Root elongation rate (A) and callose contents in the 1 cm root tips (B) of the common bean genotype VAX 1 as affected by soil moisture and Al supply (g kg⁻¹ soil). Two-day-old seedlings were grown in soil for 24 h. Bars represent means ±SD, n=12 for A, and n=4 for B. Means with different lower and upper case letters are significantly different at P < 0.05 (Tukey test) for the comparison of Al treatments within soil moisture and comparison of soil moisture treatments within Al treatments, respectively. For the ANOVA, *** denote significance at P < 0.001.
