The experimental design used was a completely randomized one in a 4 x 3 + 1 factorial arrangement (4 concentrations of tetrazolium solution x 3 periods of coloration + 1 control – germination test) at a temperature of 30 °C and the other one at 35 °C in four replications of 25 seeds for each treatment. The data were submitted to normality and homogeneity test of variances to assess the need for transformation.
