Effect of TEB and TRI on ion homeostasis: Na+ content (A), K+ content (B), K+/Na+ ratio (C), Ca2+ content (D), and Mg2+ content (E) in the shoots and roots of 10-day-old wheat seedlings under salt stress. TT and S indicate 1.375 µM TEB + 0.5 µM TRI and 250 mM NaCl, respectively. Means (± SD) were calculated from three replicates for each treatment. Bars with different letters are significantly different at P ≤ 0.05 applying Fisher’s LSD test
