Evolutionary ecology of nectar [PDF]

open access: yesAnnals of Botany, 2018
Floral nectar is an important determinant of plant-pollinator interactions and an integral component of pollination syndromes, suggesting it is under pollinator-mediated selection. However, compared to floral display traits, we know little about the evolutionary ecology of nectar.

Comparative analyses of the metabolite and ion concentrations in nectar, nectaries, and leaves of 36 bromeliads with different photosynthesis and pollinator types

open access: yesFrontiers in Plant Science, 2022
Floral nectar contains mainly sugars as well as smaller amounts of amino acids and further compounds. The nectar composition varies between different plant species and it is related to the pollination type of the plant. In addition to this, other factors

Floral nectar guide patterns discourage nectar robbing by bumble bees. [PDF]

open access: yesPLoS ONE, 2013
Floral displays are under selection to both attract pollinators and deter antagonists. Here we show that a common floral trait, a nectar guide pattern, alters the behavior of bees that can act opportunistically as both pollinators and as antagonists ...

Comparison of sugars, iridoid glycosides and amino acids in nectar and phloem sap of Maurandya barclayana, Lophospermum erubescens, and Brassica napus. [PDF]

open access: yesPLoS ONE, 2014
BACKGROUND: Floral nectar contains sugars and amino acids to attract pollinators. In addition, nectar also contains different secondary compounds, but little is understood about their origin or function. Does nectar composition reflect phloem composition,

Floral Nectar Chemistry in Orchids: A Short Review and Meta-Analysis

open access: yesPlants, 2021
Nectar is one of the most important flower traits, shaping plant–pollinator interactions and reproductive success. Despite Orchidaceae including numerous nectariferous species, nectar chemistry in this family has been infrequently studied. Therefore, the

The role of jasmonates in floral nectar secretion. [PDF]

open access: yesPLoS ONE, 2010
Plants produce nectar in their flowers as a reward for their pollinators and most of our crops depend on insect pollination, but little is known on the physiological control of nectar secretion.

Do honeybees shape the bacterial community composition in floral nectar? [PDF]

open access: yesPLoS ONE, 2013
Floral nectar is considered the most important reward animal-pollinated plants offer to attract pollinators. Here we explore whether honeybees, which act as pollinators, affect the composition of bacterial communities in the nectar.

The effect of nectar production to the gathering behaviour of honeybees and to the foraging activity of wild bees at apple flowers

open access: yesInternational Journal of Horticultural Science, 2006
Intensity of bee visitation (honeybees and wild bees), foraging behaviour of honeybees and nectar parameters (nectar production, sugar concentration, sugar content in nectars) were inspected at 18 apple cultivars for three consecutive years.
