The use of high physiological quality seeds is an essential in the establishment of any crop. Germination and vigor tests are required for seed quality control. The objective of this study was to evaluate the efficiency of the accelerated aging test in determining the vigor of crambe seeds. The initial quality of five lots of crambe seeds, cultivar FMS Brilhante, was assessed by determining the water content, germination, germination first count, seedling emergence index and emergence rate. For the accelerated aging test, the seeds were subjected to temperatures of 41 and 43 °C in a BOD chamber for 48, 72 and 96 hours. At the end of each aging period, the seeds were put to germinate according to the methodology for the germination test. The experiment was arranged in a completely randomized design with four replications per lot. The accelerated aging test under the condition of 41 °C for 72 h provided the greatest vigor discrimination between the lots of crambe seeds, cultivar FMS Brilhante.
