FIGURE 4.
Ion content in maize inbred lines TL1317 and SL1303 seedlings following 150 mM NaCl treatment. Na+, K+, and Na+/K+ ratios in roots (A,E,I), stems (B,F,J), young leaves (C,G,K), and old leaves (D,H,L). Three-leaf-old seedlings were treated hydroponically and supplemented with 150 mM NaCl. Bars represent the mean (three replicates with each replicate containing 10–20 plants) ± standard deviation.
