Abstract

Laboratory experiments showed that the submersed macrophyte Myriophyllum verticillatum L. released oxygen to, and substantially increased redox potential of, reduced solutions bathing the roots. This oxidation was light-dependent, and proceeded at rates similar to those reported for other submersed plants, but lower than those reported for bog and emergent plants. During 72-day laboratory incubations, chemical oxidant demand of sediment pore waters increased slowly in the presence of M. verticillatum. However, the plants had no significant effect on sediment organic content. The results provided no evidence that oxidation by roots of M. verticillatum can counter accretion of organic sediment.
