that could meet Na+ higher concentration and controlled the Na+/K+ and Na+/Ca+ ratios. On the other hand, although Si could reduce Na+ absorption due to salinity, it could not enhance the absorption of K+ or Ca+2. So, the small concentration of Na+ absorbed has led to higher ratios of Na+/K+ and Na+/Ca+ compared to the control treatment. Plants treated by SA showed higher concentrations of most cations especially Na+ resulting in higher ratios of Na+/K+ and Na+/Ca+ compared to the control treatment
