Abstract

Pre-storage dry seed invigoration treatments of freshly harvested urdbean seeds (Vigna mungo L. Hepper, cv. Sarada) with aspirin, bleaching powder, iodinated calcium carbonate and red chilli powder showed siginificantly improved post-storage germinability, field performance and productivity of the crop over control. However, pre-storage wet treatments did not show any beneficial effect on storability and field performance over control. Physiological and biochemical studies indicated higher membrane integrity and greater enzyme activity of the dry treated seeds than untreated control. The lipid peroxide formation and volatile aldehyde production were also significantly lower in the treated seeds than in control. Thus, pre-storage dry treatments may be suggested for the improvement of storability and field performance of urdbean seeds.
