摘 要 ：除草剂安全剂是一种化学物质,它可以通过生理或生化的途径降低除草剂对作物的毒性,而不降低除草剂的功效。安全剂影响作物的吸收和传导,诱导作物体内P450酶活性、谷胱甘肽调控及其靶标酶ALS的活性。其生理和生化机制研究,不仅有助于安全剂的开发和优化,同时也是了解和运用除草剂活性和抗性机制的途径。该文综述了近年来国内外安全剂生理生化作用机制的研究进展,并探讨其研究方向。

Abstract:Safeners are chemical agents that reduce the phytotoxicity of herbicides to crops by physiology or biochemical, without reducing the effectiveness of herbicides. Safeners affect the absorption and transmission of crops, also induce the activity of P450-induced metabolism, glutathione and ALS in crops. Particular attention has been paid to defining the biochemical and physiological mechanisms on safener, not only to assist safener development and optimization, but also as a means of understanding and manipulating the mechanisms which contribute to herbicide selectivity and resistance. This paper reviews the progress of the researches in safener biochemical and physiological mechanisms and prospect the future research needs.
