Figure 4From: Variations in osmotic adjustment and water relations of Sphaerophysa kotschyana: Glycine betaine, proline and choline accumulation in response to salinityEffects on osmotic potential (Ψ Π , MPa) in S. kotschyana leaves (A) and roots (B) exposed to 0 (Control), 150 mM and 300 mM NaCl for 7 and 14 d are shown. Vertical bars indicate ± SE and values sharing a common letter are not significantly different at P > 0.05.Back to article page
