Abstract: The seeds of thirteen varieties of Pearl millet (Pennisetum glaucum (L.)) were evaluated for biochemical changes in response to sulphate base salinity. Sterilized seeds were kept in filter paper lined Petri dishes and irrigated with water or salt solution (00, 40, 80, 120 m.eq/L). These Petri dishes were kept for germination at 28 ± 2 OC in seed germinator. Care was taken to see that the filter paper remained moist by periodic additions of water or salt solution as per treatments requirement. The present study was carried out on sulphate dominant salinity. Embryonic axis (including cotyledons) of one and four day old seedlings were used for the estimations of physiological, biochemical, enzyme study by using the standard methodology or standard biochemical techniques. Sulphate dominant salinity levels reduced the per cent of germination of pearl millet, vigour index, root length, shoot length and increase osmolytes or solutes like total soluble sugars, true protein and glycine betaine. Differences in sensitivity to salt in pearl millet varieties are reflected by thirteen varieties of pearl millet. It was observed that cv. GHB-744, GHB-577 and GHB-1126 gave higher response in sense of physiological constituents, osmolytes or solutes, enzyme activity against salt stress. It suggested those that varieties have higher tolerance capacity against salt stress while other pearl millet varieties GHB-905 GHB-935, GHB-1120, GHB-1132, GHB-1138, GHB-757, GHB-538, GHB-719, GHB-732 and GHB-557 were found moderately tolerant or slightly susceptible against salt stress.
