ABSTRACT
The study aimed to evaluate the germinative potential of native forest species in south of Piauí in different cultivation environments. Four species native to Brazil (jatobá, faveira, white angico and ipê purple) were subjected to treatments that consisted of two distinct environments (Biochemical Oxigen Demand - BOD and forest nursery). Were analyzed: germination percentage, germination speed index, average germination time and seedling fracture. BOD germination chamber allows greater germination potential for faveira, white angico, ipê and jatobá species, with a greater germination percentage and germination speed index of germinated seeds. However, germination potential of the jatobá is reduced under nursery environment. Moreover, Ipê seeds display low germinative potential as compared to other studied species, for all investigated environments.
