| Research Abstract |
The release rates of 8 anti-cyanobacterial allelochemicals from Myriophyllum spicatum were determined. By adding the compounds to(i) a cyanobacterial medium where a cyanobacterium and green algae were inoculated or(ii) pond water including cyanobacterial on the basis of their release rates so as to simulate their excretion by M. spicatum, the cyanobacterial dominance was prevented, though the culture conditions are more preferable for the cyanobacterial growth.
