Na⁺ and K⁺ contents of shoots and roots in different treatments. Na⁺ and K⁺ were determined using an atomic absorption spectrophotometer and Na⁺ (A) and K⁺ (B) content (mg/gDW) were calculated with the shoots or roots dry weight in ST, N4, R3, and N7. Data were pooled from two independent repeats with n ≥ 6 at each point and values are means ± SE.
