Growth performance of rapeseed plants under the control and salinity conditions. (A-B) Growth performance of the shoots (a) and roots (b) in rapeseed plants under different dosages of salt conditions. c Shoot and root dry weight of the rapeseed plants under different NaCl concentrations. The uniform rapeseed plants after 7-day seed germination were grown under NaCl-free (control) for 10 days, and then were changed to the solution containing 0–250 mM NaCl for 5 days. Different lowercases indicate the significant differences at P < 0.05. (D-H) Root/shoot (R/S) ratio (d), leaf area (e), specific leaf weight (f), maximal root length (g), and root system architecture (h) under control and 200 mM NaCl conditions. For d-h, uniform rapeseed plants after 7-day seed germination were grown under NaCl-free (control) for 10 days, and then they were transferred to the solution containing 200 mM NaCl for 5 day. Data are means (±SD), n = 5. ns, not significant; *, P < 0.05; **, P < 0.01; ***, P < 0.001
