This research aimed to study procedures for conducting the accelerated aging test to determine the physiological potential of wheat seeds. The experiment was conducted with four varieties: 'Pampeano', 'Sapphire', Onyx' and 'Jasper'. Tests were performed with water content, germination, seedling emergence, speed of emergence and accelerated aging. The accelerated aging test was conducted in three stages: traditional (water), test using saturated NaCl solution (11g of NaCl per 100mL of water) and with the use of supersaturated solution of NaCl (40g of NaCl per 100mL of water), each for 48, 72 and 96h at 42 degrees C. The accelerated aging test with saturated solution of NaCl, within 96h was suitable to evaluate the physiological potential of seeds of wheat in high, medium and low vigor.
