2011年底紫菜栽培期对江苏如东海区条斑紫菜筏架Ulva L.属固着大型绿藻进行了样品采集与研究,分析了固着绿藻的形态学特征与分子生物学特征。根据形态学分析结果,所采集到的Ulva L.属绿藻样品主要包括Ulva prolifera,U.lin-za,U.compressa,U.flexuosa等4个种类,这与分子生物学的研究结果(主要包括LPP复合体、U.compressa,U.flexuosa等种类)基本一致。但具体的样品通过形态学分析与分子生物学的方法鉴定出来的结果具有差异;其中只有FJ04和FJ09,FJ05和FJ06,FJ07的形态学特征与分子生物学鉴定方法所得结果相同。根据本实验的研究结果,江苏省如东海区条斑紫菜栽培筏架上的大型固着绿藻至少包括U.prolifera,U.linza,U.compressa,U.flexuosa等4个种。部分筏架固着绿藻存在扭曲或皱褶等形态特征,但不具有大量的、复杂的分枝结构,也不具有相当数量的假分枝,与绿潮优势种存在较大的形态学差异。
At the end of 2011, during the cultivation of seaweed, samples were collected from Ulva L., a species of Porphyra subterranean raft, in the Rudong section of Jiangsu Province. Morphological and molecular biological characteristics of the immobilized green algae were analyzed. According to the results of morphological analysis, the collected samples of Ulva L. genus of green algae mainly include 4 species of Ulva prolifera, U.lin-za, U.compressa and U.flexuosa, which are in agreement with the findings of molecular biology Including LPP complex, U.compressa, U.flexuosa and other types) are basically the same. However, the specific samples were identified by morphological analysis and molecular biology methods. There were only morphological characteristics of FJ04, FJ09, FJ05, FJ06 and FJ07 which were the same as the results of molecular biological identification. According to the results of this experiment, the large-scale fixation green algae on the raft stand of Porphyra yezoensis in the Rudong area of Jiangsu Province at least include 4 species of U.prolifera, U.linza, U.compressa and U.flexuosa. There were some morphological features such as twisting or folds in some raft rafts, but they did not have a large number of complicated branch structures or a considerable number of false branches. There was a great morphological difference between the dominant species and the dominant species of green tide.
