Outline of Final Research Achievements

Zostera japonica have an important role around the coastal inner sea area, and make a dense population named Zostera bed. In this study I intend to conduct a restoration methods of Zostera bed with reference to characteristics of seed germination and rhizome growth. For restoration of the bed it was more effective to utilize fast rhizome growth than seed germination. So, cultivation studies in laboratory were designed under controlling water temperature and day length, accumulation and consumption of photosynthetic products in the rhizome were estimated by HPLC with reference to reproduction strategies. Transplantation of Z. japonica was also performed in the natural sea area. Then, effective restoration method of Z. japonica were developed in this studies.
