Recovery ability in relation to carbohydrate content of Potamogeton maackianus growing in two dissolved oxygen concentrations (8 and 2 mg L-1) was investigated during 28 days exposure to very low irradiance (about 0.06 μmol m-2 s-1). Plant weight remained relatively constant (0.19 g dry wt plant-1) within the initial 21 days in the high oxygen treatment, but decreased to 0.14 g dry wt plant-1 at the end of the experiment. In low oxygen environments, plant weight was similar within the initial 14 days, but decreased to 0.08 g dry wt plant-1 at ...
