摘 要: 鱼鳞藻属(Mallomonas)是金藻门植物中种类较丰富的属之一。该属植物表质上有规则地相叠成覆瓦状或螺旋状排列的硅质鳞片,鳞片及刺毛的形状和结构是该属重要的分类依据。为了解该属植物的形态结构,通过扫描电子显微镜(scanning electron microscope, SEM)观察,对采自山西省的6种鱼鳞藻属植物的超微结构进行初步研究,包括具尾鱼鳞藻(Mallomonas tonsurata)、条纹鱼鳞藻(Mallomonas striata)、网状鱼鳞藻(Mallomonas areolata)、光滑鱼鳞藻(Mallomonas caudata)、中肋鱼鳞藻(Mallomonas costata)和蛛形鱼鳞藻(Mallomonas acaroids),为我国淡水藻类植物资源与多样性的调查积累了资料,也为水质监测与评价中指示藻类植物的利用提供了依据。
关 键 词: 植物学;鱼鳞藻属;金藻门;超微结构;山西省
Title: Ultrastructure of six species in Mallomonas (Chrysophyta) from Shanxi province

Organization: College of Life Science, Shanxi University
Abstract: The genus Mallomonas belongs to Chrysophyta, which was reported as one of the largest genera in Chrysophyta. The algae of the genus has cells covered with silica scales arranging regularly as imbricate or armor shape, or freely. Some scales bear bristles and some do not. They are considered as the most important taxonomic characters for species determination and the taxonomy of the species. Based on the observation by scanning electron microscope (SEM), the ultrastructures of 6 species in Mallomonas (Chrysophyta) from Shanxi were studied, including Mallomonas caudata Ivanov em. Krieger, Mallomonas striata Asmund, Mallomonas areolata Nygaard, Mallomonas tonsurata Teiling em. Krieger, Mallomonas costata Dürrschmidt and Mallomonas acaroides Perty em Ivanov. The paper accumulates data for investigation of China fresh water phycophyta resources and their diversity, and provides basis for use of indicating phycophyta in water quality monitoring and evaluation.
