Investigation on the chemical ecology characteristics of submerged macrophytes to establish the vegetation for improvement of water quality

测定了桃金娘中8种抗蓝藻化感物质的释放率。通过在(I)接种蓝藻和绿藻的蓝藻培养基或(Ii)包括蓝藻的池塘水中根据蓝藻的释放速率来模拟蓝藻的排泄，虽然培养条件更有利于蓝藻的生长，但阻止了蓝藻的优势。

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.
