Fig. 7. — Effect of PEG pre-treatment/treatment on La (A), Sr (B), and Rb (C) accumulation of 1 cm root tips in Al-sensitive common bean genotype (VAX 1). Plants were pre-treated without (–PEG) or with 150 g l⁻¹ PEG (+PEG) in a simplified solution (pH 4.5) containing 5 mM CaCl₂, 1 mM KCl, and 8 μM H₃BO₃ for 8 h. Then the plants were supplied with 5 μM LaCl₃, 2.5 mM SrCl₂ or 0.5 mM RbCl in absence (–/–, +/– PEG) or presence of 150 g l⁻¹ PEG (–/+, +/+ PEG) in the same nutrient solution as described above for 1 h. Bars represent means ±SD, n=4. Means with the same small letter and capital letter are not significantly different at P <0.05 (t test) for the comparison of PEG pre-treatments within PEG re-treatments and comparison of PEG re-treatments within PEG pre-treatments, respectively.
