The effect of H₂O₂ on seed germination and dormancy break in Arabidopsis. (a). Effect of different H₂O₂ concentrations on dormancy break of freshly harvested wild-type seed. Freshly harvested seeds were imbibed in water or different concentrations of H₂O₂ and the germination ratio was counted on the seventh day. (b) Effect of H₂O₂ and its production inhibitor DPI on freshly harvested seed dormancy and germination. (c) Effect of H₂O₂ and its production inhibitor DPI on non-dormant seed germination. Data represent the means±SE of four replicates, with 50 seeds each in a, b, and c. An ANOVA test followed by a rank test was performed. Different letters in (a) are used to indicate means that are significantly different (P <0.05).
