Heritability of nectar production in Echium vulgare [PDF]
Heredity, 2004 Heritabilities of nectar production in the wild species Echium vulgare were estimated as realised heritability under controlled and field conditions. The nectar production of offspring from high- and low-nectar-producing parents was significantly different in both controlled and field conditions, indicating that nectar production is in part genetically

Nectar Analysis Throughout the Genus Nicotiana Suggests Conserved Mechanisms of Nectar Production and Biochemical Action. [PDF]
Front Plant Sci, 2018 We have evaluated the floral nectars of nine species from different sections of the genus Nicotiana. These nine species effectively cover the genus. We found that the nectary glands from these different species showed similar developmental regulation with swelling of nectaries during the first half of development and a distinct color change in the ...

Metabolic and transcriptomic analyses of nectaries reveal differences in the mechanism of nectar production between monocots (Ananas comosus) and dicots (Nicotiana tabacum) [PDF]
BMC Plant BiologyBackground Nectar is offered by numerous flowering plants to attract pollinators. To date, the production and secretion of nectar have been analyzed mainly in eudicots, particularly rosids such as Arabidopsis.

Nectar robbing by the invasive bumblebee Bombus terrestris (Apidae) changes the behavior of native flower visitors of Fuchsia magellanica Lam. (Onagraceae) but not seed set [PDF]
PeerJMutualisms between plants and pollinators may be threatened by nectar robbers, as these animals typically consume nectar without providing the essential pollination service.

Nectar in Plant Species Fragaria vesca L. [PDF]
PlantsFragaria vesca L. is a common plant species in Slovenia. It flowers from May to July. Our study was conducted throughout the 2024 season in two locations at which we sampled nectar in F. vesca flowers. To take the nectar samples, we used microcapillaries.

Interpopulation variation in nectar production in Aconitum columbianum (Ranunculaceae)
Oecologia, 1980 In Aconitum columbianum there are extreme interpopulation differences in rates of nectar secretion per flower. Since nectar sugar concentration varies little among populations, increased nectar secretion results in a greater mass of sugar per flower for pollinator attraction. These differences in the amount of reward offered per flower account at least

Dracula’s mistress: removal of blood-red floral nectar results in secretion of more nectar [PDF]
Plant Ecology and Evolution, 2020 Background and aims – Flowers of Jaltomata quipuscoae (Solanaceae) secrete blood-red nectar that serves as an energy reward and possible attractant to pollinators.

Influence of microclimatic conditions on nectar exudation in Glechoma hirsuta W. K [PDF]
Archives of Biological Sciences, 2005 The nectar production of Glechoma hirsuta W. K. grown under different microclimatic habitat conditions was evaluated by determining the total daily nectar quantity per flower, diurnal dynamics of nectar secretion, the nectar secretion rate, and sugar ...
