• The effect of PGE_1 and PGE_2. on the induction of acid phosphatase activity in embryoless barley half-seeds was examined. These compounds were found to promote the total amount of enzyme synthesized as well as the amount released into the medium to nearly the same levels obtainable when these seeds are incubated in GA_3 or cyclic AMP. The enzyme induction by PGE_1 and PGE_2 was inhibited by cycloheximide, ABA, 6-methyl purine and acetylsalicyclic acid, but not by AMO-1618. A time course for the induction of acid phosphatase activity by PGE_1 and PGE_2 lagged behind by 9 hr a similar time course obtained when seeds were incubated in GA_3 or cyclic AMP. Some of the implications of these results are discussed.
