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.
用外源赤霉素 A1（GA1）和 GA4 诱导大麦（ cv. Himalaya）无胚乳子粒中α-淀粉酶的产生，是通过测量从胚乳中释放的还原糖来间接确定的。GA 生物合成抑制剂 2-异丙基-4-二甲基氨基-5-甲基苯基-1-哌啶羧酸甲酯盐酸盐（Amo 1618）、安可密多、2-氯乙基三甲基氯化铵（CCC）或（R，S）-1-（4-氯苯基）-4,4-二甲基-2-（1,2,3-三唑基）戊烷-3-醇（PP333）的存在并不抑制 GA1 或 GA4 对α-淀粉酶的产生。
