Floral traits and their connection with pollinators and climate [PDF]
Annals of BotanyAbstract Background and Aims Floral characteristics vary significantly among plant species, and multiple underlying factors govern this diversity. Although it is widely known that spatial variation in pollinator groups can exert selection on floral traits, the relative contribution of pollinators and ...

Mycorrhizae influence plant vegetative and floral traits and intraspecific trait variation
American Journal of Botany, 2022AbstractPremiseArbuscular mycorrhizal fungi (AMF) can strongly influence host plant vegetative growth, but less is known about AMF effects on other plant traits, the relative impacts of AMF on vegetative growth versus floral traits, or AMF‐induced intraspecific variation in traits.MethodsIn an experimental greenhouse study, we inoculated seven species ...

Floral Trait Evolution of Angiosperms on Pacific Islands
The American Naturalist, 2020Animals frequently evolve unique suites of traits on islands, but whether plants evolve comparable island syndromes remains unresolved. Here, we test the prediction on the basis of natural history observations that insect-pollinated plants evolve smaller flowers on islands than on mainland communities.

Floral trait variation in fourCyclamen (Primulaceae) species
Plant Systematics and Evolution, 1998The purpose of this study is to examine floral trait variation between fourCyclamen species that show variation in their ability to reproduce in the absence of pollinators and in levels of inbreeding. Pollen and ovule production, pollen/ovule ratio, pollen volume, petal length and width, diameter of the corolla mouth, pistil and stamen length, and ...

Polymorphic Floral Traits in Linaria canadensis (Scrophulariaceae)
American Midland Naturalist, 1997-This study examined several aspects of a previously unreported flower color polymorphism in the annual plant Linaria canadensis. Natural populations in southeastern Georgia contained mainly two petal color morphs: the 'dark' purple morph and the 'light' blue morph (two individuals of a completely 'white' albino morph were also found). The frequency of

Science, 2002
FLORAL EVOLUTIONNew work is indicating that some pollinators might not deserve their starring evolutionary roles in shaping flower fashions. A growing number of scientists are looking for more subtle evolutionary forces--from nectar thieves and herbivores to environmental demands and developmental changes--that might also sculpt floral traits.

Floral traits and pollination ecology of European Arum hybrids
Oecologia, 2015Hybridisation is common in plants and can affect the genetic diversity and ecology of sympatric parental populations. Hybrids may resemble the parental species in their ecology, leading to competition and/or gene introgression; alternatively, they may diverge from the parental phenotypes, possibly leading to the colonisation of new ecological niches ...

QTL dissection of floral traits in Streptocarpus (Gesneriaceae)
Euphytica, 2020Flower shape and colour are key plant traits which are often strongly correlated with pollinator choice and reproductive isolation. To understand the genetic changes underlying variation in these traits, we performed the first QTL analyses of these traits in Streptocarpus (Gesneriaceae) using a segregating backcross (BC) population of (S.

Genetics of floral traits of Jaltomata procumbens (Solanaceae)
Brittonia, 2016Understanding the genetic control of key reproductive traits/characters facilitates better understanding of systematics and evolution. Accordingly, we employed hybridization studies to investigate the Mendelian genetics of eight floral traits of two divergent populations of Jaltomata procumbens, which appear to have undergone an evolutionary shift in ...
