Differential Responses of Two Broccoli (Brassica oleracea L. var Italica) Cultivars to Salinity and Nutritional Quality Improvement

Figure 2

Osmotic potential (Ψ_𝜋) of leaf sap (a) and root xylem sap (b) of broccoli plants grown under saline conditions (0, 30, 60, or 90 mM NaCl) for 15 days (n = 5 ± SE). The significance of the difference between the two cultivars was given according to the Student’s t-test, with ^∗𝑃<0.05, ^∗∗𝑃<0.01, ^∗∗∗𝑃<0.001; n.s: nonsignificant.
