Effect of flooding on total chlorophyll (a), total soluble sugar (b), and protein (c) in the leaf tissues of D. antarctica. Graphs show changes (in percent) 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 and 0.05 levels of confidence
