Abstract:

Seed aging is one of the major issues in the storage of seeds. This experiment was conducted to evaluate the effects of accelerated aging on sunflower seed germination indexes and enzyme activity. Seeds were incubated in closed plastic boxes for the accelerated aging treatments. Three accelerate aging regimes were performed by placing the sunflower seeds at 40°C and 90 % relative humidity for 0, 2, 4, 6 and 8 days. When aging duration increased, there was a reduction in the germination characteristics and increase in the activity of catalase and ascorbate peroxidise enzymes. The percentage of germination, mean time to germination, germination index, normal seedling percentage and enzyme activity decrease significantly with accelerated aging. The effect of priming treatments on the parameters such as percentage of germination, germination index, general normal seedling percentage and mean time to germination, under conditions provided for aging were significant (P
