Abstract
Soaking-drying treatment of rice seeds (Oryza sativa L. var. Amber 33) significantly reduced the loss of vigour and viability under accelerated ageing conditions. This was with 12 month seed. The beneficial effects of this pretreatment were associated with significant increase in protease activity, which may reneet a curative effect. Thus, the age-induced damage to the cellular components could be enzymatically repaired. However, similar pretreatment of fresh, 2-month-old seed caused deleterious effect as compared to untreated seeds
