摘要：

Seeds of five forest species were classified according to their physiological storage behavior. Seeds of Casearia sylvestris Swart (Salicaceae), Qualea grandiflora Mart. (Vochysiaceae), Guarea kunthiana A. Juss. (Meliaceae), Eremanthus incanus Less. (Asteraceae), Protium heptaphyllum March. (Burseraceae) were collected and taken to the laboratory, where they were processed and submitted to both rapid and slow drying, storage and assayed for viability. After physiological classification regarding storage behavior, it was observed that seeds of C. sylvestris and E. incanus presented orthodox behavior. Seeds of G. kunthiana and P heptaphyllum were classified as recalcitrant and Q. grandiflora as an intermediate, which did not tolerate low moisture content.
