摘要：

Corn seeds were harvested with 16% and 21% of moisture content and dryed for 0, 12, 24, 36, 48, 72, 84, 96, 108, 120, 132, 144 e 156 hours after harvest to verify the effect of delaying desiccation on germination and vigor. The results pointed out that to obtain seed germination over 85%, seed drying may be retarded up to 84 hours when seeds were harvested with 21% of moisture content. The physiological quality of seeds decreased significantly when seed drying was retarded for more than 84 hours after harvesting seeds with high moisture content (21%). The physiological quality was not affected when seeds were harvested with low moisture content (16,0%) and desiccated up to 156 hours.
