| Abstract: | Yellow prisms of asparagusic acid, with a molecular formulaof C4H6O2S2 were isolated from etiolated asparagus tissues (Asparagusofficinalis L.). This acid inhibits growth in lettuce and otherseedlings when applied in concentrations of 6.67x10–7Mto 6.67xl0–7M. The extent of activity was very similarto that of abscisic acid.
