Research Abstract |
The invasive aquatic weeds grow dense community and it is caused damage at the national life. Purposes of this research obtains the information for control, and prevent damage more than now. The reproduction of H. umbellata and H. verticillata was equal the reproduction of specific invasive alien species "H. ranunculoides" under high nutrient concentration. However, creeping stems died under drying condition during a day on summer. The dormancy of H. ranunculoides seeds was different according to maturity."Lagarosiphon major" formed the dense community at the place where gradual flow and mud piled bottom.
