Determination of Germination Parameters of Safflower (Carthamus tinctorius L.) Cultivars Under Salt Stress

The present study was carried out to characterize germination capacity of 10 safflower cultivars under saline conditions. Five salt (NaCl) levels (0, 60, 120, 180, 240 mM) were used test seeds. Germination seeds counted every day for 14 days and percentage, Timson’s index, mean time, rate stress index calculated. Cultivar salinity treatments important all parameters; however time interactions not important. indices decreased significantly with increased concentrations. However, higher most significant reductions in percentage observed at 180 mM Correlation coefficients indices. Based on indices, Leed FO2 more sensitive stage Royal resistant than the other tested. better assess Mean suitable differences parameters
