Flower Position and Clonal Integration Drive Intra-Individual Floral Trait Variation in Water-Hyacinth (Eichhornia crassipes, Pontederiaceae)

open access: yesBiology
Intra-individual variation in floral traits is linked to plant fitness, playing a central role in sexual selection. This variation can arise from architectural constraints, such as flower position on the inflorescence axis, and from environmental factors.

Evolutionary processes from the perspective of flowering time diversity. [PDF]

open access: yes, 2020
Although it is well appreciated that genetic studies of flowering time regulation have led to fundamental advances in the fields of molecular and developmental biology, the ways in which genetic studies of flowering time diversity have enriched the field

Gladiolus cut flower postharvest performance to direct breeding efforts

open access: yesTechnology in Horticulture, 2023
Gladiolus is an important floricultural and nursery crop used for gardening and floral design. The lengthy, linear stems with large, brightly colored flowers make it a long-term favorite of floral designers.

Multifunctional Bracts in the Dove Tree Davidia involucrata (Nyssaceae:Cornales) [PDF]

open access: yes, 2008
Although there has been much experimental work on floral traits that are under selection from mutualists and antagonists, selection by abiotic environmental factors on flowers has been largely ignored.

Spatial Relation of Bumblebees (Hymenoptera-Apidae) with Host-Plant and their Conservation Issues: An Outlook from Urban Ecosystem of Kathmandu Valley, Nepal [PDF]

open access: yes, 2019
Ecology and conservation status of bumblebee species remains poorly understood, especially in rapidly degrading urban ecosystems, which is important considering the role of bumblebees in the pollinations. We collected more than 200 bumblebee (Bombus

Phylogeny and floral trait evolution in Jaborosa (Solanaceae)

open access: yesTAXON, 2015
AbstractThe genus Jaborosa (Solanaceae), which comprises 22 species endemic to southern South America, encompasses remarkable flower variation. To test if this interspecific variation is related to transitions in pollination mode and to major concomitant geological changes, phylogenetic relationships within the genus were reconstructed.

Climate-Related Floral and Vegetative Size Variation in Leptosiphon androsaceus (Polemoniaceae) [PDF]

open access: yes, 2012
Phenotypic plasticity in plants is a vital adaptive response to changing environmental conditions. Floral and vegetative morphology often varies as biotic and abiotic factors vary.

B-Function Expression in the Flower Center Underlies the Homeotic Phenotype of Lacandonia schismatica (Triuridaceae) [PDF]

open access: yes, 2010
Spontaneous homeotic transformations have been described in natural populations of both plants and animals, but little is known about the molecular-genetic mechanisms underlying these processes in plants.

Floral traits affecting fire blight infection and management [PDF]

open access: yesTrees, 2011
Erwinia amylovora, the causative agent of fire blight, colonizes primarily the flowers of the sub-family Maloideae. Commercially important fruit tree species such as apple (Malus domestica) and pear (Pyrus communis) are also affected by the disease. Epiphytic bacterial populations develop on the stigma, from where the pathogen colonizes the hypanthium,
