摘要
生物化感作用研究是近年来兴起的交叉学科,是化学生态学研究的重要领域。研究水域浮游植物化感作用对了解浮游植物之间、浮游植物与其他生物之间的相互作用及作用机理具有重要意义,对了解赤潮和水华的发生机制及其生态控制等具有非常重要的作用。综述了海洋和湖泊浮游植物化感作用和化感物质的内涵,讨论了水体浮游植物化感作用的特点、研究化感作用的基本方法、化感物质的种类以及影响化感物质作用的生物和非生物因素,详细介绍了浮游植物化感物质的作用机理以及逃避和拮抗化感作用的方式,同时对目前研究的热点问题及未来研究的方向做了简要概述。
Allelopathy may be one of factors contributing to the formation and/or maintenance of harmful algal blooms （HABs）, which are a serious ecological and socioeconomic problem facing the planet today. Because phytoplankton allelochemicals have the potential to deal with HABs, more attention are paid to the alleolpathy in phytoplankton. Progress and achievements are geting in this field and more and more allelochemicals are successfully purified and identified in cyanobacteria, dinoflagellate, green alga and diatoms. Most studies have observed and described the phenomenon of the allelopathy, but further detailed studies on the mode of action of allelochemicals are limited. The allelochemicals are capable of interrupting or stimulating many essential functions of prokaryotic and eukaryotic cells, cause the death of other algae, bacteria, viruses, and fungi. The allelochemical producer thereby have an adaptive advantage over other species. Authors focus on allelopathic interactions in marine and freshwater phytoplankton. Discussf the characteristics of allelopathy in phytoplankton, the basic approaches on allelopathy research, the chemical properties of allelochemicals and the factors affecting their production, particularly discuss the mode of action of allelochemicals and the defence mechanism to resist allelochemicals.
