Fig. 4 in Effect of ozone treatment on glutathione (GSH) status in selected berry fruit

Fig. 4. The effect of ozone treatment on the antiradical activity (A) and H2O2 level (B) in selected berries. Mean values (n = 18) with standard deviation (error bars) with *, **, *** are statistically different from the respective control at p <0.05, p <0.01, and p <0.001, respectively (one-way ANOVA, Tukey test). Mean values with the same lower (control fruit) or upper (ozonated fruit) case are not statistically significant according to the t-Tukey test (p> 0.05). On the figure: ns - not significant.
