Floral Nectar Chemistry in Orchids: A Short Review and Meta-Analysis [PDF]
Plants, 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

Sweet solutions: nectar chemistry and quality [PDF]
Philosophical Transactions of the Royal Society B: Biological Sciences, 2022 Abstract Nectar, the main floral reward for pollinators, varies greatly in composition and concentration. The assumption that nectar quality is equivalent to its sugar (energy) concentration is too simple. Diverse non-sugar components, especially amino acids and secondary metabolites, play various roles in nutrition and health of ...

Inter-Individual Nectar Chemistry Changes of Field Scabious, Knautia arvensis [PDF]
Insects, 2020 Nectar is crucial to maintain plant-pollinator mutualism. Nectar quality (nutritional composition) can vary strongly between individuals of the same plant species.

Intraspecific Variation in Nectar Chemistry and Its Implications for Insect Visitors: The Case of the Medicinal Plant, Polemonium Caeruleum L. [PDF]
Plants, 2020 Floral nectar, being a primary reward for insect visitors, is a key factor in shaping plant–pollinator interactions. However, little is known about the variability in nectar traits, which could potentially affect pollinators and the reproduction of the ...

Nectar bacteria affect life history of a generalist aphid parasitoid by altering nectar chemistry [PDF]
Functional Ecology, 2017 Abstract Nectar is a crucial energy resource that strongly mediates the interactions between plants and animal pollinators or plant defenders. Previous research has shown that nectar is frequently colonized by microorganisms, most commonly bacteria and yeasts, which can have a strong impact on nectar chemistry.

Nectar chemistry is not only a plant's affair: floral visitors affect nectar sugar and amino acid composition [PDF]
Oikos, 2021 Floral nectar is the primary reward directly consumed by floral visitors and its chemical composition affects their behaviour and fidelity. In turn, floral visitors are expected to alter floral nectar composition directly or indirectly through the introduction of external contaminants, such as pollen grains and microorganisms.

Agri-environment scheme nectar chemistry can suppress the social epidemiology of parasites in an important pollinator. [PDF]
Proc Biol Sci, 2021 Emergent infectious diseases are one of the main drivers of species loss. Emergent infection with the microsporidian Nosema bombi has been implicated in the population and range declines of a suite of North American bumblebees, a group of important pollinators.

Nectar Chemistry or Flower Morphology-What Is More Important for the Reproductive Success of Generalist Orchid Epipactis palustris in Natural and Anthropogenic Populations? [PDF]
Int J Mol Sci, 2021 The aim of this study was to determine the level of reproductive success (RS) in natural and anthropogenic populations of generalist orchid Epipactis palustris and its dependence on flower structure and nectar composition, i.e., amino acids and sugars.

Nectar secretion in the flowers of comfrey (Symphytum officinale L.) and nectar chemistry
Acta Agrobotanica, 2013 Nectar secretion and nectar chemistry in the flowers of comfrey (Symphytum officinale L.) were examined in the four stages of anthesis: large buds, before pollen exposure: II - freshy opened flowers with the beginning of anther dehiscence: III ...

Extrafloral Nectaries in Woody Plants: Toward an Integrated Framework for Ant-Mediated Plant Defense [PDF]
PlantsExtrafloral nectaries (EFNs)—secretory structures that recruit predatory arthropods as indirect defenders against herbivory—have been studied almost exclusively in herbaceous systems, leaving a critical gap in our understanding of plant defense in woody ...
