“…All evaluated cultivars in the present study were sensitive to exogenous ethylene, but large differences have been observed among them. The hypothesis that natural longevity was associated with low sensitivity to ethylene was not sustained (Müller et al, 1998). Long-life cultivars such as 'Baltico' and 'Pilar' were very sensitive to exogenous ethylene, and in contrast, short-life cultivars such as 'Exotica' and 'Mundo' were less sensitive to exogenous ethylene.…”

Vase life is one of the most important characters of postharvest cut flower quality. The onset of ethylene production and the amount of ethylene produced by flowers vary with the carnation cultivar, and thus influence their vase life. In the present study, differences in ethylene production and the response to exogenous ethylene among carnation cultivars were evaluated. Ten different cultivars: 'Baltico', 'Domingo', 'Exotica', 'Famosa', 'Kiro', 'Madame Augier', 'Master', 'Mundo', Pilar' and 'Reina' were studied. Five flowers for each cultivar were exposed for 8 hours to 1 µL L -1 exogenous ethylene concentration. Ethylene production, fresh weight and water uptake was measured daily throughout the experiments. The 10 different cultivars studied showed clear differences in vase life, ethylene production, onset time in ethylene production and response to exogenous ethylene. The shortest vase life was for 'Exotica' flowers which was only 11.6 days, while 'Baltico' and 'Pilar' lasted 2.5-3 times longer than 'Exotica'. Most of the investigated cultivars showed notable increases in the amount of ethylene. However, 'Baltico' and 'Pilar' flowers produced only a trace amount of ethylene and had the longest vase life. Results showed that cultivars with a long vase life ('Baltico' and 'Pilar') display high ethylene responsiveness and, in contrast, cultivars with a short vase life ('Exotica' and 'Mundo') present low responsiveness. The decline in fresh weight of cut flowers observed in the last phase of their vase life occurred earlier in short-lived cultivars than in the longer-lived ones.Additional key words: exposure to ethylene; fresh weight; petal in-rolling; water uptake and wilting.

“…'Dancing Queen'). This range of responses is similar to differences in the ethylene sensitivity of floral organs of Dianthus spp., Rosa hybrida and Kalanchloe blossfeldiana cultivars (Wu et al, 1991;Muller et al, 1998;Serek and Reid, 2000;Friedman et al, 2001). Previous investigations have established that treatments with 7 to 10 µl l -1 ethylene for 12 to 24 h at 20 °C are sufficient to induce flower abscission from several C. uncinatum cultivars including 'Purple Pride' and 'Alba' (Joyce, 1988(Joyce, , 1989Macnish et al, 2000a, b).…”

“…In numerous ornamental flowers such as roses, Begonia and Hibiscus, endogenous and exogenous ethylene are the causes of bud and flower abscission (Høyer 1984(Høyer , 1985Müller et al 1998;Woltering and van Doorn 1988).…”

Phalaenopsis frequently exhibits bud drop during production and in response to adverse postharvest conditions. The effect of exogenous ethylene on bud drop of mini Phalaenopsis was studied and ethylene sensitivity of four cultivars was compared. Water content, membrane permeability and ABA (abscisic acid) content in floral buds and flowers were determined after ethylene treatment. Exogenous ethylene induced flower bud drop in all testedPhalaenopsis cultivars and the different cultivars showed distinct differences in ethylene sensitivity. The cultivar Sogo 'Vivien' exhibited the highest bud drop, water loss and change in membrane permeability in floral petals, while Sogo 'Berry' showed the lowest sensitivity. The ethylene inhibitor 1-MCP (1-methylcyclopropene) reduced ethylene-induced floral bud drop in the cultivar Sogo 'Yenlin'. ABA content in floral buds was increased in response to ethylene and 1-MCP pretreatment inhibited the ethylene-induced increase in ABA levels efficiently. This finding suggests that the observed increase in ABA content during bud drop was mediated by ethylene. The interaction between ABA and ethylene is discussed.
