ABSTRACT
The objective of this study was to characterize morphometrically seeds, evaluate the treatments of scarification, and germination temperatures and the potential seed storage Triplaris Brasiliana Cham., a pioneer species, with great potential for recovery of degraded areas, permanent preservation, riparian areas and land. For the morphometric characterization, it was determined the length and thickness, mass of 1000 seeds, color, shape and hilum and micropyle location, such embryos, the location and type of germination. The germination test was evaluated from seeds with and without scarification at different temperatures. The storage was tested in glass and paper packaging and in refrigerator, dry chamber and ambient conditions. The embryo is axial, and the embryonic axis in the central part of the seed of the lower half, the germination is epigeal and the seedlings are fanerocotylar. Sowing the seeds scarified on paper subjected to 30 °C were more favorable for germination and development of Triplaris brasiliana seedlings, and seeds sensitive to dehydration (intermediate), while preserving physiological quality for longer when stored in the refrigerator and camera in the packages used.
