Seeds collected in Lavras-MG- were submitted to the following methods of pre-conditioning: a) scarification and immersion in water of 25oC for 14 hours; and b) immersion in water of 95oC and left in the same water to rest without heating for 24 hours at 25oC. The teguments of the seeds were removed and the embryos were immerged in 0.07, 0.1 and 0.3% tetrazolium solution during 150 minutes at 25oC. To verify the reliability of the results through the tetrazolium test, germina  test, first counting, index of germination velocity and nursery emergency were done. Scarification and immersion in water of 25oC for 14 hours were efficient in pre-conditioning canafistula seeds and 0,1% tetrazolium solution for 150 minutes at 25oC allowed evaluating seed lots of this species.
