November 2013   Abstract   This experiment was conducted to evaluate the effects of NaCl priming on
growth traits and some biochemical attributes of safflower (Carthamus
tinctorius L. cv Safola) in salinity conditions. 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).
