摘　　要：植物化感物质由于对藻类抑制的高效性和选择作用性,以及对环境无污染等特点而备受关注,有望成为具有应用价值的安全性生物抑藻技术。文章探究了利用植物化感作用抑制有害藻类生长的进展,从藻细胞密度、叶绿素含量、超微结构及生长代谢、抗氧化酶活性等方面分析了化感抑藻作用效果的评价方法,重点阐述了陆生植物对水华藻、赤潮藻主要藻种的抑制作用,包括草本植物中一些农作物和药用植物以及木本植物中的常见树木,同时对这些陆生植物中所含抑藻物质开展了探索与分析,为开发新的抑藻制剂提供理论指导,深入讨论了陆生植物化感物质抑制丝状藻的潜在价值,实现了抑藻对象的多元化,提出了陆生植物化感抑藻研究中存在的主要问题,并对其应用前景进行展望。The inhibitory allelopathy of plants on algae aroused extensive concern because of its high efficiency and selective character of inhibitting harmful algae,as well as harmless to the environment.It is expected to be a valuable and safe alternative for algal bloom control with the intensive study.The progress of the inhibition on the harmful algae by allelopathy was introduced,the evaluation methodology of allelopathic effect were analyzed from aspects of algae cell density,chlorophyll content,growth and metabolism and ultrastructure,antioxidant enzyme activities.The inhibition of water boom algae and red tide algae by terrestrial plants were mainly described,Some herbaceous plants such as crops and medicinal herb as well as some ligneous plants such as common trees were included in these terrestrial plants.The antialgal compounds in these terrestrial plants were explored and analyzed,which provide theoretical guidence for developing new algistat.The potential value of inhibiting filamentous algae by allelochemicals was further discussed,which achieved diversity of algal-inhibiting objects.The problem of allelopathy by terrestrial plants were pionted out and the prospect of allelopathic algae control was put forward.
