Fragrance volatiles of developing and senescing carnation flowers

Phytochemistry, 2001
Thirteen major volatiles of the carnation flower fragrance signature have been identified by GC/MS. Of these, ten, hexanal, (2E)-hexenal, 1-hexanol, 2-hexanol, 3-hexen-1-ol, nonanal, benzaldehyde, benzyl alcohol, benzyl benzoate and caryophyllene, were quantified.

Delay ofIrisflower senescence by cytokinins and jasmonates

Physiologia Plantarum, 2012
It is not known whether tepal senescence inIrisflowers is regulated by hormones. We applied hormones and hormone inhibitors to cut flowers and isolated tepals ofIris×hollandicacv. Blue Magic. Treatments with ethylene or ethylene antagonists indicated lack of ethylene involvement.

Ethylene in Flower Development and Senescence

2018
This chapter summarizes studies that have provided much insight into the role of ethylene in flower induction, flower development, and flower senescence. Ethylene-mediated induction of flowering is also utilized in the commercial production of mangos.

Ethylene and Flower Senescence

1984
The flower is a complex organ consisting of reproductive and vegetative tissues, each with differing rates of metabolism and senescence, which respond differently to exogenous ethylene. Furthermore, abscission layers may occur in some parts of the flower so that entire organs may abscind without obvious symptoms of the effects of ethylene on the ...

Molecular Genetics of Flower Senescence

2002
Senescence is the terminal phase in the development of a plant, plant organ or plant tissue. Flower senescence, for example, occurs after pollination when the petals no longer serve a useful purpose, and for certain flowers is accompanied by a climacteric rise in ethylene production.

Recent Topics on Flower Opening and Senescence in Cut Carnation Flowers

2020
This chapter describes recent topics on flower opening and senescence of carnation flowers, highlighting new chemicals found to promote flower opening in carnation flowers, and the allelic nature of two variants (DcACS1a and DcACS1b) of a senescence-related 1-aminocyclopropane-1-carboxylate (ACC) synthase gene (DcACS1). Xyloglucan oligosaccharides (XGO)

Ethylene Production During Senescence of Flowers

Journal of Horticultural Science, 1966
A method of determining ethylene production by detached flowers is described. A surge of ethylene has been shown to accompany the wilting of carnation flowers at the end of senescence. This surge is independent of fungal infection and it is concluded that in the infected flower the major source of ethylene production is the host tissues.A similar surge

Pollination-induced flower senescence: a review

Plant Growth Regulation, 1992
Ethylene has long been implicated in the control of the senescence of many cut flower species, but the control of senescence in relation to wild species has received much less attention. The longevity of individual flowers varies greatly from species to species; in some each flower is open for just a few hours, whilst in others the flower may persist ...

Abscisic acid and cut flower senescence

2006
The keeping quality of cut flowers, during the postharvest stages, is very important in the global market, where floricultural items must be extremely competitive. Postharvest physiological analyses of senescence point to plant hormones playing important roles in the promotion or inhibition of flower and leaf senescence.

Physiology and Molecular Biology of Flower Senescence

2016
Flower longevity is one of the most important traits of cut owers. An understanding of the postharvest biology of owers is needed to efciently develop postharvest technology. Ethylene is a key factor that regulates ower senescence in many plant species.
