摘要： For the last 2 years, vast accumulations of the unattached filamentous green alga, Enteromorpha prolifera, have occurred during summer along the coastal region of the Yellow Sea, China. However, algae do not seem to occur after the end of the fertile season. It has been suggested that banks of microscopic forms of the algae, primarily spores, function as a survival mechanism for this opportunistic alga. Therefore, in this study, field surveys and laboratory cultures were conducted to determine if somatic cells were serving as a propagule bank to enable the algae to survive through periods of unfavorable conditions. Laboratory experiments demonstrated that somatic regeneration was one of the most important approaches by which E. prolifera colonized and flourished in the study area. Indeed, at least 19.32% of somatic cells from the filamentous segments could survive for 2 months under various temperatures (0, 5, 10, 15, 20, and 30pC at an irradiance of 60pemol photons mpo sp#) and irradiances (darkness, 5 10, 15, 20 and 30pemol photons mpo sp# at a temperature of 20pC). Additionally, greater than 35.85% of the somatic cells could survive at 0pC or in darkness for 2 months, and no less than 15.99% of these cells resumed growth when the temperature and irradiance were adjusted to the normal levels (20pC and 60pemol photons mpo sp#). Furthermore, the results of field surveys revealed that viable E. prolifera was widespread in high quantities in the sediment of the Yellow Sea when the macroalga was absent. Taken together, the results of this study suggest that somatic cells may act as an overwintering stage for the annual spring bloom of E. prolifera. These findings should be useful in future studies conducted to behavior of somatic cells in green tide as well as in the management of future spring blooms of E. prolifera.
