摘要:
根据国内外挺水植物化感作用抑制藻类的研究,对菖蒲等15科20种挺水植物化感抑制水华鱼腥藻等18种水华藻类的作用予以评述;归纳了挺水植物化感作用在影响藻细胞亚显微结构、酶体系活性、呼吸作用、光合作用、细胞膜和细胞内小分子物质的含量等6方面的抑制藻类生长的机理;对移植栽种植物共培养、从植物中提取化感物质和直接施加化感物质等3种类型抑制藻类的应用方式进行概述;结合当前我国水华频发、抑藻和除藻任务繁重的现状,指出存在的主要问题并提出今后研究和应用化感作用抑制藻类的展望。

Mechanisms and applications of algal growth inhibition by plant allelopathy among aquatic emerged plants
Abstract:
Based on the existing reports of the anti-algal allelopathy study of aquatic emerged plants, the inhibition effects of 20 species in 15 families of aquatic emerged plants, including Acorus calamus, on the growth of 18 species of bloom-forming microalgae, including Anabaena flosaquae, are reviewed. The inhibitory mechanisms for allelopathy are clustered into 6 categories, which refer to modifying the submicroscopic structure, enzyme system, respiration, photosynthesis, cell membrane and intracellular micromolecule content, respectively. The application modes for anti-algal practice may be summarized as three types which are co-culture, allelochemical extraction and allelochemical direct exertion. Finally, combined with the frequent outbreak situation of harmful algal bloom in China and the urgent needs for effective bloom prevention approaches, the subsistent main problems in above areas are pointed out and the further study about emerged plant allelopathy and its application to algal bloom prevention are prospected.
