摘要
Enteromorpha prolifera （Muell.） J. Agardh （Chlorophyta, Ulvophyceae）. which is distributed widely in the inter-tidal zone of the ocean, is one of the most common fouling green algae. However, the present understandings of the life history of E. profifera have been insufficient to explain their seasonal abundances. Thus it is essential to investigate how many reproductive strategies are likely to contribute to the successful colonization and flourishing of the green alga. In the present study the reproduction diversity of E. prolifera was observed and studied systematically by culturing chopped tissues. Our results showed that there are in total seven pathways of reproduction for E. prolifera including sexual, asexual and vegetative reproduction, it was indicated that the variety of the reproductive ways and the large quantity of reproductive cells produced and released during the reproductive season are the two key factors that facilitate colonization of E. prolifera. The reproduction of the alga E. prolifera mainly depends on asexual methods. The results presented here contribute to increasing our understanding about how the opportunistic macroalgae successfully maintain colonization and excessive growth.
