• The α-amylase induced by helminthosporol and gibberellic acid in the embryo-less endosperm of barley was separated into the three fractions, α_1,α_2 and α_3, by DEAE-cellulose column chromatography. A maximum amount of the α_2 was induced by gibberellic. acid and that of the α_3 by helminthosporol. After rechromatography, the α_2 induced by gibberellic acid and the α_3 induced by helminthosporol showed their respective single bands in an electrophoresis agar gel zvmogram. On the other hand, the α_1 induced by helminthosporol and gibberellic acid showed three bands. Dihydrohelminthosporic acid, a derivative of helminthosporol, induced the same isozymes as helminthosporol did.
