Abstract
Corn is a cereal of great economic and social importance worldwide. The objective of the present work was to evaluate the effects on the physiological quality and the performance in the field of corn seeds with different quality standards before and after hydropriming with ozone. To evaluate the effects on the physiological quality, two batches (one with high physiological quality and the other with low physiological quality) of corn seeds were used. Seeds from both batches were immersed in distilled water and bubbled with atmospheric air (control - 0 mg L-1) or ozone. Three inlet concentrations of ozone (0, 10, and 20 mg L−1) and five periods of preconditioning (0, 30, 60, 90, and 120 min) were used. To evaluate the physiological quality of the seeds, different tests were carried out both in the laboratory and in the field. The use of the corn seed hydropriming with atmospheric air or ozone favored the physiological quality of the corn seeds when considering laboratory and field variables. There was an increase of emergence in the field of seeds not submitted to aging (high physiological quality) only due to the preconditioning period. The use of ozone was positive in lowering the loss of cellular solutes in seeds submitted to aging. Ozonation also caused significant increases in the plant heights and in the first ear insertion height. The binomial 20 mg L−1/60 min is the most suitable for preconditioning corn seeds in ozonated water.
