Seed Invigoration: Treatments and Quantification of Vigour

Seed treatments for extending longevity of dry-stored orthodox seeds and maintenance of vigour and viability of seed lots and field performance potential of crops have been covered for commercial adaptation by the predominantly small and marginal farmers. The research findings are based on development of seed hydration-dehydration as well as 'dry' (non-aqueous) seed treatments in the University of Calcutta during the last over four decades involving a large number of post-graduate students, pre-and post-doctoral fellows and faculty members.
