A cell wall invertase controls nectar volume and sugar composition [PDF]

The Plant Journal, 2021
SUMMARY Nectar volume and sugar composition are key determinants of the strength of plant–pollinator mutualisms. The main nectar sugars are sucrose, glucose and fructose, which can vary widely in ratio and concentration across species. Brassica  spp.

Nectar chemistry is not only a plant's affair: floral visitors affect nectar sugar and amino acid composition

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.

Nectar in Plant Species Fragaria vesca L. [PDF]

Plants
Fragaria 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.

Nectar sugar composition and concentration in relation to pollination syndromes in Bromeliaceae

Plant Biology, 2008
AbstractA first comprehensive dataset of nectar sugar composition and concentration in Bromeliaceae is presented, covering 111 species belonging to all three subfamilies. Based on this dataset, we examined the relationship between nectar traits and pollination syndromes in the family.

Determination of metabolite differences between loquat nectar and honey by UPLC-MS/MS [PDF]

PeerJ
Honey is a widely consumed natural agricultural product. Honey bees produce honey by collecting nectar from different flowers and then metabolising it to form honey which is stored in the hive.

Nectar Dynamics and Pollinators Preference in Sunflower

Insects, 2022
Nectar is a complex biochemical substance secreted with particular rhythm by flower nectaries. Nectar is the base of a mutualism in which pollinators consume nectar, as food source, and are involuntarily responsible for the transport of pollen and ...

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

Frontiers 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 Chemistry in Orchids: A Short Review and Meta-Analysis

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

Nectar‐inhabiting microorganisms influence nectar volatile composition and attractiveness to a generalist pollinator [PDF]

New Phytologist, 2017
Summary The plant microbiome can influence plant phenotype in diverse ways, yet microbial contribution to plant volatile phenotype remains poorly understood. We examine the presence of fungi and bacteria in the nectar of a coflowering plant community, characterize the volatiles produced by common nectar microbes and examine their influence on ...

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

PLoS 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,
