武汉地区硅质磷片金藻的初步研究

1986年11月,在武汉植物所的3个池塘及东湖附近的池塘内采集的标本中,含有大量的具硅质磷片的金藻,共11种,分别隶属于Spiniferomonas,Paraphysomonas, Chrysosphaevella, Mallomonas和Synura 5个属。本文提供了这些藻的硅质磷片、刺及毛的电镜照片。这些藻在中国研究得很少,许多种都是第一次报道,它们中的大多数在世界上其它一些地区也是普遍出现的,有些则毫无疑问地属于世界性分布。

SILICA-SCALED CHRYSOPHYTES OF WUHAN,A PRELIMINARY NOTE

Samples from three ponds in Wuhan Botanical Garden and from a pond near Wuhan Eastern Lake, obtained in November 1986, contained a rather rich flora of silica-scaled chrysophytes, altogether 11 species of the genera Spiniferomonas, Paraphysomonas, Chrysosphaerella, Mallomonas and Synura. They have been listed in Table 1, and electron micrographs of their silica scales, spines and bristles have been given in Plate Ⅰ. These algae have hardly been investigated previously in China, and all the species found at Wuhan are new to the country. Most of them are otherwise common in parts of the world, some of them must certainly be considered cosmopolitan.
