| 1 | Reproduction Diversity of Enteromorpha prolifera显示文摘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.prolifera 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. | Apeng Lin Songdong Shen Jianwei Wang Binlun Yan | 2008 | Journal of Integrative Plant Biology2008，50，5： | 46 |
| 2 | Comparison of Chlorophyll and Photosynthesis Parameters of Floating and Attached Ulva prolifera显示文摘In mid-May 2008 a serious green tide caused mainly by floating Ulva prolifera(Mller) J.Agardh(Chlorophyta,Ulvales) thalli struck the coastal area of Qingdao,China.To understand the present physiological conditions of the floating alga,in this work both laboratory and field investigations were conducted on the floating U.prolifera thalli in comparison with the attached U.prolifera thalli collected from the area.The floating thalli of three distinctively different colors and attached thalli at three different stages of sporangium formation process were characterized under a microscope,while their photosynthetic parameters were determined with chlorophyll fluorescence technology.On the other hand,the sporangium formation status of the floating U.prolifera thalli was surveyed both in the laboratory and in the field.Comparisons showed that both of the paired morphological characteristics and the paired physiological parameters of the floating and attached U.prolifera thalli were consistent.Furthermore,some spores were confirmed in the field and some motile particles were found within the floating thalli.These results suggest that the floating U.prolifera thalli with different colors could be at different stages of sporangium formation.However,our results also showed that the floating alga thalli have only a limited reproductive potential.This might limit the duration and the further geographic expansion of the green algal bloom. | Apeng Lin Songdong Shen Guangce Wang Qianqian Yi Hongjin Qiao Jianfeng Niu Guanghua Pan | 2011 | Journal of Integrative Plant Biology2011，53，1： | 20 |
| 3 | Study on the photosynthetic performances of Enteromorpha prolifera collected from the surface and bottom of the sea of Qingdao sea area显示文摘In this work, the photosynthetic performances of Enteromorpha prolifera thalli collected from the sur- face and bottom of the sea of Qingdao sea area were studied with chlorophyll fluorescence and oxy- graph technology. The samples with the highest photosynthetic activity among their kinds, the floating thalli from the sea surface of the south of the Qingdao Olympic Sailing Center and the sedimentary thalli from the mud surface of the bottom Tuandao bay, were chosen as representatives of surface thalli and bottom thalli, respectively. The results showed that the maximal PSII quantum yield of the floating thalli was significantly lower than the normal level although their photosynthetic activities were relatively high; the photosynthetic potential of the thalli form the mud surface was extremely low. Thus, it is indicated that the floating thalli are seriously stressed by their environment and the thalli from the mud surface are already dead or are dying. On the other hand, the results of the laboratory cultivation showed that the sedimentary thalli cannot regain normal photosynthetic activity even under normal illumination condi- tions. Thus, the thalli from the mud surface cannot become reproductive source of the alga even if they can reach sea surface again. Therefore, a preliminary conclusion can be reached that, up to mid-July 2008, the environmental conditions of the Qingdao sea area are not suitable for the growth of the alga E. prolifera and for this reason the biomass of E. prolifera, in the area, could be declining. | LIN APeng WANG Chao QIAO HongJin PAN GuangHua WANG GuangCe SONG LiYun WANG ZhiYuan SUN Song ZHOU BaiCheng | 2009 | Chinese Science Bulletin2009，54，3： | 14 |
