结合过去的工作基础,对2008年5月底以来黄海西部沿海水域漂浮聚集的绿藻样品进行了分类学研究。经鉴定,其为绿藻门石莼目石莼科浒苔属的浒苔Enteromorpha prolifera,其主要分类鉴定特征为藻体暗绿色或亮绿色、管状扁压、中空、主枝明显、分枝较多、密集且细长。文中对其生境习性及其分布特征也作了较详细地介绍。
Taxonomical studies on green alga Enteromorpha prolifera were carried out. The algae formed a large scale of floating swarm along near-shore area of western Yellow Sea recently in summer 2008, causing a heavy burden of cleanup for the sailing competition of the 29th Olympic Games held in Qingdao City. This species is characterized mainly by thallus, 1--2m high and 1--2cm thick, dark or light green, tubular compressed, hollow frond, distinct main branch, dense and slender long branches, irregularly arranged, polygonal or sub--cycloid cells, 7--20μm long and 7--15μm wide at upper part, 7.5--18μm long and 7.5--15μm wide at middle part, and 8--17μm long and 8--15 μm wide at lower part of thalli, square or rectangle cells leaning to a side on transverse section with 10--15μm and 10--15 μm, 10--12μm and 10--16 μm, 15--30 μm and 10--15 μm respectively, cell with one pyrenoid, sometimes 2--5. Its habit, distribution, and reproduction were also presented in details.
