Figure 8.

Sodium concentration in non-germinating durum wheat seeds subjected to different salinity stress levels (1: MSS = 5 g L⁻¹ NaCl, 2: SSS = 10 g L⁻¹ NaCl). The significance of the differences is marked by the letters in the figures. Means with different letters are significantly different at α = 0.05 according to Fisher’s Least Significant Difference. The standard error of the mean of five replicates is represented by the bars on the columns. P0: non-primed seeds, P ZnSO₄: seeds primed with ZnSO₄, P KNO₃: seeds primed with KNO₃.
