Effect of change in floral openness with floral age on floral display and reproduction in Gentiana

Acta Oecologica, 2015
Abstract Some plant species have flowers that open widely and then close slowly over time, resulting in changes in the width of the corolla opening. We examined the adaptive significance of retaining flowers with relatively closed corollas using Gentiana triflora var.

FACILITATION IN AN INSECT-POLLINATED HERB WITH A FLORAL DISPLAY DIMORPHISM

Ecology, 2006
Population context should influence pollination success and selection on floral display in animal-pollinated plants because attraction of pollinators depends not only on the characteristics of individual plants, but also on the attractiveness of co-occurring conspecifics.

Floral displays: genetic control of grass inflorescences

Current Opinion in Plant Biology, 2007
Inflorescences in angiosperms are complex structures that have many different types of meristems. Among complex inflorescences, the best studied are in the grass family. Multiple inflorescence genes have been cloned from grasses over the past few years, many of them by positional cloning using the rice genome as a source of positional information ...

Adaptive Design of the Floral Display in Asclepias syriaca L.

American Midland Naturalist, 1974
In the common milkweed, inflorescence size above a certain size is not correlated with seed set or pollination rates. The number of pods matured by each inflorescence is limited, and a minimum number of flowers appear to be necessary to ensure that pod production, within this limit, is maximized.

Floral display and breeding system of Jatropha curcas L.

Forestry Studies in China, 2007
Plant flowering and breeding characteristics are important for us to understand the reproduction of plant populations. In this paper, we studied the reproduction characteristics of Jatropha curcas in Yuanjiang County (23°36′N, 101°00′E), Yunnan Province. The plant produces flowers in dichasial inflorescences.

Effect of floral display on reproductive success in terrestrial orchids

Folia Geobotanica, 2006
Almost one-third of all species in the familyOrchidaceae offer no reward to insect pollinators. In the absence of a reward, floral display (number of flowers), may be the most important component of insect attraction but the role of floral display in capsule production of both deceptive (nectarless) and rewarding (nectariferous) orchids has not yet ...

Mating cost of large floral displays in hermaphrodite plants

Nature, 1995
HERMAPHRODITISM comprises outcrossing whenever the proximity of male and female organs allows self-fertilization1 and interference between sexual functions2. Many floral traits of animal-pollinated angiosperms encourage cross-fertilization3, as recognized by Darwin4-6; however, these characteristics may also allow pollination between flowers on the ...

IMPACT OF INSECT POLLINATOR GROUP AND FLORAL DISPLAY SIZE ON OUTCROSSING RATE

Evolution, 2006
Despite the strong influence of pollination ecology on the evolution of selfing, we have little information on how distinct groups of insect pollinators influence outcrossing rate. However, differences in behavior between pollinator groups could easily influence how each group affects outcrossing rate.

Genetic Correlations with Floral Display Lead to Sexual Dimorphism in the Cost of Reproduction

The American Naturalist, 2005
In dioecious plants, females typically invest more biomass in reproduction than males and consequently experience stronger life-history trade-offs. Sexual dimorphism in life history runs counter to this pattern in Silene latifolia: females acquire less carbon and invest more biomass in reproduction, but males pay a higher cost of reproduction.

The role of inner staminodes in the floral display of some relicMagnoliales

Plant Systematics and Evolution, 1984
The inner staminodes (between stamens and carpels) in some relicMagnoliales (Austrobaileyaceae, Degeneriaceae, Eupomatiaceae, andHimantandraceae) are not just reduced stamens; they are very elaborate organs. InEupomatiaceae, Himantandraceae, and probablyDegeneriaceae they have their own secretory structures which do not occur on the stamens. These play
