N2  - Maximum  germination  percentage  achieves  immediately  after  harvesting  and  gradually de#creases with storage time. Aging is one of the key factors in plant yield loss especially in vegetables. Seed aging is the main problem of seed storage. Application of accelerated aging treatment is used to assess seed vigor and quality. Seed priming enhances seed germination performance after aging. An experiment was conduct in order to investigate the activity of catalase  and  ascorbate  peroxidase  during  accelerated  aging  and  repair  during  priming treatment  of  sesame  (Sesamum  indicum L.)  seeds.  In  order  to  improve  germination characteristics  in  aged  seeds  with  seed  priming.  Our  result  showed  that  seed  priming treatments significantly (p≤ 0.01) affected, germination percentage, germination Index and normal seedling percentage after aging (0, 3 and 6 days). Increasing aging duration resulted higher reduction in germination characteristics. Priming with gibberelic acid (GA) increased germination characteristics of seed aged. The highest germination percentage, germination index, normal seedling percentage and enzyme activity were achieved in control conditions (0 day of aging). Also antioxidant activity of aged seeds increased after seed priming.
