On the mechanisms of nectar secretion: revisited [PDF]

open access: yesAnnals of Botany, 2010
Models of nectar formation and exudation in multilayered nectaries with modified stomata or permeable cuticle are evaluated. In the current symplasmic model the pre-nectar moves from terminal phloem through the symplasm into the apoplasm (cell walls and intercellular spaces) with nectar formation by either granulocrine or eccrine secretion and its ...

Quantifying Nectar Secretion Potential of Hygrophila auriculata (Schum.), Heine (Acanthaceae), and Salvia leucantha Cav. (Lamiaceae) for Honey Production

open access: yesAdvances in Agriculture, 2022
The study was conducted to quantify the nectar secretion dynamics, and honey production capacity of Hygrophila auriculata and Salvia leucantha. One day before nectar collection, a group of flowers was enclosed with mesh bags to measure accumulated nectar

Continuous and discontinuous nectar secretion in some pear cultivars

open access: yesInternational Journal of Horticultural Science, 2000
Hourly nectar secretion was studied in five pear cultivars between 1997-1999. Some cultivars (e.g. ‘Csákvári téli') secreted nectar continuously during the whole day, offering both nectar and pollen for pollinating insects.

Nectary development in Cleome violacea

open access: yesFrontiers in Plant Science, 2023
Nectaries are a promising frontier for plant evo-devo research, and are particularly fascinating given their diversity in form, position, and secretion methods across angiosperms.

Effect of weather factors and nitrogen application on nectar secretion and honey production potential in sunflower

open access: yesJournal of Agrometeorology, 2020
Sunflower is a highly important bee floral crop. The nectar secretion governs this parameter and is greatly influenced by cultivar, environmental factors and fertilizer application.

Nectar Sugar Modulation and Cell Wall Invertases in the Nectaries of Day- and Night- Flowering Nicotiana

open access: yesFrontiers in Plant Science, 2018
Nectar composition varies between species, depending on flowering time and pollinator type, among others. Various models of the biochemical and molecular mechanisms underlying nectar production and secretion have been proposed.

Metabolomic Profiling of Nicotiana Spp. Nectars Indicate That Pollinator Feeding Preference Is a Stronger Determinant Than Plant Phylogenetics in Shaping Nectar Diversity

open access: yesMetabolites, 2020
Floral nectar is a rich secretion produced by the nectary gland and is offered as reward to attract pollinators leading to improved seed set. Nectars are composed of a complex mixture of sugars, amino acids, proteins, vitamins, lipids, organic and ...

Sugary secretions of wasp galls: a want-to-be extrafloral nectar? [PDF]

open access: yesAnnals of Botany, 2017
The most widespread form of protective mutualisms is represented by plants bearing extrafloral nectaries (EFNs) that attract ants and other arthropods for indirect defence. Another, but less common, form of sugary secretion for indirect defence occurs in galls induced by cynipid wasps.
