Seeds of safflower were primed with NaCl (5 g L-1) for 12 h in 23 °C. Primed (P) and non primed (NP) seeds were directly sown in the field. Experiments were conducted using various water concentrations induced by NaCl (0, 3, 6, 9 and 12 g L-1) in salinity experiment. Results showed that growth (plant height, fresh and dry weight) and biochemical (chlorophyll, proline and proteins content) of plants derived from primed seeds were greater of about 15 to 30% than that of plants derived from non primed seeds. It seems that salinity tolerance in priming resulted plants was due to higher potential of these plants to accumulate more biochemical attributes (more chlorophylles, proline and proteins in primed plants than controls ones).
