Evaluation of wheat seed vigor by the accelerated aging and cold tests

This research was performed to study procedures for the accelerated aging and cold tests and to verify the efficiency of these tests to evaluate wheat (Triticum aestivum L.) seed vigor. Cold tests, with and without soil, and accelerated aging (traditional and saturated salt) were carried out, in wheat seeds 'IAC-350' and 'IAC-370', each represented by five seed lots of high germination (> 90%). Results were compared with germination tests carried out after storage under laboratory conditions. It was concluded that both procedures of the accelerated aging, at 43ºC/48h, were efficient to evaluate wheat seed vigor. The cold test, performed as the procedure developed for maize seeds, did not consistently detect differences in wheat seed vigor.
