Water availability shapes temporal patterns of extrafloral nectar secretion and ant visitation to a Neotropical legume. [PDF]

open access: yesPlant Biol (Stuttg)
Mutualistic plants use non‐structural sugar (NSC) to produce carbon‐based resources to reward partners. Then, any factor compromising NSC plant supplies should increase the relative costs of these rewards for plants.

Effect of environmental conditions and genotype on nectar secretion in sunflower (Helianthus annuus L.)

open access: yesOilseeds and fats, crops and lipids, 2020
The sunflower crop provides an important honey flow for beekeepers. In France, beekeepers observed a decrease in honey yield from this crop these past years compared to the 1980s–1990s.

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

open access: yesDiversity
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.

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.

Reproductive biology and nectar secretion dynamics of Penstemon gentianoides (Plantaginaceae): a perennial herb with a mixed pollination system? [PDF]

open access: yesPeerJ, 2017
Background In many plant species, pollination syndromes predict the most effective pollinator. However, other floral visitors may also offer effective pollination services and promote mixed pollination systems.

Nectar secretion in the flowers of comfrey (Symphytum officinale L.) and nectar chemistry

open access: yesActa 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 ...

Dracula’s mistress: removal of blood-red floral nectar results in secretion of more nectar [PDF]

open access: yesPlant Ecology and Evolution, 2020
Background and aims – Flowers of Jaltomata quipuscoae (Solanaceae) secrete blood-red nectar that serves as an energy reward and possible attractant to pollinators.

Climate change reduces nectar secretion in two common Mediterranean plants. [PDF]

open access: yesAoB Plants, 2015
The negative effect of climate change on plants and plant–pollinator interactions is a matter of concern worldwide. The Mediterranean region is considered particularly susceptible to climate warming and the communities of this region will need to face ...

Comparative floral spur anatomy and nectar secretion in four representatives of Ranunculaceae. [PDF]

open access: yesProtoplasma, 2015
Nectaries are common in Ranunculaceae. These secretory structures, however, have not been studied in detail despite their importance in plant-animal interactions, and data relating to the structure of nectary spurs, which are so characteristic of several
