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

Figure 4

The concentrations of total glucosinolates (a), total indole glucosinolates (b), and total aliphatic glucosinolates (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.
