Alcohols and Carnation Senescence

  title={Alcohols and Carnation Senescence},
  author={Meng-Jen Wu and Lorenzo Zacar{\'i}as and Mikal E. Saltveit and Michael S. Reid},
Continuous treatment with 8% ethanol doubled the vase life of 'White Sim' carnation (Dianthus caryophyllus L.) flowers. Other alcohols, other concentrations of ethanol, or pulse treatments with up to 8% ethanol had little or no effect. Butanol and longer-chain alcohols shortened vase life and caused the flower stem to fold. During their eventual senescence, the petals of ethanol-treat ed flowers did not inroll; instead, individual petals dried slowly from their tips. Very little ethylene was… Expand

Effect of ethanol on ethylene biosynthesis and sensitivity in cut carnation flowers
Abstract The vase life of cut carnation ( Dianthus caryophyllus cv. Barbara) flowers was significantly extended by continuous treatment with 1% (v/v) ethanol. To investigate effects of ethanol onExpand
The use of acetaldehyde to control carnation flower longevity
The potential use of acetaldehyde as a post-harvest treatment is however impractical, due to the inefficiency of pulse treatments and ineffectiveness in preventing the action of exogenous ethylene. Expand
Responses of cut carnations to a low oxygen level in the ambient atmosphere
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 lowExpand
Influence of ethanol on climacteric senescence in five cultivars of carnation
Abstract The effects of ethanol on carnation (Di‐anthus caryophyllus L.) cut flowers were studied by treating five cultivars ('Yellow Candy’, ‘Sandrosa’, ‘Francisco’, ‘White Candy’, and ‘Iury') withExpand
Physiological response and extension of vase life of cut carnation flowers treated with ethanol and acetaldehyde. II. Protein content and enzyme activity
Ethanol and acetaldehyde both prevent the formation of ethylene bysenescing cut carnation flowers. This is due to the almost complete inhibitionof the activity of 1-aminocyclopropane-carboxylic acidExpand
The role of ethanol or acetaldehyde in the biosynthesis of ethylene in carnation (Dianthus caryophyllus L.) cv. Yellow Candy
Abstract Carnation ( Dianthus caryophyllus L.) cv. Yellow Candy flowers were treated with ethanol solution (4%) in the absence or presence of 1 or 10 mM l -methionine, or ethanol or acetaldehydeExpand
Ethanol reduces sensitivity to ethylene and delays petal senescence in cut Tweedia caerulea flowers
Tweedia caerulea flowers are sensitive to ethylene and the closing of the flowers, a characteristic of senescence, is accelerated by exposure to ethylene. T. caerulea flowers were continuouslyExpand
Effect of butanol, propanol and pentanol on the quality of cut Carnation cv. 'Nelson'
Carnation (Dianthus caryophyllus L.) is one of the most popular cut flowers in the world with the most economical importance to flower industry. This plant is categorized among cut flowers and isExpand
Is Acetaldehyde the Causal Agent in the Retardation of Carnation Flower Senescence by Ethanol
Summary A 3 % ethanol holding solution inhibits the conversion of 1-aminocyclopropane-l-carboxylic acid (ACC) to ethylene, and doubles the vase-life of cut carnation flowers. Although the mostExpand
Post harvest behavior and the effect of ethanol, methanol, and sucrose on the vase life of Matricaria parthenium cut flowers were studied. For this purpose, flower scapes were treated with differentExpand


Influence of ethanol on ethylene biosynthesis and flower senescence of cut carnation
Ethanol was the most effective alcohol in delaying carnation flower senescence of the tested series methanol, ethanol, propanol, tert- butanol and n-butanol. Expand
Effect of alcohols and their interaction with ethylene on the ripening of epidermal pericarp discs of tomato fruit.
The similar inhibitory effects of methanol, ethanol, and n-propanol at concentrations which did not stimulate ion leakage, and the relationship between activity and lipophilia of the alcohols suggest that their mode of action was through disruption of membranes associated with ethylene action.

Effect of endogenously synthesized and exogenously applied ethanol on tomato fruit ripening.
Tomato (Lycopersicon esculentum Mill. var Castlemart) fruit ripening was inhibited by tissue concentrations of ethanol that were produced by either exposure to exogenous ethanol vapors or synthesisExpand
The influence of aliphatic alcohols on leaf senescence.
The effects are compared with reported effects on seed germination, on hemolysis and animal membranes, and especially on permeability to K(+) ions, and a tentative basis for the mechanism of action is advanced. Expand
