The coevolution of flower longevity and self‐fertilization in hermaphroditic plants
Evolution; International Journal of Organic Evolution, 2021Self-fertilization, prevalent in plants, is typically divided into three modes - prior, competing, and delayed selfing - based on the timing in which it occurs. Flower longevity affects both the opportunity for pollination and the resources allocated for fertility, and thus may influence the selection on different modes of self-fertilization ...

Studies on flower longevity in Digitalis
Planta, 1979Flower lifespan was terminated by corolla abscission 5-6 days after stigma opening in the unpollinated flower. Increased pollen loads produced increased seed set and reduced flower longevity progressively to a minimum of one day after pollination with pure pollen.

Temperature‐driven flower longevity in a high‐alpine species of Oxalis influences reproductive assurance [PDF]
New Phytologist, 2013 How high-alpine plants confront stochastic conditions for animal pollination is a critical question. We investigated the effect of temperature on potential flower longevity (FL) measured in pollinator-excluded flowers and actual FL measured in pollinated

Increasing flower longevity in Alstroemeria
Postharvest Biology and Technology, 2003The vase-life of Alstroemeria (cv. Rebecca) flowers is terminated when the tepals abscise. Abscission was accelerated by both chloroethylphosphonic acid (CEPA) and 1-aminocyclopropane-1-carboxylic acid (ACC). Petals abscised 24 h earlier compared with controls, when isolated cymes were placed in 340 nM CEPA, and earlier still when higher concentrations

Studies on flower longevity in Digitalis
Planta, 1983The flowers of Digitalis purpurea respond to pollination by rapid corolla abscission without any loss of corolla turgor, nor any significant loss of corolla constituents, relative to the corollas of unpollinated flowers of a similar age. The corollas of unpollinated flowers too eventually abscise, 6 d after the stigma opens, however, they do so with ...

Plasticity of flower longevity in Corydalis ambigua
Ecological Research, 1998We investigated the longevity of individual flowers of Corydalis ambigua Cham. et . during different periods of pollinator activity and at different temperatures. To measure potential (unpollinated) flower longevity of C.

Heritability of cut-flower vase longevity in Gerbera
Euphytica, 1981Estimates of broad-sense heritability for cut-flower vase longevity were 36 and 46 percent for a sample of Gerbera clones. Estimates of narrow-sense heritability for vase longevity were 0, 24 and 38 percent over 3 generations of the Davis Population. Response to selection for this character in this population is expected to be slow.

PCR-BASED MARKERS AND CUT FLOWER LONGEVITY IN CARNATION
Acta Horticulturae, 2005In carnation, the identification of molecular markers linked to flower vase life character could be an important tool to improve the efficiency of breeding programs, considering that this is one of the most important traits selected by breeders. Longevity is probably a complex quantitative trait, involving several genes showing predominantly additive ...

Genetic analysis of cut flower longevity in Gerbera
Euphytica, 1985The vase life duration and stem stiffness of 12 parent clones and 77 progenies of Gerbera jamesonii were studied both in summer and in winter. In winter, vase life was shorter and the stems were weak. Few exceptions from this general pattern were detected.
