| 摘 要： | 对2012年12月至2013年4月黄海绿潮暴发前江苏紫菜养殖海域绿藻显微繁殖时空分布特征进行了研究。结果表明,在每月的调查中,调查海域绿藻显微繁殖体密度高值区均集中在如东近岸紫菜养殖海域。调查海域绿藻显微繁殖体数量在时间分布上呈逐渐升高的趋势。2012年12月至2013年4月调查海域平均绿藻显微繁殖体数量分别为56、71、471、550和1 049 ind/L。应用ITS序列与5S rDNA间隔序列分析并构建系统发育树发现,江苏紫菜养殖海域绿藻显微繁殖体种类组成为浒苔(Ulva prolifera)和曲浒苔(Ulva flexuosa)。通过对调查海域绿藻显微繁殖体种类构成比例分析发现,在绿潮暴发前2-4月,黄海绿潮优势种浒苔显微繁殖体成为江苏紫菜养殖海域的优势种。大量绿藻显微繁殖体可以在春末海区温度回升时期迅速萌发,因此推测江苏紫菜养殖海域存在的大量绿藻显微繁殖体为黄海绿潮的暴发提供了种子库。

| Abstract: | The distribution features of Ulva microscopic propagules in Jiangsu Porphya aquaculture regions from Dec. 2012 to Apr. 2013 were investigated. The result showed that in each month the high density zone of the Ulva microscopic propagules in investigated areas were widely distributed in Rudong inshore Porphyra acquaculture regions. In the investigated areas, the temporal distribution features of the number of Ulva microscopic propagules presented the trend of rising gradually. From Dec.2012 to Apr.2013 the average number of Ulva propagules in investigated areas was 56,71,471,550 and 1 049 ind/L. By using ITS sequence and 5S rDNA intervening sequence analysis and construction of phylogenetic tree, the molecular results showed that compositions of microscopic propagules were Ulva prolifera and Ulva flexuosa. By analyzing the species composition of Ulva microscopic propagules, we found that 2-4 months before the breakout of green tide Ulva microscopic propagules of the dominant species in the Yellow Sea green tide became the dominant species in Jiangsu Porphyra aquaculture regions. A large number of Ulva microscopic propagules could germinate rapidly with the rising of temperature at the late spring. Therefore we speculated that a large number of Ulva microscopic propagules that existed in Porphyra aquaculture regions in Jiangsu would provide seed bank for Yellow Sea green tides. |
