Abstract
Abstract: 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.
Highlights
There are approximately 47 million hectares of natural pasture and 112 million hectares of planted pasture in Brazil
It is important to evaluate seed vigor to complement the information provided by the germination test

Summary
There are approximately 47 million hectares of natural pasture and 112 million hectares of planted pasture in Brazil. Seed quality is fundamental for obtaining an adequate and uniform stand (Costa et al, 2011). For evaluation of this quality, the germination test is the official procedure that evaluates the capacity of seeds to produce normal seedlings under ideal conditions. This test does not always reveal differences of performance between seed lots during storage or in the field (Carvalho and Nakagawa, 2012). It is important to evaluate seed vigor to complement the information provided by the germination test
