Interactions between ethylene, CO/sub 2/, and ABA on GA/sub 3/-induced amylase synthesis in barley aleurone tissue. [Hordeum vulgare cv Himalaya]
Gibberellic acid-induced synthesis and release of ..cap 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/sub 2/ was applied, it eliminated the effect of 0.1 microliter per liter ethylene and reimposed the abscisic acid inhibition. All concentrations of CO/sub 2/ tested from 400 to 10/sup 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.
