With the purpose of evaluate the effects of the osmoconditioning and hydration-dehydration treatments on physiological quality and storage potencial of okra seeds, a work was carried out. Three okra seed lots were submitte to the following treatments: hydration in water humid towel for eight and 16 hours, and osmotic conditioning at 25oC, in PEG 6000 solutions at -0,8MPa and -1,0MPa, during 48 hours. The evaluation was made soon after conditioning and after 3, 6 and 9 months of storage, by the standard germination test (first count and final count), accelerated aging, and speed of emergence index. The treatments showed similar effects. Priming treatments were efficient in restricting seeds water uptake. Seed vigor was decreased starting from the sixth month of storage.
