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.
