24-Epibrassinolide is a type of brassinosteroid, a natural occurring plant hormone.[1][2] It was first discovered 1979 as a growth promoting substance in rape pollen,[3] and was subsequently discovered in many other plant organs.[4] 24-Epibrassinolide is essential for proper plant development growth and development,[5][6][7][8] is involved in the regulation of cell elongation and division,[9] and has been shown to improve plant functions in salt- and nickel-stressed environments,[10] as well as increasing enzyme activity.[11] It is sold commercially as a white powder for use in plant culture.
