Studies were undertaken at the Department of Seed Science and Technology, Tamil Nadu Agricultural University, Coimbatore
using different seed lots of black gram cv. CO 6 with a view to elicit information on seed invigouration for maintenance of
seed quality during the storage period. Seeds soaking followed by drying for different durations ranging from 1h, 2h and 3hwith different inorganic chemicals viz., Vitamin E (- tocopherol), Para Amino Benzoic Acid (PABA) and Salicylic Acid
at concentrations of 2.5 mM, 5.0 mM and 7.5 mM in 1:1 seed to solution ratio was attempted. The results show that
soaking of varying seed lots of freshly harvested, aged treated and treated aged seeds of black gram (3 days of accelerated
ageing) in low concentrations viz., 2.5 mM, 5.0 mM of salicylic acid followed by drying was effective in controlling seed
deterioration and improving seed vigour and viability in all the seed lots.
