| Abstract:
‘Sandra’ carnation flowers (Dianthus caryophyllus L.) lasted twice as long as flowers of ‘White Sim’. They showed neither the normal increase in ethylene production, nor a marked respiration climacteric during their eventual senescence. The EFE activity and ACC content of the flowers remained unchanged for 6 days in the vase. Exogenous application of ethylene did, however, induce sleepiness. The extended vase life of ‘Sandra’ carnations appears to be the result of repressed ethylene biosynthesis. | |
