Abstract: Carnation (Dianthus caryophyllus L.) flowers were subjected to low oxygen to investigate the physiological effects on flower senescence. The effect of ultra low oxygen (0.6-0.8%) led to low accumulation of ethanol that amounted to 8 mg/l in the tissue pulp in 19 days. The content of acetaldehyde showed an exponential decrease in its previous value after a subsequent exposition of cut carnations to air but still at a cold storage temperature. The content of sugars such as sucrose, glucose and fructose linearly decreased with small differences between ULO and RA conditions. The sucrose content was at a trace concentration. Visual symptoms of injury were observed in ULO conditions after 19 days of storage when brown spots appeared at the top of petals.
