Gibberellic acid-induced synthesis and release of alpha-amylase in barley aleurone tissue was inhibited by abscisic acid. This inhibition was relieved by simultaneous application of ethylene ranging in concentration from 0.1 to 100 microliters per liter. When CO(2) was applied, it eliminated the effect of 0.1 microliter per liter ethylene and reimposed the abscisic acid inhibition. All concentrations of CO(2) tested from 400 to 10(5) microliters per liter counteracted the effect of 0.1 microliter per liter ethylene, but had no observable effect on any higher concentration of ethylene. The results indicate that some processes necessary for embryo growth may be subject to regulation by ethylene and carbon dioxide at naturally occurring concentrations of the gases.
赤霉素诱导的大麦糊粉层组织中α-淀粉酶的合成和释放被脱落酸抑制。这种抑制作用可以通过同时施用浓度为 0.1 至 100 微升/升的乙烯来缓解。当应用二氧化碳时，它消除了 0.1 微升/升乙烯的作用，并重新施加了脱落酸的抑制作用。测试了从 400 到 10(5)微升/升的所有浓度的二氧化碳都抵消了 0.1 微升/升乙烯的作用，但对任何更高浓度的乙烯都没有明显影响。结果表明，胚胎生长所需的某些过程可能受到乙烯和二氧化碳在气体自然浓度下的调节。
