摘要: The morphological variability of the brown alga Undaria pinnatifida was studied in Peter Great Bay (Sea Japan). Comparison morphology algae growing at eight sites bay that have different water movement revealed three phenotypically population groups. A discriminant analysis a set traits demonstrated width undivided part lamina and stipe length make most significant contribution to discrimination detected Analysis environmental dependence showed depend generally on intensity, whereas thallus are influenced by light intensity surf degree.
