AbstractThis study aimed to investigate the allelopathic activities between 3 Potamogeton spp. (Potamogeton maackianus, Potamogeton malaianus and Potamogeton pectinatus) and the toxic cyanobacteria (Microcystis aeruginosa). All Potamogeton spp inhibited the growth of M. aeruginosa in both coexistence and exudates experiments. Inhibition of M. aeruginosa growth by plant exudates depended strongly on the biomass of P malaianus. Initial pH (6.5-9.8) did not influence the inhibitory effects of P. malaianus exudates. However, the M. aeruginosa inhibited the net photosynthesis and respiration of all three pondweed test spp.. The decreases in photosynthesis and respiration were probably caused by the toxic compounds released by M. aeruginosa, rather than its shading effects. The M. aeruginosa also decreased the nutrients (phosphorus and nitrogen) uptake rates of macrophytes. The absorption rates of phosphorus and nitrogen and net photosynthesis were decreased sharply. These results will help to restore submerged plants in eutrophic waters.
