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，日本海藻区系是从越南、加里曼丹、菲律宾和台湾延伸到日本岛屿的。1987年至1990年在菲律宾主要岛屿海岸进行了海藻调查。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。本调查于1994年2月22日和3月17日在越南北部和中部海岸进行。通过这些调查，在北海道大学植物标本馆和芽庄材料科学研究所保存了5000多张底栖藻类（海藻）标本，并在本次调查中明确了越南的海藻区系。本项目成员对紫菜科、苔藻科、金盆草科、葛盆草科、月桂草科、红藻、马尾藻科、褐藻等海藻进行了分类和生物系统学研究。马尾藻新种已在第一次调查资料中得到报道。用越南移栽的材料，清除了两种江蓠的培养生活圈。从移植到日本的裸子属和藤属植物的生活资料中，通过培养获得了一些新的认识。已知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。需要在培养池中移植新的格拉氏菌菌株。经首次调查，从日本移植到越南的卡拉胶材料是优良的材料——鹿角胶材料。它们的叶子在池塘里长得很好。它们可能成为越南新的海藻资源。越南心理学家的两名成员在调查中共同完成了工作，并于1993年8月访问了京都大学、九州大学和高知大学。
