Gibberellic acid-induced alpha-amylase synthesis in barley (Hordeum vulgare L.) aleurone layers was inhibited by abscisic acid, and the inhibition was partly removed by additional gibberellic acid alone and by ethylene alone. Together additional gibberellic acid and ethylene almost eliminated abscisic acid inhibition of amylase synthesis. Time course studies of these phenomena showed that the effect of abscisic acid, ethylene, and varying concentrations of gibberellic acid on the course of amylase synthesis were either to speed up or slow down the whole process and not to affect the lag phase or the linear phase separately. The data are discussed in relation to previous studies of abscisic acid-gibberellic acid interaction.
脱落酸抑制大麦糊粉层中赤霉素诱导的α-淀粉酶合成，单独的赤霉素和乙烯部分解除这种抑制。单独的赤霉素和乙烯一起几乎消除了脱落酸对淀粉酶合成的抑制作用。对这些现象的时程研究表明，脱落酸、乙烯和不同浓度赤霉素对淀粉酶合成过程的影响要么加速整个过程，要么减缓整个过程，而不会分别影响迟滞期或线性期。这些数据与之前关于脱落酸-赤霉素相互作用的研究进行了讨论。
