Sunflower seed (SunGro 380) were harvested 101 to 121 days after planting, and their moisture levels were between 43 and 15%. The seed were dried at 35, 53, 72, and 88 C to a final moisture level of 10% or below. Drying air flow was 2000 m 3 /hr./m 3 seed. Temperature had no effect on peroxide values, total oil, or fatty acid composition. Free fatty acids increased as initial moisture decreased. For a given drying temperature, germination increased with decreasing initial moisture, and for a given initial moisture, germination increased with decreasing drying temperature. This study indicates that a drying temperature greater than 53 C should not be used if seed viability is to be maintained.
