Resumo: The vigor tests are essential in programs of quality control of seeds, and the accelerated aging test is one which can be used for this purpose. 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 coriander (Coriandrum sativum L.). To do so, four cultivars (Português, Super Verdão, Taboca and Verdão), each represented by three lots of seeds, they were subjected to the following assessments: germination, first count of germination, seedling emergence, speed of emergency seedling height, dry mass of the aerial part of the of seedlings, accelerated aging by traditional procedures and saturated NaCl (38 and 41°C for 48, 72 and 96 hours) and moisture content at the beginning of the tests and, after incubation to accelerated aging test. The statistical design was completely randomized in a factorial 3 x 2 x 3 (lot x temperature x aging period), with four replications for each cultivar and test. The accelerated aging test at 41°C/48 hours (traditional procedure) and 41°C/72 hours (saturated NaCl) was sensitive to evaluated of physiological potential of coriander seeds.

Nesse sentido, a pesquisa teve como objetivo estudar a metodologia do teste de envelhecimento acelerado, visando à identificação de diferentes níveis de vigor de lotes de sementes de coentro (Coriandrum sativum L.). Para isso, quatro cultivares (Português, Super Verdão, Taboca e Verdão), representadas por três lotes de sementes cada, foram submetidas às seguintes avaliações: germinação, primeira contagem do teste de germinação, emergência de plântulas, índice de velocidade de emergência, altura de plântulas, massa da matéria seca da parte aérea da plântula, envelhecimento acelerado pelos procedimentos tradicional e em solução saturada de NaCl (38 e 41ºC durante 48, 72 e 96 horas) e grau de umidade no início dos testes e, após a incubação para o teste de envelhecimento acelerado. O delineamento estatístico utilizado foi o inteiramente casualizado, no esquema fatorial 3 x 2 x 3 (lote x temperatura x período de envelhecimento), com quatro repetições para cada cultivar e teste. O teste de envelhecimento acelerado no procedimento tradicional a 41ºC/48 horas e em solução saturada de NaCl por 41ºC/72 horas, apresenta sensibilidade para avaliação do potencial fisiológico de sementes de coentro.
