The study aimed was to determine the effects of drought stress (0, -4, -8, -12 bar) and osmo-priming (-15 bar PEG 6000 for 15 at 24 h) on seed germination, seedling growth and enzyme activity at different temperatures were assessed in the laboratory for wheat. Results showed that the highest germination percentage (GP) (94.33%), normal seedling percentage (NSP) (92%), germination index (GI) (44.85) and seedling length (11.03 cm) were attained from osmo-priming in control conditions. Therefore, seed priming with PEG 6000 significantly (p≤ 0.01) increased germination characteristics as compared to the unprimed seeds under drought stress. Also, osmo-priming increased catalase (CAT) and ascorbate peroxidase (APX) as compared to the unprimed.
