Figure 2.

Effect of Al (50 μm) on the Al accumulation at 2-mm specific segments (A) and in the total root (10-mm) apex (B) of squash plants after 3- and 6-h Al treatments. Al was not detected in control root apices. The Al contents were determined either in three replicates, each comprising three 10-mm root apices for the total apex or in five replicates each comprising five 2-mm segments of the same distance from the tip (DFT) position. Values are mean ± se and representative of at least two independent experiments.
