<abstract xmlns="http://www.w3.org/1999/xhtml"> The present investigation was aimed to study changes in ethylene production, ACC content and antioxidant enzymes of cut spray carnation (Dianthus caryophyllus L.) flowers that had been treated with amino-oxyacetic acid (AOA), benzyladenine (BA) and 1-methylcyclopropene (1-MCP). Maximum vase life in ‘Optima’ spray carnations was obtained with 0.6 mg l-1 1-MCP. Ethylene production was significantly decreased by AOA at concentrations over 100 mg l-1, BA at 30 mg l-1, and 1-MCP at all concentrations, compared with the control. A significant increase in ACC content was observed in 1-MCP treated cut flowers compared with the control. However, the decline in ACC content was observed after using 100 or 150 mg l-1 AOA. A significant increase in SOD, CAT and POX enzyme activities was observed in the treatment with 0.6 mg l-1 1-MCP.</abstract>
