Pollination biology ofNierembergia (Solanaceae)
Plant Systematics and Evolution, 1991A morphological and anatomical description of the floral syndrome ofNierembergia is given, including a survey of the presence of elaiophores in most of its species, chromatography of the floral oils and observations on the pollinator behaviour. The principal pollinators areTapinotaspis spp. includingT.

Pollination Biology in the Callitrichaceae
Systematic Botany, 1992Callitriche is the only genus in which aerial, water surface, and subsurface pollination systems are all reported. Studies of morphology, flowering phenology, patterns of seed production, and pollen tube growth suggest, however, that geitonogamy is the primary mode of pollination. Typical geitonogamy occurs between the aerial flowers of C. marginata, C.

Back to the past for pollination biology
Current Opinion in Plant Biology, 2011Manipulations of the interactions between plants and their floral visitors remain the most successful path to an understanding of floral traits, which may have been shaped by both herbivores and pollinators. By using genetic tools in combination with old-fashioned field work the dual protective/advertisement functions of floral traits are being ...

The pollination biology of a pavement plain: pollinator visitation patterns
Oecologia, 1980The pollination biology of the 20 plant species of a treeless, pavement plain in the San Bernardino Mountains of southern California was studied throughout one flowering season.Several patterns of pollinator activity recorded during the season underline the necessity for noting the activity of all insect pollinators whether specialized, non-specialized,

The saga of pollination biology
2010Developmental events leading to seed set in plants are broadly categorized into three phases of pollination biology: (1) formation of male and female gametes (2) dispersal and deposition of pollen grains on the pistils of individual of the same species and (3) pollen — pistil interaction leading to double-fertilization.

Pollination biology of Annona squamosa L. (Annonaceae): Evidence for pollination syndrome
Scientia Horticulturae, 2012Abstract Pollination biology of Annona squamosa was investigated in the context of functional specialization and pollination syndrome. Hermaphroditic flower exhibited protogynous dichogamy as stigma became receptive a day before anther dehiscence. Flowers produce moderately high number (16,280 ± 324) of spherical and medium size (98.6 μm × 87.3 μm ...

THE POLLINATION BIOLOGY OF TILIA
American Journal of Botany, 1976An anthecological study of Tilia in the Great Plains and New England was undertaken for both native and introduced species. The floral bracts are postulated as being at least as important in pollinator attraction as they are in fruit dispersal. A characteristic sweet odor is always present, but becomes stronger at dusk.

Pollination Biology and Secondary Pollinators in Seven North American Aquilegia Species
International Journal of Plant SciencesPremise of research. The diversity of North American columbine species likely resulted from a radiation promoted by pollinators. Despite previous studies involving plant-pollinator interactions, pollinators have been documented for less than half the 25 North American species, and discussions of floral syndromes have focused on nectar-collecting ...

The pollination biology ofHibbertia stricta (Dilleniaceae)
Plant Systematics and Evolution, 1984The exines of pollen grains ofHibbertia stricta (DC.)R. Br. exF. Muell. (Sect.Pleurandra) wear an oily, yellow pollen coat that stains positively for lipids. The pollen is collected by asocial bees, exclusively. The most common floral foragers are members of the genusLasioglossum (subgenusChilalictus;Halictidae) and they harvest pollen via thoracic ...
