After immersion, the seeds were dried in the shade and then were sown in washed sand in plastic trays of 30 x 20 x 10 cm without drainage. Trays without drains were selected to keep the fermentation products near the seeds during the test period. The trays were maintained in the greenhouse without temperature control; water was applied whenever it was necessary. Plantlets were collected, washed in running water, dried in tissue paper and weighed individually with a digital precision balance; root lengths were measured with a ruler. Plant counts were made daily. Analysis of variance and Tukey's Test were performed on the data (Ferreira, 1991).
