Effect of Al supply (90 μm Almono, 1 h) to the entire root apex or specific 1-mm apical root zones on partial elongation rates of apical 1-mm root segments of the primary roots of the maize cv ATP-Y (Al-resistant) and cv Lixis (Al-sensitive). Values are means of five independent measurements ± sd. The results shown are representative of two independent experiments. Different letters indicate significant differences at P < 0.05 (Tukey's test). ●, Control (Al); ○ 0 to 1 mm zone; ▾, 1 to 2 mm zone; ▿, 2.5 to 3.5 mm zone; ▪, entire apex.
