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.

Floral trait variation across individual plants within a population enhances defense capability to nectar robbing

open access: yesPlant Diversity, 2023
Floral trait variation may help pollinators and nectar robbers identify their target plants and, thus, lead to differential selection pressure for defense capability against floral antagonists.

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 ...

Heritability of nectar production in Echium vulgare [PDF]

open access: yesHeredity, 2004
Heritabilities of nectar production in the wild species Echium vulgare were estimated as realised heritability under controlled and field conditions. The nectar production of offspring from high- and low-nectar-producing parents was significantly different in both controlled and field conditions, indicating that nectar production is in part genetically

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

Nectar production in species of the Genus galanthus L. (Amaryllidaceae) from Serbia [PDF]

open access: yesGlasnik Šumarskog Fakulteta: Univerzitet u Beogradu, 2014
As a contribution to the study of the melliferous flora of Serbia, nectar production in two species of the genus Galanthus L. (G. nivalis L., and G. elwesii Hook.) was investigated.

Patterns of Nectar Production in Asclepias curassavica (Apocynaceae))

open access: yesJournal of Pollination Ecology, 2019
Milkweeds are important nectar resources for insects in the New World. In addition, nectar is the germination medium for milkweed pollen. This study is the first controlled, greenhouse examination of patterns of nectar production in a milkweed species ...

Differential effects of jasmonic acid treatment of Brassica nigra on the attraction of pollinators, parasitoids, and butterflies [PDF]

open access: yes, 2008
Herbivore-induced plant defences influence the behaviour of herbivores as well as that of their natural enemies. Jasmonic acid is one of the key hormones involved in both these direct and indirect induced defences.

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.
