| 摘要: |
| [目的]研究鼠尾藻(Sargassum thunbergii)有性生殖相关因子间的关系,分析鼠尾藻群体的有性生殖能力。[方法]通过统计分析方法,研究藻体长度与侧枝数、侧枝长度与生殖托数、生殖托长度与生殖托挂卵数间的关系。[结果]藻体长度与侧枝数、侧枝长度与生殖托数、生殖托长度与生殖托挂卵数间都为线性正相关,利用回归方程推算,1株成熟的鼠尾藻藻体能产生2×105~3.3×106个受精卵。[结论]1株成熟鼠尾藻的产卵量基本可满足1 m2的采苗生产需要。 |

| Abstract: |
| [Objective] In order to assess the fertility of Sargassum thunbergii,the factors which related to sexual reproduction of S.thunbergii were analyzed.[Methods] According to the relationships between thallus length and lateral branch number,lateral branch length and receptacle number, and receptacle length and egg number,the regression analysis of related factors were conducted in sexual reproduction.[Results] Results showed that a mature thallus of S.thunbergii could produced 2×105~3.3×106individuals of eggs.[Conclusion] It indicated that a mature S.thunbergii thallus could produce sufficient eggs for 1 m2 collectors in seedling production. |
