    • Figure 1. 

      The emergence of rapeseed and pea under different concentrations of salt and alkali stress (7 d after sowing).

    • Figure 2. 

      Growth of pea and rapeseed under different concentrations of salinity and alkali stress.

    • Figure 3. 

      The aboveground and root biomass of rapeseed and pea under different concentrations of salt and alkali stress. Note: NaCl concentration: 0.80% (S1), 1.00% (S2), 1.20% (S3), 1.4% (S4); Na2CO3 concentration: 0.05% (A1), 0.10% (A2), 0.15% (A3), 0.20% (A4), control (CK). Different lowercase letters indicate significant differences (LSD test, p < 0.05). (a) Pea shoot fresh weight. (b) Pea root fresh weight. (c) Rapeseed shoot fresh weight. (d) Rapeseed root fresh weight.
