The aim of this study was to adjust the accelerated aging test to evaluate the

physiological potential of seed lots of Brachiaria brizantha ‘Xaraés’, represented by four

lots. Seeds were tested by traditional accelerated aging and with saturated NaCl solution in

five aging periods: 0, 24, 48, 72 and 96 hours. The profile of the lots was determined by the

following measures: moisture content, germination test, first germination count, germination

speed index, initial stand, emergence, and emergence speed index. The accelerated aging

test makes it possible to separate the lots by the method of saturated NaCl solution for 24

hours and it is appropriate for evaluation of seed physiological potential.
