| 摘要: |
| 坛紫菜（Porphyra haitanensis）属暖温性海藻，是中国东南沿海的重要栽培物种，2011年度栽培面积达30余万亩。其生活史过程比较复杂，既有雌雄异体，也有雌雄同体；既存在无性生殖，也存在有性生殖；其能否产生单孢子也常常引起争议。为此，本文总结了坛紫菜的生殖及生活史的研究现状和存在的问题，旨在为坛紫菜的遗传育种提供一定的理论参考。 |

| Abstract: |
| Porphyra haitanensis, a warm-tempered seaweed, is an important cultivated species in the southeast coast of China. In 2011, P. haitanensis was cultivated in more than 300 000 mu. The life history of P. haitanensis is complex, involving both monoecism and dioecism, and the life cycle includes asexual and sexual reproduction. However, the production of monospores by P. haitanensis is disputed. Here, we aim to analyze and summarize the situation and problems pertaining to the reproduction and life history of P. haitanensis, and thereby provide a theoretical reference for breeding utilization. |
