陆生植物化感抑制铜绿微囊藻作用效应及机制研究进展

抑制藻类繁殖,控制水华爆发,是对富营养化水体完成生态修复过程中面临的首要挑战,如何高效安全的抑藻是亟待解决的问题.利用植物化感作用控制富营养化水体中有害藻类大量繁殖是有效的手段之一,但是利用陆生植物化感物质进行抑藻的研究较少.本文从草本植物(菊科/罂粟科、百合科、禾本科)、木本植物以及中草药类植物三大类详细介绍了陆生植物对水华爆发中的主要藻类铜绿微囊藻的抑制效应,并且针对化感物质的分离鉴定和物质基础、作用机制等进行阐述,最后对利用陆生植物化感物质开发抑藻剂的研究思路和注意问题提出了建议.

Research advance in allelopathy effect and mechanism of terrestrial plants in inhibition of Microcystis aeruginosa.

The inhibition of algae reproduction and control of harmful algal bloom are the primary challenges in the ecological restoration of eutrophicated water. It is urgent to inhibit algae over-reproduction in green and effective ways, one of which is the use of plant allelopathic effect. How-ever, few study focused on allelochemicals of terrestrial plants. Here, we introduced inhibition of Microcystis aeruginosa over-reproduction by allelochemicals from three categories of terrestrial plants, including herbaceous plants (Compositae/Papaveraceae, Liliaceae, Graminaceae), woody plants, and Chinese medicine plants. The classification, separation and identification of alleloche-micals from terrestrial plants that could be used for the inhibition of M. aeruginosa were summarized. Finally, the allelopathic mechanism to inhibit M. aeruginosa was discussed in detail to support the development of algistat. We also proposed some suggestions for the further development of algistat.
