Abstract

The induction of α-amylase by exogenously supplied gibberellin A1 (GA1) and GA4 in embryoless caryopses of Hordeum vulgare (cv. Himalaya) was determined indirectly by measuring reducing sugars released from the endosperm. The presence of the inhibitors of GA biosynthesis, 2-isopropyl-4-dimethylamino-5-methylphenyl-1-piperidinecarboxylate methyl chloride (Amo 1618), Ancymidol, 2-chloroethyl trimethyl ammonium chloride (CCC) or (R,S)-1-(4-chlorophenyl)-4,4-dimethyl-2-(1,2,3-triazolyl)pentan-3-ol (PP333) did not inhibit α-amylase production by either GA1 or GA4.
