Nectary Structure and Nectar Secretion Characteristics Among Various Cultivars of Paeonia lactiflora

Plants
Background: Paeonia lactiflora Pall. produces substantial quantities of nectar during the bud stage. In the production of cut flowers, this nectar attracts contaminants that compromise the quality of the flowers.

Sex-Dependent Variation of Pumpkin (Cucurbita maxima cv. Big Max) Nectar and Nectaries as Determined by Proteomics and Metabolomics

Frontiers in Plant Science, 2018
Nectar is a floral reward that sustains mutualisms with pollinators, which in turn, improves fruit set. While it is known that nectar is a chemically complex solution, extensive identification and quantification of this complexity has been lacking ...

Moving I`iwi (Vestiaria coccinea) as a Surrogate for Future Translocations of Endangered `Akohekohe (Palmeria dolei) [PDF]

, 2010
Translocations often play an important role in the recovery of endangered species. To assess feasibility for translocation of endangered `Akohekohe (Palmeria dolei), we conducted an experimental translocation of I`iwi (Vestiaria coccinea) from east to ...

Do Flowers Reabsorb Nectar?

Functional Ecology, 1991
The rate of change in the standing crop of nectar allowed to accumulate in flowers, described here as the apparent secretion rate, can be resolved into two components: gross secretion rate and apparent reabsorption rate. A simple model shows how changes in these component rates may affect the apparent secretion rate.

Longitudinal Videofluorographic Dysphagia Measures in Progressive Supranuclear Palsy

Movement Disorders Clinical Practice, EarlyView.
Abstract Background Dysphagia can lead to fatal aspiration pneumonia in progressive supranuclear palsy (PSP). Little is known about the longitudinal progression of dysphagia or whether it differs across PSP clinical variants. Objectives To characterize longitudinal changes in dysphagia across PSP variants and determine relationships with disease ...

Self-pollination by sliding pollen in Caulokaempferia coenobialis (Zingiberaceae) [PDF]

, 2005
Caulokaempferia coenobialis (Zingiberaceae) forms dense populations on steep cliffs in shady, humid monsoon forests in south China. It produces few consecutively opening bright yellow flowers that are 3 cm long and oriented parallel to the ground.

Generalist‐pollinated Arabis alpina exhibits floral scent variation at multiple scales

Nordic Journal of Botany, EarlyView.
Plants that depend on animals for reproduction often use complex floral traits to attract pollinators. Floral scent is recognized as part of the pollinator attraction module and can be shaped by plant‐pollinator interactions. In recent decades, research has started to reveal the dynamic properties of floral scent, identifying patterns of spatial and ...

Effect of Abiotic Factors on Nectar Quality and Secretion of Two Early Spring Species, Galanthus nivalis L. and Helleborus niger L.

Diversity
Floral nectar is mainly a reward in the form of food for pollinators. In early spring, when snow can still be present, pollinators have trouble finding food.

Temporal and spatial variation in bacterial communities of “Jonagold” apple (Malus x domestica Borkh.) and “Conference” pear (Pyrus communis L.) floral nectar

MicrobiologyOpen, 2019
Production of many agricultural crops and fruits strongly depends on pollinators. For instance, pome fruits such as apple and pear are highly dependent on pollination for fruit set, fruit quality, and yield.

The Octadecanoid Pathway, but Not COI1, Is Required for Nectar Secretion in Arabidopsis thaliana

Frontiers in Plant Science, 2018
Over 75% of crop species produce nectar and are dependent on pollinators to achieve maximum seed set, yet little is known about the mechanisms regulating nectar secretion.
