The faveira bean (Parkia platycephala Benth.), belongs to the Fabaceae family, this species is recommended for afforestation and also has a forage potential. In addition, it has the potential of landscaping, the wood can be used for box-office, tables for internal divisions in small constructions, linings, confection of toys, as well as for firewood and charcoal. That way, the aim of this study was to evaluate the effect of different temperature and substrate on the germination of seeds of P. platycephala. The study was carried out at the laboratory for analysis of Seeds of the Department of Plant Science and Environmental Agricultural Sciences Center of the da Universidade Federal da Paraíba, in Areia PB. Therefore, a completely randomized design and a 6 x 4 factorial arrangement were performed, consisting of the combinations of six temperatures (25, 30 and 35 °C constant and 20-30, 20-35 and 25-35 °C alternating) and four substrates (sand, coconut fiber, paper and vermiculite). To evaluate the effect of the treatments were performed germination test, first count and germination speed index, length of plants, root and aerial dry matter. The constant temperature of 35 °C provided better performance of seeds Parkia platycephala when using the sand as substrate.
