蓝藻

The advantage and limitation of using DGGE in uncovering genetic diversity and the potential role of endophtic bacteria in phylogeny and synchronic evolution among the Azolla, cyanobacteria and bacteria were discussed.

文中也讨论了应用DGGE研究遗传多样性的优点、不足以及内生细菌在满江红－蓝藻共生体的系统发育和协同进化中的可能作用。

Azolla,a symbiosis of blue green alga and aquatic fern,widely distributesin rice paddy fields,lakes and swamps.

萍是固氮蓝藻与蕨类植物的共生体，广泛分布于稻田、湖泊及沼泽等水生生态系统。

In this study, differences among tolerant capabilities of three species of nitrogen-fixation cyanobacteria (Anabaena azollae, Anabaena flos-aquae, Anabaena azotic) to two new sulfonylurea (Monosulfuron and Monosulfuron ester) were studied, which could be used to further explain the resistant mechanism to sulfonylurea herbicides and how these herbicides take effect.

本文以满江红鱼腥藻、固氮鱼腥藻及水华鱼腥藻为代表，利用环境毒理学的研究手段，通过研究3种固氮蓝藻对2种磺酰脲类除草剂---单嘧磺隆、单嘧磺酯的耐药性差异来揭示对磺酰脲类除草剂产生抗药性和耐药性的机理。

Results 18 microalgae species were detected from the 42 samples including 4 species in Cyanophyta, 9 in chlorophyta, 4 in bacillariophyta and 1 in Euglenophyta.

结果 共发现18种微藻，包括4种蓝藻、9种绿藻、4种硅藻、1种裸藻。

Of the total 262 species found in this area, 82 occurred in spring, 117 in summer, 119 in autumn, and 141 in winter. Taxonomically, 252 species in 67 genera were Bacillariophyta, 8 species 5 genera were Pyrrophyta and 2 species 1 genus were Cyanophyta.

中文摘要：2006 年8 月—2007 年4 月对广东省徐闻珊瑚礁区的浮游植物进行了周年的季节调查，结果共检出浮游植物262 种：春季82 种、夏季117 种、秋季119 种、冬季141 种，其中硅藻门67 属252 种，甲藻门5 属8种，蓝藻门1 属2 种。

Results show that there are 73 species,62 genus,8 phylum phytoplankton,which is mainly composed of the Chlorophyta ,Bacillariophyta and Cyanophyta.

2005年12月和2006年6月对苏州平原河网区57个浅水湖泊的浮游植物群落进行了调查，共检出浮游植物8门62属73种，浮游植物主要由绿藻、硅藻和蓝藻组成。

Compared to CK, the rice-fish ecological system increased its density and biomass, decreased the predominance of Bacillariophyta and Cyanophyta, and increased the diversity index.

稻鱼共作显著增加稻田水体浮游植物的密度和生物量，降低硅藻和蓝藻的优势度，增加绿藻和裸藻的优势度，提高了稻田水体浮游植物多样性指数。

The results showed that the freshwater species were predominant, and 45 species of algal (5 phylums, 32 genera), in which 18 species of Bacillariophyta belong to 12 genera, 15 species of Chlorophyta one genus, 10 species of Cyanophyta 7 genera, and one specie of Euglenphyta and Chrysophyta; 37 species of zooplankton, in which 9 species of Protozoa, 14 species of Rotifera,...

结果表明，淡水种类占绝对优势，藻类5门32属45种，其中硅藻12属18种，绿藻1属15种，蓝藻7属10种，裸藻、金藻各1属1种；浮游动物共计37种，其中原生动物9种，轮虫14种，枝角类2种，桡足类8种，浮游幼虫及其它4种；底栖动物20种，分别为环节动物的多毛类7种，寡毛类2种，软体动物8种，甲壳动物2种，鱼类1种。

During the study period, the total of the phytoplankton species discovered was seven phylum,58 category and 183 kinds. Most of them belong to Cyanophyta, Bacillariophyta and Chlorophyta.

浮游植物种类组成显示，整个研究期间共发现7门58属183种，与蓝藻门、硅藻门和绿藻门为主。

Totally, 93 taxon belonging to 4 phyla were observed, among them, 68 taxon in 35 genera belonged to Bacillariophyta, 21 taxon in 11 genera for Dinophyta, 2 taxon in 1 genus for Cyanophyta and 2 taxon in 1 genus for Chrysophyta.

共鉴定浮游植物93种，其中硅藻35属68种，甲藻11属21种，蓝藻1属2种以及金藻1属2种。
