| 摘 要： | 以温州市洞头区人工养殖羊栖菜和野生羊栖菜为研究样本,详细描述了羊栖菜成熟孢子体有性生殖,假根与侧生枝无性生殖的繁殖生物学特征和生活史流程。详细记录了羊栖菜卵、精子和受精卵的减数分裂和有丝分裂过程,假根、茎(主茎和侧生茎)、叶(气囊)和生殖托(雌托和雄托)等4类器官生长、发育和分化过程,胚、幼孢子体和成熟孢子体形态结构特征。在此基础上对现有羊栖菜繁殖生物学特征及生活史流程进行了补充和修正,增加了羊栖菜侧生枝无性生殖和羊栖菜幼孢子体期有性生殖的相关内容,并重新绘制了羊栖菜生活史流程图。该研究结果将为开展羊栖菜养殖生态学研究,深层次解析羊栖菜生殖节律、种群繁衍与环境关系奠定基础。

| Abstract: | In this research, the biological characteristics and life cycle of Sargassum fusiformis, including the sexual reproduction of its mature sporophytes, asexual reproductions of its rhizoids and lateral branches were comprehensively studied. The meiosis and mitosis of the eggs, sperm and fertilized eggs of maricultural and natural S. fusiformis in Dongtou coastal waters were recorded in detail. In addition, the growth, development and differentiation of organs such as rhizoids, stems (main stem and lateral stem), leaves (air-bladders) and receptacles (female and male), as well as the morphology and structure features of embryos, young and mature sporophytes of S. fusiformis were described. On this basis, the existing reproductive biology and life cycle of S. fusiformis were partially supplemented and revised. The contents about asexual reproduction of S. fusiforme lateral branches and sexual reproduction of young S. fusiforme sporophytes were supplemented, and the life cycle diagrams of sexual and asexual reproduction of S. fusiforme were redrawn. The results of this study laid a foundation for the study of the maricultural ecology and the reproductive rhythm of S. fusiformis, as well as the population reproduction and its relationship to environmental factors. |
