| 摘 要： | 用比较解剖学方法观察提江沿海浒苔属（Enteromorpha ）海藻的形态结构，并结合统计分析对其进行 物种鉴定。结果表明，依据藻体分校的有元、数量及分校与主枝直径的大小等形态特征，鉴定的浒苔属j海藻有6种1个变型，分别为缘管浒苔（E. linza）、肠浒苔（ E. intestinalis ）、扁浒苔（ E. compressa ） ，浒苔（E. proliferα）、 条浒苔（E. clathratα）、由浒苔（ E·flexω5α）和肠浒苔宽叶变型（ E. intestinalis f.broadifolium） 0藻体长度由 大到小依次为浒苔、条浒苔、缘管浒苔、肠浒苔、扁浒苔和炀浒苔宽叶变型：细胞呈多角形，藻体的位置不同其细胞大小有所变化，除由浒苔和条浒苔外，其他4种1个变型浒苔的中部细胞最小;所有种类的细胞均有淀粉核，其中肠浒苔、缘管浒苔和扇浒苔仅1个淀粉核，而其他种出现多个淀粉核，尤其条浒苔和曲浒苔数量最多，可达6个以上。定量描述浒苔属6种1个变型的形态特征、内部结构，并发现浒苔属海藻非中空营状的结构特征。

| Abstract: | Eyeballing and microscopy observation on Enteromorpha spp. from the coastal area of Zhanjiang were carried out. Six species and one form, including E. linza, E. intestinalis, E. compressa, E. prolifera, E. clathrata, E. jlexuosa and E. intestinalis f broadifolium, were determined primarily by comparative anatomical method combining with statistical analyses.. These species were characterized by the morphology of branches （present or absent, more or less）, the differentiation of diameter sizes of thallus between main branches and lateral branches, the cellular sizes in different parts of the thallus, and the quantities of pyrenoid in cells. The length of six species decended as the following： E. prolifera, E. clathrata, E. linza, E. intestinalis, E. compressa and E. intestinalis f brordifolium. Cells of these Enteromorpha were polygonal, the size of cells varied in different parts of thallus, and the cells in middle part were smaller except for E. jlexuosa and E. clathrata. Pyrenoid was present in cells of all species, among which one pyrenoid is present in E. intestinalis, E. linza and E. compressa, more than two pyrenoids were observed in other species, and even more than six pyrenoids were found in E. clathrata and E. jlexuosa. The morphological and microstructural characters of these species were described quantitatively, and the identification key was generalized. |
