Resumo: This work evaluated germination of faveiro (Dimorphandra mollis Bth) seeds under the effects of storage, pregerminative treatments and environment of incubation. Sowing occurred right after harvest and 90 days after storage under refrigeration. Seeds received the following pre-germinative treatments: 1) H2SO4 / 10 minutes; 2) H2SO4/ 20 minutes; 3) Acetone / 20 minutes; 4) slow cooking at 37°C for 24 hours; 5) control. Sowing occurred in gerbox boxes and they were kept in BOD germination chamber at temperatures of incubation at 20/30°C and 25°C at greenhouse. For each date of sowing, the experiment was carried out in complete randomized design in which were used 3 x 5 factorial schemes. Three replications of 20 seeds were used and total germination percentage and speed index of germination were evaluated. Sowed seeds right after harvest showed higher index of germination when they were treated with acetone for 20 minutes (53%) and sowed at 25% or at greenhouse (51%). After 90 days of storage, the best percentage of germination was observed in temperatures of 25 and 20/30°C (35.5 44.4%), although the higher speed index of germination had been observed at greenhouse and in seeds that were treated with H2SO4for 10 minutes and with acetone for 20 minutes (1.4). After 180 days the germination was loss in slow cooking (1,7%) did not vary among the treatments, (average of 20%) and 0,39 for speed index of germination. After 300 days higher germination and speed index of germination was observed in H2SO4 / 20min + GA treatment (41% e 4,67 respectively). The seeds showed loss in germination during evaluations.
