Abstract

The objective was to classify, as to the vigor, lots of creole seeds of corn through the emergency tests and emergency speed index. Fifteen batches of Creole maize purchased in seven regions of Oeste Potiguar were taken. The emergency was carried out in a greenhouse with four replications of 50 seeds, sown in a sand substrate, packed in 128 cell polypropylene trays. The substrate was moistened with distilled water at a capacity of 60%. The evaluation was carried out seven days after sowing. The emergence speed index was conducted concomitantly with the greenhouse emergency test, with daily counts being performed, from the appearance of the coleoptile on the substrate surface. The emergency tests and the emergency speed index stratified the Creole corn seed lots at two vigor levels.
