Abstract

Brassinolide (1) is a plant growth promoter that was first isolated in 1979 by workers at the US Department of Agriculture. 1 It exhibits activity at the nanogram/individual plant level and is thus active at concentrations several orders of magnitude lower than other known classes of plant growth promoters. Brassinolide and related brassinosteroids have attracted considerable attention because of reports that they significantly increase the yields of ...
