“…This suggests that these two cultivars are either low ethylene producers (Wu et al 1991), or are high in carbohydrate reserves (Ketsa 1989) or both. Treatment with ethanol at 4 or 6% gave maximum increase in vase life of responsive carnation flowers, except in 'Iury' where ethanol at 8% gave maximum increase in vase life.…”

“…Senescence of cut flowers is induced by several factors, e.g., water stress (Sankat & Mujaffar 1994), carbohydrate depletion (Ketsa 1989), micro-organisms (Witte & Van Doom 1991), and ethylene effects (Wu et al 1991). When ethylene is involved in carnation senescence, it is produced in a climacteric surge followed by in-rolling of petals termed climacteric senescence.…”

The effects of ethanol on carnation (Dianthus caryophyllus L.) cut flowers were studied by treating five cultivars ('Yellow Candy', 'Sandrosa', 'Francisco', 'White Candy', and 'Iury') with up to 8% ethanol solution and measuring vase life, solution uptake, delay in bud opening of flowers, and ethylene production. Treatment with 4 or 6% ethanol increased the vase life of 'Yellow Candy', 'White Candy', and 'Iury', but not of 'Sandrosa' or 'Francisco'. Cultivars showed variable response to ethanol treatment with regards to uptake of solution, vase life increment, and delay in bud opening. The highest increment in vase life after flower opening with 4% ethanol was for 'Yellow Candy', where the vase life doubled. Total ethylene production in untreated † Corresponding author. H98044 Received 22 September 1998; accepted 9 December 1998flowers varied according to cultivars; treatment with 4% ethanol inhibited ethylene production as well as sensitivity to ethylene. 'Yellow Candy' was the most sensitive to ethylene and most responsive to ethanol; 'Sandrosa' was the least sensitive to ethylene and least responsive to ethanol treatment. The effectiveness of ethanol in extending vase life correlated closely with the longevity, ethylene production, and ethylene sensitivity of each cultivar.

“…'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).…”

“…The 6 cultivars and 23 selected lines exhibited a wide range of variation in mean vase life (Tables 1 and 2 Ethylene sensitivity and ethylene production in the cultivars and selected lines The differences in ethylene sensitivity of the 6 cultivars and 23 lines on day 0 (Tables 1 and 2) revealed that 'White Sim', 'Nora', 'Excerea', 'Francesco', and 'Sandrosa' are highly sensitive with response times of 6.0 to 7.6 h. The response times of two selections 104-8 and 104-18 exceeded 10 h, whereas that of the remaining 21 lines ranged from 6.0 to 9.8 h. The 'Chinera', known for its low ethylene sensitivity (Wu et al, 1991), had the longest response time of 14.2 h.…”

Genetic improvement of flower vase life is an important breeding target. A breeding program aimed to improve the vase life of carnations (Dianthus caryophyllus L.) that carried out by repeatedly crossing and selecting promising progenies was effective. Thus, we developed many carnation lines with extremely long vase life by using the conventional cross-breeding technique. Selected lines from second-, third-and fourthgeneration have vase lives that are 2.7 to 4.1 times longer than the control cultivar, 'White Sim'. The mean vase life of line 108-44 was 23.6 days in 2003 and 19.1 days in 2004 (414% and 341% of 'White Sim' flower longevity, respectively). All selected lines showed low ethylene production in whole flowers during senescence. In addition, the petals and the gynoecia of three selected lines 908-46, 702-21, and 006-13, produced only trace amounts of ethylene during senescence, indicating that the ethylene biosynthesis pathway in these lines was almost completely blocked during senescence. Although ethylene sensitivity of the selected lines was generally high on day 0, immediately after harvesting, ethylene sensitivity after anthesis rapidly decreased with age in the three selected lines. These lines became completely ethylene-insensitive or showed low sensitivity at the end of senescence. Autocatalytic ethylene production by the gynoecia and petals of the three selected lines also decreased on days 3 and 6, respectively, after harvest.
