Step by step: Floral structure and developmental changes to the formation of the gynostegium in Apocynaceae s.l.

Plant Biology, Volume 28, Issue 5, Page 1467-1480, August 2026.
Developmental changes in Apocynaceae s.l. reveal progressive reductions in the corolla tube and epipetaly, together with increased staminal tube formation, highlighting shifts in floral integration associated with gynostegium evolution and organization.

Nectar of Ziziphus spina-christi (L.) Willd (Rhamnaceae): Dynamics of Secretion and Potential for Honey Production

Journal of Apicultural Science, 2012
The nectar secretion of Ziziphus flowers was studied by removing and measuring the nectar every four hours, for two consecutive days, from 88 flowers of four trees (‘repeated sampling’).

Structure of the cuniculus nectary in Brassavola flagellaris Barb. Rodr. (Laeliinae Benth., Orchidaceae)

Acta Agrobotanica, 2012
To date, the structure of the cuniculus nectary has not been studied in detail. Furthermore, the secretory mechanism of such nectaries has not been investigated.

Uncovering the Arabidopsis thaliana nectary transcriptome: investigation of differential gene expression in floral nectariferous tissues

BMC Plant Biology, 2009
Background Many flowering plants attract pollinators by offering a reward of floral nectar. Remarkably, the molecular events involved in the development of nectaries, the organs that produce nectar, as well as the synthesis and secretion of nectar itself,

Flower trade-offs derived from nectar investment in female reproduction of two Nicotiana species (Solanaceae)

Acta Botânica Brasílica
Animal-pollinated flowers may orient resources for competing activities, such as nectar production for attracting flower visitors but then saving nectar (through inhibiting nectar production or by final resorption) for the subsequent maturation of fruits

NECTAR PRODUCTION AND POLLEN YIELD OF Echium vulgare L. IN THE CLIMATIC CONDITIONS OF LUBLIN

Acta Scientiarum Polonorum: Hortorum Cultus, 2011
In Poland common viper’s bugloss (E. vulgare L.) is the most common species. E. vulgare belongs to medicinal, ornamental and bee plants, since it is a source of nectar and pollen forage. These flowers are frequently visited by bumblebees and honey bees.

Is Self-Incompatibility Related to Nectar Presence in Dendrobium?

Plants
Studies on the gain or loss of nectar during the course of evolution in Dendrobium Sw. (Orchidaceae) are able to provide important information concerning the reproductive biology of this enormous orchid genus and highlight reproductive barriers—in ...
