Summary of P-values from analysis of variance for measurements of fine-root stress (POX, LOD) and leaf and stem characteristics between control and waterlogged individuals for all species. Numbers in bold are significant at P < 0.05. Samples for POX and LOD were collected immediately after waterlogging, while numbers associated with assimilation and stomatal conductance signify measurements taken immediately after waterlogging (e.g., Assimilation-1 and Conductance-1) and following a 10-day recovery period (e.g., Assimilation-10 and Conductance-10). POX (peroxidase activity); LOD (lipid oxidative damage).
