利用植物化感作用抑藻的研究进展

Advance Research on Allelopathy Effects of Plants for Inhibiting Harmful Algae

利用植物化感作用抑制藻类具有生态安全和灵敏高效等优点,对水体富营养化的生态控制具有极其重要的意义。本文研究了利用植物化感作用抑藻的进展,从化感物质对藻细胞光合作用、酶活性、细胞膜、细胞超微结构、基因表达的影响方面探究了植物化感抑藻作用的机理。并分别就水生植物和陆生植物中提取的各类化感抑藻物质的抑藻效果进行分析比较,尤其探讨了木本植物抑藻的潜在价值,为开发新的抑藻剂提供理论指导。本文还针对目前的研究现状,提出植物抑藻领域存在的问题及前景展望。

The use of plant allelopathy for inhibiting harmful algae,with the advantages of high efficiency and sensitivity to algae controlling and ecological security to aquatic organisms,will play a significant role on ecological control of water eutrophication. The advance research on allelopathy effects of plants for inhibiting harmful algae was introduced,in which the mechanisms of algal-inhibition were analyzed from aspects of photosynthesis,enzyme activities,cell mem brane,cell ultrastructure,gene expression. And the effect of allelochemical extracting from the aquatic plants and terrestrial plants on anti-algae was compared,especially the value of woody plants was explored,which would provide the theory guide for developing new algicide. The probroms of allelophathy of plants on algae were point out and the prospect of allelopathic algea control was put forward.
