Fig. 1From: The aluminum distribution and translocation in two citrus species differing in aluminum toleranceThe effects of Al toxicity on Al distribution in lateral roots A, primary roots B, leaves C and stems D of C. sinensis and C. grandis seedlings. Seedlings of C. sinensis and C. grandis were treated with nutrient solution (Control, pH 4.3) or supplemented by 1.0 mM Al3+ (1.0 mM Al toxicity, pH 4.3) for 21 days. The values represent mean ± SE (N = 5). Significant differences (p ≤ 0.05) between treatments are indicated by different lettersBack to article page
