The Talisia esculenta (Cambess.) Radlk., Family Sapindaceae, is native to the Amazon, widely distributed in the Northeast of Brazil, where it has significant economic and ecological potential. However, there are no storage technologies for prolonged periods of its seeds. This study aimed to evaluate the physiological quality of stored seeds of Talisia esculenta submitted to different drying periods. The seeds were dried for 0, 6, 12, 18, and 24 hours and stored in the refrigerator for up to 60 days. A completely randomized experimental design was used, with treatments distributed in a 5 x 7 factorial scheme (drying and storage period), in four replications of 25 seeds. The moisture content, percentage of emergence, first emergence count, emergence speed index, length, and dry mass of seedlings were evaluated. The viability and vigor of the seeds decreased during storage according to the drying period. Seeds stored with moisture content between 39.88 and 41.40% remain viable and vigorous for 40 days. However, those stored with 45.70% moisture content lose viability and vigor after 20 days of storage.
