Abstract
An experiment was conducted in pots to study the effect of sodium chloride levels (0,50,100,and 150)meg.L-1 on two wheat cultivars AL-Hussein and AL-Rasheed in terms of germination percentages, seedling vigour index, lengths and dry weights of shoot and root, phytotoxicity of shoot and root, stress intensity, stress tolerance index, electrolyte leakage percent and chlorophyll stability index. Salinity treatments were applied from sowing till the end of the experiment. Factorial experiment with CRD design with three replicates was used. Results revealed that, AL-Hussein cultivar gave the highest response to salinity compared with AL-Rasheed in terms of germination percentage., seedling growth, shoot and root dry weights, seedling vigour index, stress tolerance index and chlorophyll stability index. Meanwhile, AL-Rasheed cultivar gave the highest values of shoot and root phytotoxicity stress intensity and electrolyte leakage percent. Sodium chloride significantly affected all studied characteristics, but the highest (level 150 meg.L-1) gave higher increase or decrease in studied characteristics compared with the control. These results indicated that, tolerance of AL-Hussein cultivar to salinity was correlated with stress tolerance index and chlorophyll stability index under salinity stress.
