title: Effect of 2,5-Norbornadiene upon Ethylene Biosynthesis in Midclimacteric Carnation Flowers.
abstract: The climacteric increase in ethylene production in carnation (Dianthus caryophyllus L. cv White Sim) flowers is known to be accompanied by an increase in 1-aminocyclopropane-1-carboxylate (ACC) synthase and ethylene forming enzyme (EFE) activities. When midclimacteric flowers were exposed to 2,5-norbornadiene, which blocks ethylene action, ethylene production began to decrease after 2 to 3 hours. ACC synthase activity was markedly reduced after 4 hours and the increase in EFE activity was blocked indicating that the autocatalytic signal associated with ethylene action stimulates both enzyme activities.
