Figure 2.

Effect of NaCl stress on different photosynthetic pigments. Plants of Brassica juncea (black bars) and Brassica napus (grey bars) were exposed to either 0 or 300 mM NaCl and concentrations of different photosynthetic pigments, including chlorophyll (a) and carotenoids (b), and the ratio of chlorophyll a/b (c) was measured after 15 days. Data points represent the means ± SD of three biological replicates. Significant differences are shown with different asterisks (***, ** at p = 0.001, 0.01, respectively).
