Sugar composition of floral nectar in sour cherry cultivars

International Journal of Horticultural Science, 2000
The composition of floral nectar in sour cherry cultivars studied in 1997 at Újfehértó was in agreement with our previous data, the three most frequent sugar components being glucose, fructose and sucrose.

Producción de néctar y flores como rasgos compensatorios al robo de néctar en Bouvardia ternifolia (Rubiaceae): experimentos de campo

Botan‪ical Sciences, 2013
El néctar de flores polinizadas por colibríes es usualmente robado por animales no polinizadores, por ello se esperaría que plantas sometidas al robo de néctar presenten distintas estrategias que permitan mitigar los costos asociados.

Nectar ecology of the endemic epiphytic hummingbird-pollinated bromeliad Vriesea altodaserrae: secretion dynamics and pollinator visitation pattern

Acta Botânica Brasílica, 2018
Hummingbirds are the main pollinators of most bromeliad species, whose nectar traits usually respond to the selective pressures imposed by pollinators.

Nectar—but not for parasites [PDF]

Science, 2019
Pollination Bumble bees are vulnerable to parasitism by a flagellated trypanosome (some species of which are important human pathogens). The parasite Crithidia bombi , in combination with environmental stresses, can promote declines in bumble bee populations by reducing foraging and reproductive success. Koch et al. developed a chromatographic pipeline

Variation in Floral Nectar Traits of Four Chestnut (Castanea spp.) Cultivars: Implications for Pollinators and Apiculture

Agriculture
Pollinator nutrition and honey production potential depend on nectar quantity, nectar availability across flowering phases, and sugar concentration. For chestnut (Castanea spp.), cultivar- and flowering phase-specific nectar data remain limited.

Is Self-Incompatibility Related to Nectar Presence in Dendrobium?

Plants
Studies on the gain or loss of nectar during the course of evolution in Dendrobium Sw. (Orchidaceae) are able to provide important information concerning the reproductive biology of this enormous orchid genus and highlight reproductive barriers—in ...
