Fig. 2. Dry weight and rhizosphere pH of seedlings grown in orchid agar treated with 15 µM Cd for the 2-wk experiment (A) and the 5-wk experiment (B). Dry weight and total cadmium of seedlings grown in orchid agar for the 2-wk experiment (C) and the 5-wk experiment (D). Cadmium concentrations (µg Cd g^-1 plant, dry wt.) and rhizosphere pH for seedlings grown in orchid agar for the 2-wk experiment (E) and the 5-wk experiment (F). Cadmium uptake and rhizosphere pH of seedlings grown in orchid agar for the 2-wk experiment (G) and the 5-wk experiment (H). Linear regression, ANOVA results: (A) R² = 0.42, Prob > F = <0.0001; (B) R² = 0.11, Prob > F = <0.0047; (C) R² = 0.27, Prob > F = <0.0001; (D) R² = 0.33, Prob > F = <0.0001; (E) R² = 0.44, Prob > F = <0.0001; (F) R² = 0.06, Prob > F = <0.0514; (G) R² = 0.66, Prob > F = <0.0001; (H) R² = 0.14, Prob > F = <0.0016.
