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.
