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

Figure 5

The concentrations of chlorogenic acid derivates (a), flavonoids (b), and sinapic acid derivates (c) in the shoots of broccoli plants grown under saline conditions (0, 30, 60, or 90 mM NaCl) for 15 days (n = 5 ± SE). Column values with the same letters are not significantly different (𝑃<0.05, Tukey’s test). 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.
