摘要
山东近海近年来连续遭遇绿潮危害,绿潮种类组成是否发生变化?尚未有研究加以解决。2010年—2011年,对山东近海海域漂浮藻进行了调查和取样,选取采集的29株漂浮石莼属样品和2株固着石莼属样品,进行了形态学观察,并对其核糖体ITS、叶绿体rbcL基因和5S rDNA间隔序列进行了分子系统发育分析。结果表明,山东近海石莼属绿潮由浒苔U.prolifera、孔石莼U.pertusa和扁浒苔U.compressa共同构成,浒苔是优势绿潮藻种群,其次为孔石莼,扁浒苔发生很少。
In recent years,large-scale green tides formed by unattached filamentous alga,Ulva sp.,have repeatedly occurred in Shandong coasts of China.Has the composition of the green tide species changed？ So far,no studies have been tried to answer this question.Correct identification of the bloom species is required to understand and manage the blooms.In this study,the taxonomic status of 31 selected specimens from the Shandong coasts was assessed by using both morphological and molecular（ITS and rbcL sequences） data.In addition,5S rDNA analyses were performed for those samples clustering in the LPP clade.Three free-floating Ulva species were distinguished and described as U.prolifera,U.pertusa and U.compressa.The U.prolifera is the dominant green tide algae species,followed by U.pertusa,and U.compressa occurres rarely.
