Summary
The oxygen consumption of four aquatic plants has been determined at various concentrations of dissolved oxygen and at three different temperatures.
Oxygen consumption rates (mg oxygen/g dry weight per hr) at 20°C in air-saturated water were Berula erecta, 1.25; Callitriche obtusangula, 2.8; Hippuris vulgaris, 1.96; and Ranunculus pseudofluitans, 1.90.
Oxygen consumption rates increased with increase in dissolved-oxygen concentration within the experimental limits of 1.2–17 p.p.m. dissolved oxygen. The relation of oxygen consumption to this range of oxygen concentrations can be described by the empirical equation R = aC b. Increase of temperature has been shown to increase the rates of oxygen consumption. Q10 values ranging from 1.32 to 3.48 have been obtained.
