Nectar sugar production across floral phases in the Gynodioecious Protandrous Plant Geranium sylvaticum [corrected]. [PDF]

open access: yesPLoS ONE, 2013
Many zoophilous plants attract their pollinators by offering nectar as a reward. In gynodioecious plants (i.e. populations are composed of female and hermaphrodite individuals) nectar production has been repeatedly reported to be larger in hermaphrodite ...

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

The effect of nectar production to the gathering behaviour of honeybees and to the foraging activity of wild bees at apple flowers

open access: yesInternational Journal of Horticultural Science, 2006
Intensity of bee visitation (honeybees and wild bees), foraging behaviour of honeybees and nectar parameters (nectar production, sugar concentration, sugar content in nectars) were inspected at 18 apple cultivars for three consecutive years.

Foliar herbivory increases sucrose concentration in bracteal extrafloral nectar of cotton

open access: yesPLoS ONE, 2021
Cultivated cotton, such as Gossypium hirsutum L., produces extrafloral (EF) nectar on leaves (foliar) and reproductive structures (bracteal) as an indirect anti-herbivore defense.

Nectar production of quince (Cydonia oblonga Mill.) cultivars

open access: yesInternational Journal of Horticultural Science, 2000
Nectar production of six quince cultivars were measured during three consecutive years. The nectar production of quince can be regarded to be small compared to other temperate zone fruit tree species since quince flowers contained 1.07 ± 0.06 mg of ...
