| 摘 要： | 文章报道了2005～2007年针对铜藻Sargassum horneri有性生殖规律所开展的研究结果,包括生殖托发生、卵的排放、受精卵的发育及其与环境因子的关系。选择了潮间带典型的生态环境定点观察有性繁殖的过程,提出“铜藻以有性生殖为主,残枝营养繁殖为辅,共同维系种群繁衍”的推论。进行了筏式栽培、人工采苗、育苗及附苗基质选择等试验,为未来铜藻工厂化育苗和开展潮下带铜藻种群的恢复提供了科学依据。 |

| Abstract: | A series of culture experiments of the subtidal brown alga Sargassum horneri was performed during 2005～2007,including development of receptacles,discharge of eggs,impact of environmental factors on the development of the zygotes.Artificial seedlings derived from zygotes were obtained from selected individuals sampled from wild populations at Nanji Island,Zhejiang Province,China.Different substrates were tested for settlement of zygotes.Field in situ observation of the growth and reproduction of selected individuals was performed.Based on these results,we concluded that field population of this alga sustains itself principally through sexual reproduction.These results lay the basis of artificial seedling reproduction of this alga. |
