This experiment was performed in order to evaluation antioxidant enzymes activity in seedling induced of milkthistle primed seeds in salt stress condition. The experiment was conducted in factorial based on completely randomized design with four factors and three replications in Agricultural Biotechnology Research Institute of Iran (ABRII). These factors were included of genotype (Amol and Majar), priming (primed and non-primed seeds), stress: salinity (150 mM) and control led (non-salinity) and time of sampling in 24 and 96 hours after sowing. The results showed the seed priming increased significantly the catalase (CAT) activity in Majar , proxidase(POX) activity in both genotypes and ascorbat peroxidase (APX) in Amol, so that CAT activity increased in Majar primed seeds than control 96%. Priming increased POX activity in Majar 14-fold greater than Amol. Increasing CAT and APX activity were observed in primed seeds in germination stage but POX activity increasing was observed in imbibition stage. Overall, the results showed the CAT, POX and APX activity was higher in primed seeds than non-primed in salt stress condition. Priming affected CAT and POX activity in Majar greater in Amol.
