Effect of phosphorus and salinity on the concentration of shoot P, K, Na, and K⁺/Na⁺ in maize.

P supply	Salinity	Shoot P concentration (μmol g−1 DW)	Shoot K+ concentration (μmol g−1 DW)	Shoot Na+ concentration (μmol g−1 DW)	K+/Na+
High P	−NaCl	222.46 ± 11.42b	1377.51 ± 16.43a	n.d.	–
	+NaCl	271.27 ± 6.94a	1015.39 ± 21.98b	486.70 ± 5.98a	2.09 ± 0.06b
Low P	−NaCl	30.01 ± 0.76c	1311.01 ± 7.32a	n.d.	–
	+NaCl	31.06 ± 1.33c	1098.73 ± 11.30b	215.31 ± 14.26b	5.17 ± 0.12a

The values are mean ± SE (n = 4). Different letters within each column denote significant differences (P ≤ 0.05) between treatments. n.d.: not detected.
