Priming on seed quality 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 %). The results of the study showed that among the seed lots L1 has recorded higher seed quality parameters viz., germination (93.00 %) and seedling length (26.70 cm) compared to L2 (70.67 % and 19.30 cm). Among the various seed priming treatments KH2PO4 (1 %) is the suitable priming chemical to improve the marginal quality sunflower seed lots viz., germination (89.67 %), speed of germination (19.22), days to 50 % germination (2.15), seedling length (28.83 cm), seedling dry weight (64.44 mg) and seedling growth ratio (1.44) compared to control (81.83 %, 15.91, 2.74, 23 cm 55.03 mg and 1.20 respectively). Priming treatments are more effective in marginal seed lots compared to fresh seeds.
