The effect of temperature and substrate on the germination of gliricídia (Gliricidia sepium (Jacq.) Steud) was studied in laboratorial conditions. Seeds were placed on towel paper, sand and vermiculite substrate. Seed germination was evaluated at 25°C, 30°C and 20-30°C. The results demonstrated that alternating the temperature between 20-30°C with sand, and 25°C for vermiculite were the best treatments with higher values than the others.
