芸苔素甾醇类物质（Ｂｒａｓｓｉｎｏｓｔｅｒｏｉｄｓ，简称ＢＲｓ）是广泛存在于植物界的一类新的植物生长物质。ＢＲｓ表现的调节植物生长的生理活性及作用机理与其它的植物激素不同。这类新型的植物生长物质已被广泛应用于农业生产。本文综述了国内外多年来有关ＢＲｓ的生理功能、构效关系及合成等方面的研究进展。
Brassinosteroids (Brassinosteroids, referred to as BRs) is a new class of plant growth substances widely found in the plant kingdom. The physiological activities and mechanisms by which BRs regulate plant growth are different from those of other plant hormones. This new type of plant growth material has been widely used in agricultural production. This review summarizes the research progress on physiological functions, structure-activity relationship and synthesis of BRs at home and abroad over the years.
