture content aSeed aTetrazolium test1 aMARCOS FILHO, J. tArquivos de Biologia e Tecnologiagv.37, n.3, p.693-701, set. 1994.
