Figure 2

Effects of salinity and Si on chlorophyll a (a), chlorophyll b (b), total chlorophyll (c), and carotenoids content (d) in the two liquorice species. Data are presented as the mean ± SE (n = 3). Different letters indicate significant differences between the values for one index for the same liquorice species under different treatments (P < 0.05).
