Abstract: Very low doses of irradiation have been reported to cause stimulatory or hormesis effects on plants. Irradiating the seed has been reported to improve emergence, and this would be a benefit for valuable, field-seeded crops. Over 3 yr, irradiation significantly increased the first emergence counts of broccoli, by about twofold, and the time to 50% of final emergence was advanced by about 1 d. In 1 yr trials, 50% of final emergence was advanced by 3 d for parsnip, but there was no effect for cauliflower. After emergence was complete, all plots were thinned and there were seldom any significant hormesis effects on yield parameters.Key words: X-ray, emergence, vigor, ionizing radiation, cole crop
