The aim of this work was to evaluate the influence of germinative pretreatments (control; chloridric acid, for 3 min; longitudinal cuts without and with water soaking) and substrates (sand and coconut fiber) in the germination of Platypodium elegans Vog. seeds. The analyzed characteristics were: percentage of germination, first germination count, germination speed index, length and dry mass gain to seedlings. There was no significant difference for the germination percentage (x = 51%), but the longitudinal cuts promoted higher indices of germination speed (x = 0.95) and first germination count (x = 42%). The coconut fiber and the longitudinal cuts induced greater length (x = 13.5 cm) and dry mass gain (x = 50.0 mg) in the seedlings.
