项目摘要

It is generally believed that Japanese marine alga(seaweed) flora is extended their distribution from Vietnam, Kalimantan, Philippine and Taiwan to the islands of Japan. The survey of seaweeds in Philippines has been carried out on the coast of the main islands from 1987 to 1990. In 1993, the first survey was made on the coast of southern Vietnam during January, 17 and February, 14. The present survey has been carried out on coast of north and central Vietnam during February, 22 and March, 17 in 1994.From these surveys, more than 5000 sheets of collections of benthic marine algae (seaweeds) has been kept in the herbarium of Hokkaido University and Nha Trang institute of Materials Science, and the seaweed flora in Vietnam has been made in clear in this survey. Specially, Seaweeds of Porphyra, Grateloupiaceae, Gymnogongrus, Gracilaria, Laurencia, red algae and Sargassceae, Brown algae have been done the taxonomy and biosystematics by the members of this project. The new species of Sargassum have already reported by the materials of the first survey. Two species of Gracilaria have been cleared their life cycle in culture by the materials transplanted from Vietnam. From the living materials of Gymnogongrus and Grateloupia transplanted in Japan has gotten several new knowledge by culture. It was known that the agar qualities of Gracilaria fronds on the natural shores were better than the materials from many cultivated ponds. It needs that the new Graciralria strain is transplanted in the culture ponds. The good materials, kappaphycus alverazii of caraginan materials has transplanted from Japan to the vietnam by first survey. Their fronds are growing well in the ponds. They might become the new seaweed resources in Vietnam.Two members of Vietnam phycologists have done the joint work in the survey, and have visited in Kyoto University, Kyushu University and Kochi University in August of 1993.

一般认为，日本海藻区系的分布范围从越南、加里曼丹、菲律宾和台湾延伸到日本列岛。菲律宾海藻调查从1987年到1990年一直在主要岛屿海岸进行。1993年1月17日和2月14日在越南南部海岸进行了第一次调查。目前的调查是1994年2月22日和3月17日在越南北部和中部海岸进行了调查。通过这些调查，收集了5000多张底栖生物藏品。海藻（海藻）保存在北海道大学和芽庄材料科学研究所的植物标本室中，这次调查清楚了越南的海藻区系。特别是，本项目成员对紫菜、Grateloupiaceae、Gymnogongrus、Gracilaria、Laurencia、红藻和马尾藻科、褐藻等海藻进行了分类学和生物系统学研究。马尾藻新种已在第一次调查资料中报道过。通过从越南移植的材料，两种江蓠的培养生命周期已被清除。从移植到日本的Gymnogongrus和Grateloupia的活体材料中，通过培养获得了一些新的知识。据了解，天然海岸上的江蓠叶的琼脂品质优于许多人工池塘的材料。需要将新的江须草菌株移植到养殖池中。鹿茸胶原料的优良材料卡帕藻(Kappaphycus alverazii)经首次调查已从日本移植到越南。它们的叶子在池塘里生长得很好。它们有可能成为越南新的海藻资源。越南两名藻类学家共同进行了调查工作，并于1993年8月访问了京都大学、九州大学和高知大学。
