Interrelationship of several phytohormones in the regulation of rose petal senescence


, : Interrelationship of several phytohormones in the regulation of rose petal senescence. Acta Horticulturae (41): 103-116

Petal senescence was studied in cut flowers of the cvs Dr. Verhage (short-lived) and Lovita (long-lasting). At least 3 phytohormones, viz. cytokinins, ethylene and abscisic acid (ABA), controlled senescence. The endogenous level of cytokinins declined with age, being lower in Dr. Verhage than in Lovita. Ethylene evolution rose in the initial stage of senescence, being higher in Dr. Verhage.

The 5 external petals of cut flowers (Rosa hybrida, cultivars Sweet Promise and Royalty) were discarded and measurements were made on the following 5 petals.

In previous work, senescence of rose petal cells was shown to be accompanied by a gradual decrease of membrane fluidity. Concomitantly, an increase in the free sterol-to-phospholipid ratio was found. Both observations were verified in this study....

Accumulated experimental evidence suggests that the decline in the content of membrane components such as phospholipids (PL), is a key event in flower senescence. This loss of membrane integrity can be modulated by ethylene. The aim of this work w...

Comparative studies were made of ABA and cytokinin levels and of ethylene production by rose petals of the short- and long-lived cvs Golden Wave (syn. Dr. Verhage) and Lovita, respectively. In both cvs the ABA level increased as the flowers aged;...

A rise in ethylene evolution followed by an increase in ABA level were observed during rose petal senescence. External application of ethylene accelerated senescence and induced a rise in endogenous ABA-like activity. The application of ABA promot...
