Effect of flooding on phenolic content (a) and CAT activity (b) in the leaf tissues of D. antarctica. Graphs show changes (in percent) in five parameters over a period of 7 days flooding (7d_F) and 2 days drainage (2d_D) when compared to the control (before flooding (BF)). Significant differences were calculated between control and flooding conditions with the paired Mann-Whitney U test; “•,” “*,” and “**”, respectively, indicate significance at the 0.1, 0.05, and 0.01 levels of confidence
