Priming on biochemical changes was tested on two seed lots L1: Fresh seeds (> 91 % Germination) and L2: Aged seeds (< 70 % Germination). The seeds were treated with priming chemicals 12 hours of soaking viz., C1: Control, C2: Hydropriming, C3: KH2PO4 (1 %), C4: GA3 (400 ppm), C5: NaCl (1 %), C6: KCl (2 %), C7: KNO3 (2 %), C8: CaCl2.2H2O (2 %), C9: PEG (-1Mpa), C10: K2HPO4 (1 %). Among the various seed priming treatments KH2PO4 (1 %) is the suitable priming chemical to improve the marginal quality sunflower seed lots viz., higher total dehydrogenase activity (OD@ A480nm) (0.909), α -Amylase activity (mg maltose liberated min-1 g-1) (0.530), Peroxidase activity (ΔA436 nm min-1 gram-1) (0.732) and lower electrical conductivity (1.722 dSm-1), as compared to control (0.568, 0.258 and 1.722 dSm-1 respectively). Priming treatments are more effective in marginal seed lots compared to fresh seeds.
