“…Normally, hybrids with higher ethylene production (DDG) have shorter vase life than hybrids with lower ethylene production (MCJ) and vice versa. This observation is in conformity with the results of Wu et al (1991) and Onozaki et al (2001) on carnation, which reported that various cultivars displayed different vase lives and those cultivars with low ethylene production, had a longer vase life. Pretreatment with 1-MCP also prolonged vase life of the cut orchid flowers by about three days compared with control (Table 1).…”

“…The DDG produced much more ethylene compared to MCJ (Table 1). Flowers of various taxa (Woltering & Van Doorn, 1988) and even different cultivars of same species (Mayak & Tirosh, 1993;Wu et al, 1991) produced different rates of ethylene. So, it could be suggested that the behaviour of the orchid hybrids toward treatments also depended on their genetic capabilities.…”

Orchids possess a very special place amongst ornamental plants. But high ethylene sensitivity and early flower senescence of orchid result in a short vase life and rapid quality deterioration which is of great concern for the growers, traders and consumers. An attempt was made to study the influence of 1-methylcyclopropene (1-MCP) (0 and 300 nL L ) in prolonging vase life and maintaining quality of two cut orchid hybrids Dendrobium 'Darren Glory' (DDG) and Mokara "Calypso Jumbo" (MCJ). Results showed that orchid hybrids exhibited differences in their ethylene sensitivity, vase life, 1-aminocyclopropane-1-carboxylic acid (ACC) content and ACC oxidase activities. Pre-treatment with 1-MCP resulted in reduced ethylene production, vase life, ACC content and ACC oxidase activities, but increased bud opening %. Pre-treatment with аquеous ozone failed to influence all those parameters except bud opening %. Interaction effects of hybrid and 1-MCP were significant for ethylene production, hybrid and ozone for vas life, 1-MCP and ozone for bud opening %, and hybrid, 1-MCP and ozone for ethylene production and vase life. Aqueous ozone markedly contributed to the inhibition of microbial growth in vase solution. Pre-treatment of the cut orchid flowers with 300 nL L -1 1-MCP, followed by using 5.2 mg L -1 aqueous ozone as the vase solution could be recommended to maintain quality and extend vase life of both the DDG and MCJ orchid hybrids.

“…Although there is variation in the ethylene production characteristics of carnation cultivars (Wu et al 1991), the ethylene-climacteric nature is most clearly seen in the cultivar 'Crowley Pink' (Downs & Lovell 1986). In such cultivars, ethylene production increases during senescence, and the ethylene accelerates the rate of senescence.…”

Sugar and protein levels and rates of respiration and ethylene production were measured for Geraldton waxflower (Chamelaucium uncinatum) flowers in order to characterise flower development and senescence in this cut flower crop. Ten sequential stages of floral development were identified. Sugar levels increased during bud development, the highest concentrations (c. 130 mg sucrose equivalents/g dry weight (DW) being measured during the nectiferous stages of flower opening. There was little variation in either soluble or insoluble protein levels during flower development, levels averaging around 19 and 25 mg bovine serum albumin (BSA) equivalents/g DW, respectively. In flowers cut and maintained individually, sugar and protein levels decreased rapidly after harvest, suggesting their use as respiratory substrates. Sprig senescence was characterised by loss in fresh weight and decreasing Received 23 November 1995; accepted 13 February 1996 water use. In flowers taken from sprigs in vases, sugar and protein levels increased slightly (Day 4) before decreasing with senescence (Day 8). Flowers on sprigs appeared to deteriorate at c. 8 days after harvest, in concert with the decreasing sugar and protein levels. Respiration rates were initially high (1432 ml/kg per h) for the flowers from harvested sprigs, and declined during vase life. Ethylene production also decreased during vase life from an initial level of 1.32 μJ/kg per h. The absence of respiratory and ethylene production peaks indicates that Geraldton waxflower flowers are nonclimacteric in nature. H95065

“…Since the early 1990s, several commercial carnation cultivars ('Sandra', 'Chinera', 'Killer', 'Epomeo', 'Sandrosa', 'Roland', 'White Candle', etc.) with extended vase life have been reported 4,19,20,25,30,37,40,41 ( Table 1). These cultivars have a much longer vase life than most commercially grown standard carnations with climacteric ethylene production (e.g.…”

The vase life of cut flowers, or flower longevity, is one of the most important characteristics that determine their quality and their ability to satisfy consumer preferences. To improve the vase life of carnations, conventional cross-breeding techniques were used to develop many carnation lines with a long vase life. Two new cultivars, 'Miracle Rouge' and 'Miracle Symphony', with a genetically determined long vase life, were developed. They had vase lives of 17.7 to 20.7 days (3.2 to 3.6 times the vase length of the 'White Sim' cultivar) under standard conditions (23ºC, 12-h photoperiod, 70% RH). The ethylene biosynthesis pathway in these cultivars was almost completely blocked during natural senescence, which was responsible for the long vase life. Changes in ethylene sensitivity with flower senescence were evaluated using a time-lapse video recording system, which provides a simple and accurate way of evaluating ethylene sensitivity. The video system revealed that the ethylene sensitivity of various cultivars including 'Miracle Rouge' and 'Miracle Symphony' after anthesis decreased with increasing age.Disciplines: Horticulture / Plant breeding Additional key words: ethylene production, ethylene sensitivity, flower longevity, flower senescence JARQ 42 (3), 137 -144 (2008)
