Salinity mediated inhibition of seed germination and seedling emergence are the main problems in saline areas. An investigation was carried out to evaluate the effect of four different concentrations (10^-5, 10^-7, 10^-9 and 10^-11 M) of pre-soaked 24-epibrassinolide (24-EBL) on the germination traits associated with seedling emergence in Vigna Mungo (L). Hepper under salt stress. The results revealed that salinity significantly reduced germination traits especially at higher doses of 16 and 20 dsm¹. Radical length, plumule length, radical fresh weight, plumule fresh weight, germination percentage, seedling length, seedling fresh weight and the seed vigour index also decreased with increasing salinity but seeds primed with 24-EBL alleviated the effect of salinity. Under both stressed and non-stressed conditions, 10-5M 24-EBL was found to be most significant, while 10-11 M 24- EBL was least significant.
