Does the Floral Nectary in Dracocephalum moldavica L. Produce Nectar and Essential Oil? Structure and Histochemistry of the Nectary [PDF]

open access: yesBiology, 2022
Dracocephalum moldavica is an aromatic plant with a lemon scent and versatile use. Its flowers produce large amounts of nectar, which is collected by bees and bumblebees. The aim of the study was to investigate the structure of the floral nectary in this

Morphological and molecular mechanisms of floral nectary development in Chinese Jujube [PDF]

open access: yesBMC Plant Biology
Background Chinese jujube (Ziziphus jujuba Mill.), also called Chinese date, is one of the oldest and widely cultivated fruit trees with great economic values, which, at least, can be attributed to the melliferous flower with highly developed nectary ...

Variation in floral morphology, histochemistry, and floral visitors of three sympatric morning glory species [PDF]

open access: yesPeerJ
Three morning glory species in the genus Argyreia Lour., A. lycioides (Choisy) Traiperm & Rattanakrajang, A. mekongensis Gagnep & Courchet, and A. versicolor (Kerr) Staples & Traiperm, were found co-occurring and co-flowering. Argyreia mekongensis and A.

Can nectary structure in Laeliinae promote or constrain nectar secretion? [PDF]

open access: yesBMC Plant Biology
The orchid subtribe Laeliinae has an assemblage of morphologically diverse taxa. The diversity in floral morphology of its members can be explained in terms of pollination ecology in that this subtribe contains both entomophilous and ornithophilous ...

Linking genome size variation to phenotypic selection on target traits. [PDF]

open access: yesEcology
Abstract Genome size (GS) is known to be highly variable among angiosperm species. However, this variation can also occur within species. Both interspecific and intraspecific variations in GS have been often found to be linked to phenotypic traits. Therefore, selective pressures acting on these target traits may indirectly shape GS evolution within and

Pollination and Floral Biology of a Rare Morning Glory Species Endemic to Thailand, Argyreia siamensis

open access: yesPlants, 2021
Argyreia siamensis is extremely rare, and very little is known about its reproduction. The species has colorful flowers that seem likely to attract pollinators, but population sizes are typically small (

Comparative Nectary Morphology across Cleomaceae (Brassicales)

open access: yesPlants, 2023
Floral nectaries have evolved multiple times and rapidly diversified with the adaptive radiation of animal pollinators. As such, floral nectaries exhibit extraordinary variation in location, size, shape, and secretory mechanism.

STRUCTURE AND HISTOCHEMISTRY OF THE FLORAL NECTARY OF Bauhinia monandra (FABACEAE)

open access: yesActa Biológica Colombiana, 2023
The structure and histochemistry of the floral nectary of Bauhinia monandra Kurz (Fabaceae) were investigated. Besides possessing medicinal properties, this tree is also used in the recovery of degraded areas and urban arborization.
