Dry weight of rice organs. Dry weight of panicles, non-flag leaves, flag leaves, stems/sheaths and roots collected during grain filling (GF) and full maturity (FM) stages of rice plants supplied with 5, 20 or 200 μM of Fe(III)-HEDTA from panicle exertion (PE) onwards. Values are the averages of at least three samples ± SE. Different letters indicate that the means (between different Fe supplies) are different by the Tukey HSD test (P ≤ 0.05). Error bars may be too small to be visible in the figure.
