(A) POD activity, (B) the ratio of POD activity,(C) DAB straining, (D) NBT straining to analyze the accumulation of O2− and H2O2 in wild type and transgenic ‘Dajiao’ (RNAi-22 and RNAi-15) before and after cold treatment. Data represent the means ± SE of at least three replicates. Letters indicate significant differences from 0 h cold treatment according to the Student–Newman–Keuls test (P < 0.05) (RE means recovery for 2 days)
