Interactive effects of NaCl and pH on shoot fresh weight (A), root fresh weight (B), shoot length (C), and root length (D) of canola seedling 7 days of germination. S is salinity, P is pH, and S × P is their interaction, *, **, and *** indicate significance at P = 0.05, 0.01, and 0.001, respectively, according to the least significant difference (LSD) test for simple effects analysis of two-way ANOVA interactions (P < 0.05).
