Information about the feasibility and adequate substrates for the germination of seeds from native arboreous species are scarce. Cordia glabrata (louro preto), a pioneering species with wide distribution, is included among these species. Its characteristics allow its use in ornamentation, apiculture and popular medicine. Considering its potential of utilization, this work had as objective to evaluate the germination rates, in different substrates, of recently reaped seeds stored for up to 120 days in laboratory, which were collected in Pantanal of the Rio Negro, Mato Grosso do Sul State. Tests were done with recently reaped seeds and after 30, 60, 90 and 120 days of storage, in three kinds of substrate (paper filter, sandy soil and sandy soil + organic matter). The results revealed that C. glabrata has a small percentage of water (1.55%) in the seeds, which decreases with the storage period. Its feasibility period is short (90 days) and the best results were obtained with recently reaped seeds germinated in paper filter (34%), with a germination speed rate of 10.
