ABSTRACT: The vigor tests are intended to monitor the quality of seeds as it allows reliably distinguish lots of low and high vigor, providing additional information to the germination test. So in this study the objective was to identify the most efficient vigor tests on stratification of lots of corn seeds cv. 'Sertanejo'. The experiment was conducted at Laboratory of Seed Analysis at the Center of agricultural Science of the Universidade Federal da Paraíba, using samples from 20 seed lots in a completely randomized design. For characterization of the lots it was evaluated water content, germination and vigor (cold test, electrical conductivity, accelerated aging, seedling emergence in field and germination at low temperatures). The accelerated aging, electrical conductivity and field emergence of seedlings tests are the most efficient for classification of lots of corn seeds cv. 'Sertanejo' in levels of vigor, been the seeds of lot 1 the most vigorous.
