| 摘要: |
| 利用冷冻切片技术,通过形态学和解剖学方法,对采自我国东海沿岸浙江南麂岛的大型海洋红藻珊瑚藻目(Corallinales)的有节类群进行了分类学研究。经鉴定,共发现珊瑚藻目有节类群2属5种,分别为珊瑚藻科 Corallinaceae、叉节藻亚科Amphiroideae、叉节藻属Amphiroa、带形叉节藻A. beauvoisii；珊瑚藻亚科Corallinoideae、珊瑚藻属Corallina的鳞形珊瑚藻C. confusa、粗枝珊瑚藻C. crassisimaS、珊瑚藻C. officinalis和小珊瑚藻C. pilulifera。通过较为清晰的解剖学特征图片,对该5种有节珊瑚藻外部形态和内部特征进行了详细的比较与描述。结合近年来国际上有关上述部分物种的分类地位变化,对我国现存的带形叉节藻A. zanata、粗扁节藻BossiellaScretacea和大边孢藻 Marginisporum crassissimum的归并问题展开了详细分析与讨论,以期促进对珊瑚藻目海藻分类学有更加深入的理解。 |

| Abstract: |
| Based on the morphological and anatomical methods, and tissue cryomicrotomy, the taxonomical study on the geniculate coralline algae (Corallinales, Rhodophyta) collected from Nanji Island, Zhejiang Province were carried out. A total of 5 species including in 2 genera were identified. Among them, there are one species (Amphiroa beauvoisii) belonging to Family Amphiroideae and other (Corallina confusa, C. crassisima, C. officinalis and C. pilulifera) to Family Corallinaceae. Their morphology and inner anatomical characteristics were compared and described according to the pictures from frozen slices. Combined with recent international changes about the above species, the current problems referring to the species status of A. zanata, Bossiella cretacea and Marginisporum crassissimum recorded previous from Chinese coasts were analyzed and discussed in details. It will be advantaged in a more in-depth understanding to the coralline algal taxonomy. |
