Senescence represents the last stage of floral development and is an active process that requires gene transcription and protein translation. A genetically controlled senescence program allows for the ordered degradation of organelles and macromolecules and the remobilization of essential nutrients from the petals.

Development and senescence of Grevillea'Sylvia' inflorescences, flowers and flower parts [PDF]
Plant Growth Regulation, 2004 To characterise the physiology of development and senescence for Grevillea 'Sylvia'. oral organs, respiration, ethylene production and ACC concentrations in harvested flowers and flower parts were measured. The respiration rate of harvested inflorescences decreased over time during senescence. In contrast, both ethylene production and ACC concentration

Daffodil flowers delay senescence in cut flowers
Phytochemistry, 2004Visible symptoms of tepal senescence in cut Iris x hollandica (cv. Blue Magic) flowers were delayed by placing one cut daffodil flower (Narcissus pseudonarcissus, cv. Carlton) in the same vase. Addition of mucilage, exuded by daffodil stems, to the vase water had the same effect as the flowering daffodil stem.

Ethylene and flower senescence
Plant Growth Regulation, 1992The end of the relatively short life of carnations held in air is associated with climacteric rises in ethylene production and respiration, and coordinate rises in activity of the enzymes of the ethylene biosynthetic pathway. Carnation sensescence is associated with derepression of specific genes, increased polyribosome activity, and major changes in ...

MECHANISM OF SENESCENCE IN CARNATION FLOWERS
Acta Horticulturae, 2005Senescence of carnation flowers is characterized by autocatalytic ethylene production from petals and subsequent wilting of the petals. Recent studies on the regulation of ethylene production and wilting in senescing carnation flowers revealed that (1) petal senescence is triggered by ethylene produced from the gynoecium during natural senescence, (2 ...

Current knowledge indicates that flower petal senescence is a form of programmed cell death called vacuolar cell death. In this process the cell first degrades most of the cytoplasm and organelles using an array of degradative enzymes present in the vacuole for reuse of the nutrients.
