This research was carried out to study procedures for the germination test in sansão-do-campo seeds (Mimosa caesalpiniaefolia Benth.). The first study was done on a thermo-gradient table with temperature varying from 15°C to 35°C and daily 8-hour photoperiod. The best temperature from the first study (30°C and 35°C) was then evaluated in two substrata (paper - on top of paper and paper rolls, and vermiculite - between vermiculite). Evaluations were performed daily, according to the criteria established in the Brazilian Rules for Seed Testing, and the percentage and germination speed were determined. The best temperature was 30°C distributing the seeds using paper or vermiculite.
