Temperatures and periods of drying delay and quality of corn seeds harvested on the ears
Abstract: Seeds harvested on the ears have high moisture content. On that account, this study aimed at evaluating the loss of physiological quality of corn seeds harvested on the ears, as a function of different drying-delay times. Hybrid corn ears were harvested at 31% moisture and then had their d...

| description | Abstract: Seeds harvested on the ears have high moisture content. On that account, this study aimed at evaluating the loss of physiological quality of corn seeds harvested on the ears, as a function of different drying-delay times. Hybrid corn ears were harvested at 31% moisture and then had their drying postponed for 0, 12, 24 and 36 h, while subjected to temperatures of 30, 40, 50 and 60 °C. The physiological quality was evaluated after 0, 4, 8 and 12 months of storage. A completely randomized design was employed, in a 4 x 4 x 4 factorial scheme, with four replications. In addition, a study was performed in a seed-processing unit, reporting the average waiting time before drying and the temperatures of all loads of a corn hybrid received at the facility. The physiological quality was not affected by temperatures below 40 °C, considering 36 h of waiting before drying. At 50 ºC during the drying delay, the germination was impaired 36 h afterward, and the vigor was compromised after 24 h, with the damage effects intensifying as the storage advanced. At the temperature of 60 ºC, the deficits in germination and vigor occurred within the first hours of drying delay. |
