Carnation (Dianthus caryophyllus L.) is an important flower crop, having substantial commercial value as a cut-flower due to the long vase-life and wide array of flower colors and forms. Standard carnation varieties perform well under cool climates but are very susceptible to high temperatures which adversely affect the yield and the quality of the cut-flowers. Despite several studies of carnat...

The main object of this study is to investigate the effect of plant growth regulators on the prolongation of vase life of two kinds of cut carnation under normal and ethylene. Carnation is one of the most popular flowers that has a short life due to its sensitivity to ethylene. Also, the effect of plant growth regulators on several physiological traits under ethylene stress and normal condition...

abstract the main goals of this study was to evaluate the effects of ethanol and essential oils of three medicinal plants namely thymus vulgaris, satureja hortensis and carum copticum on extending dianthus caryophyllus cut flower vase life. for this purpose three individual trials were conducted using a completely randomized design with three replications. in the first trial, effects of ethanol...

We investigated the effects of sucrose and nano-silver (NAg) on extending the vase life of cut carnation flowers "Edun". Sucrose (pulse treatment) suppressed ethylene production by downregulating the genes that code for its biosynthesis. Relative to the control, however, sucrose significantly promoted xylem blockage on cut stem surfaces and reduced relative fresh weight, antioxidant activity, a...

An experiment was conducted to quantify luminescence of white cut flower carnations after exposure blue glow-in-the-dark powder. Powder applied the flowers as either dip (3, 6, or 9 g) spray solutions in 240 mL water for 4 seconds plus a control. Stem fresh weight, relative stem diameter, and overall solution absorption were greatest on day 4. Only 6-g had greater average quality ratings than c...

The effect of leaf extracts of Psidium guajava and Piper betle on prolonging vase life of cut carnation flowers was studied. "Carola" and "Pallas Orange" carnation flowers, at bud stage, were pulsed 24 hours with a floral preservative. Then, flowers were placed in a vase solution containing sprite and a "germicide" (leaf extracts of P. guajava and P. betle, 8-HQC, or a copper coin). Flowers tre...

abstract reduction of post harvest losses in cut flowers and increasing their vase life, with consideration to high expenses of production is very necessary. one of the effective factors is presence of flowers near each other. this study was performed to investigate the interaction of some important cut flowers on their post harvest characteristics in vase solution (in combination or alone) in ...

Stem and leaf tissues of carnation (Dianthus caryophyllus) plants appear to contain a natural antisenescence factor since removal of most of these tissues from cut carnation flowers hastened their senescence. However, kinetin (5-10 mug/ml) significantly delayed senescence of flowers with stem and leaf tissues removed. In addition, the life span of cut flowers with intact (30-cm) stems was incre...

Ethylene is a plant hormone with endogenous production associated with the process of senescence for a number of cut flowers. Different stressogenic factors, including signals such as pollination, exogenous ethylene and auxins have been found to be associated with the increase in ethylene emission and a specific tissue response has been documented. The present study was undertaken with the aim ...
