摘要: 对植物化感物质抑藻机理,即化感物质影响藻细胞的光合作用、破坏细胞膜、改变细胞酶活性、影响细胞超微结构及基因表达等几个方面进行了综合评述。研究表明,化感物质主要通过降低叶绿素a含量,破坏光合系统Ⅱ,使细胞膜结构裂解,酶活性改变,抗氧化系统破坏,细胞膜内超微结构受损,基因表达异常等几个方面来抑制藻细胞的分裂或直接杀死藻细胞,从而减少藻细胞数量,抑制藻类的生长。未来应该从更微观角度,即基因表达、分子和遗传机制等方面对化感抑藻机理进行深入研究,以期为开发安全、高效的抑藻化感物质提供理论基础。

Abstract: This paper summarized the research progress on the action mechanisms of allelopathy in inhibiting algae, i.e., affecting the photosynthesis of algal cell, destroying algal cell membrane, changing the antioxidant enzyme activities in algal cells, and affecting algal cell ultrastructure and gene expression, etc. Mainly through reducing chlorophyll a content, destroying photosystem II and cell ultrastructure, making cell membrane structure lysis and gene expression abnormal, changing enzyme activities, and damaging antioxidant system, allelochemicals can reduce the number of algal cells and inhibit the growth of algae. The prospective research issues in this field were also proposed, with the focus on gene expression and molecular and genetic mechanisms, aimed to provide theoretical bases for developing safe and efficient allelochemicals in algal inhibition.
