| 摘 要： | 设计一系列试验研究了四种沉水植物(金鱼藻、微齿眼子菜、苦草、伊乐藻)对铜绿微囊藻的抑制作用．单独培养试验结果显示金鱼藻和微齿眼子菜具有较强的抑制藻类生长的作用,连续滴加种植水试验显示抑藻作用进一步加强．在植物的生长过程中其化感物质是连续释放的．并考察N、P等营养因素及微生物干扰对抑藻实验的影响．

| Abstract: | Allelopathic inhibition activities of four submerged macrophytes (Potamogeton maackianus, Vallisneria spiralis, Elodea nuttalli & Ceratophyllum demersum) on Microcystis aeruginosa are investigated by a series of experiments in a short-term bioassay. Individual algal test reveals culture solution of P. maackianus and C. demersum have better effects on algal growth inhibition. Furthermore, continuous addition assays show strong growth inhibition by culture solution. Inhibitory activity is different in aquatic extracts from different section of P. maackianus. Removing the disturbance of microorganism by autoclaving influences algal assay. These results provide that unstable and excreting continuously allelopathic compounds by submerged macrophytes are the primary cause of algal growth inhibition. Interference with algal growth experiments was investigated in microorganism and nutrient elements of nitrogen and phosphorus. |
