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 ...
