Fig. 2From: Comparative metabolic responses and adaptive strategies of wheat (Triticum aestivum) to salt and alkali stressEffects of salt stress (SS) and alkali stress (AS) on the contents of metal elements and free ions in wheat seedling leaves and roots. Metal elements Na (a), K (b), Ca (c), Mg (d), Fe (e), Cu (f), Zn (g), and Mn (h); free ions Cl− (i), NO3 − (j), H2PO4 − (k), and SO4 2− (l). Values are means of five replicates. Means followed by different letters in the same stress type are significantly different at p < 0.05 according to Duncan’s methodBack to article page
