Cupania vernalis Cambess. seeds have a short longevity with a recalcitrant behavior when submitted to drying. This demands development and adoption of technologies to improve storage and conservation of the seeds. Thus, the objective of this work was to evaluate physiological aspects of Cupania vernalis seeds at different storage temperatures and to different seed moisture content. Seeds with 40%, 35% and 30% of water content were conditioned in plastic bags and stored at 10ºC and 25ºC under controlled temperature and relative humidity around of 60%. During 0, 120 and 240 days of storage seeds were taken for evaluation of water content, germination, emergency index. The treatments in which seed contained moisture content of 40% and stored at temperature of 10ºC helps the conservation of seeds of C. vernalis.
