Photosynthetic characteristics and anthocyanin concentrations in rapeseed plants under the control and salt conditions. a Effect of salinity on net photosynthetic rate (Pn, μmol m− 2 s− 1), stomatal conductance (gs, mol H2O m− 2 s− 1), intercellular CO2 concentration (Ci, μmol mol− 1), and transpiration rate (Tr, mmol H2O m− 2 s− 1) of the rapeseed plants under control and 200 mM NaCl conditions. b-d The SPAD values (b), photosynthetic pigment concentrations (c, d) and anthocyanin concentrations (e) in rapeseed plants under control and 200 mM NaCl conditions. Uniform rapeseed plants after 7-day seed germination were hydroponically grown under NaCl-free (control) for 10 days, and then they were transferred to the solution containing 200 mM NaCl for 5 days. Data are means (±SD), n = 5. Significant differences were determined using Student’s t-test: ns, not significant; *, P < 0.05; **, P < 0.01; ***, P < 0.001
