Effect of Cd(II) on root and shoot growth. A Root growth in the plants grown in the MS solid media with 0, 10, 25, 50, and 100 mg/L of CdCl₂ for 7 days. B Quantification of root length of these plants (n > 50). C Shoot growth in the plants grown in the MS solid media with 0, 10, 25, 50, and 100 mg/L of CdCl₂ for 7 days. D Quantification of leaf length in these plants (n > 50). Error bars indicate SD. Asterisks indicate statistically significant differences between the corresponding samples and their control (p value < 0.01, t-test). Scale bars = 0.5 cm
