【摘要】 为了避免压载水作为媒介转移外来物种并造成污染危害,利用分子生物学技术研究宁波港来自印度洋、新加坡和美洲的压载水浮游植物。结果显示,新加坡和美洲的压载水没有检测到浮游植物。而印度洋的压载水里面含有硅藻门的直链藻属(Aulacoseirasp.)、海链藻属(Thalassiosirasp.)、骨条藻属(Skeletonemasp.)、冠盘藻属(Stephanodiscussp.)和星盘藻属(Discostellasp.);隐藻门的全沟藻属(Teleaulaxsp.)和斜片藻(Plagioselmissp.);绿藻门的括小球藻属(Chlorellasp.)、卵囊藻属(Oocystissp.)和Pseudococcomyxasp.;链形植物门包括新月藻属(Closteriumsp.)。同宁波港的港池浮游植物相比,生长速度快、抗逆性强的硅藻数量明鲜增多,有些种类是外来的。更多还原

【Abstract】 In order to avoid ballast water transfering alien organismsand contaminate environment as a medium,this paper studied the phytoplanktons in ballast water,which were collected in the port of Ningbo,from the Indian Ocean,Singapore and the American with the molecular biology technology.The results showed that phytoplanktons were not detected in the ballast water from Singapore and America.While,in the ballast water from Indian Ocean,there are Aulacoseira,Thalassiosira,Skeletonema,Stephanodiscus and Discostella,which belong to Bacillariophyta.Teleaulax and Plagioselmis,which belong to Cryptophyta.We also detected Chlorell,Oocysti,Pseudococcomyxa and Closterium,which belong to Chlorophyta and Streptophyta.Compared with phytoplankton in the Ningbo Port basin,the quantity of diatoms that have fast growth and strong resistance has increased.We found among these diatoms some types are external.更多还原
