The vigor and germination tests are essential components of seed quality control for the seed industry. Accelerated aging is one for the most useful tests used for the evaluation of seed vigor. In this sense, this paper aimed to study the methodology of the accelerated aging test, in order to identify different levels of vigor seed lots of okra (Abelmoschus esculentus (L.) Moench). Four seed lots of the 'Colhe Bem' cultivar and five seed lots of the 'Santa Cruz 47' were submitted to the following assessments: germination, seedling emergence, accelerated aging by traditional procedures and saturated NaCl (38 and 41°C for 24, 48, 72 and 96 hours) and moisture content at the beginning of the tests and, after incubation to accelerated aging test. The accelerated aging test at 41°C/96 hours (traditional procedure and saturated NaCl) consisted efficient to detect vigor differences among seed lots of okra.
