| Outline of Final Research Achievements |
Gametophyte of six industrial kelp species in Hokkaido were stocked under axenic condition. Zoospores were isolated from eight sporophytes, that were produced by selection or crossing, including individuals that cultured under high water temperature and low nutrient conditions, and the germinations were cultivated. Meanwhile, cellulose was picked as an epiphytic medium for seedling of kelp. In the inspersion experiment of seedling at the field, the growth of sporophytes that were thought to be germination of the seedlings was found after the half a year of execution. Furthermore, AgNa gel was picked as a supported substrate of bio-flavor extracted from kelp. It was confirmed that aroma substances work on attracting of sea urchin in the laboratory experiment. Because efficiency of the substrates containing the substances was confirmed for capture of sea urchin at the field, the application for cultivation of seedling is expected.
