Influence of duration of waterlogging and nitrogen application on the production of malonaldehyde (MDA) of rape leaves and roots under pot and field experiments. Capped bars above means represent ±SE of three replicates. Small alphabetical letters above mean denote the significant differences among treatment at P ≤ 0.05. The different application levels of nitrogen were N1 (0 kg ha−1), N2 (30 kg ha−1), N3 (60 kg ha−1) and N4 (90 kg ha−1). D0, refers to without waterlogging; D6, refers to waterlogging for 6 days and D9, refers to waterlogging for 9 days.
