Does the Floral Nectary in Dracocephalum moldavica L. Produce Nectar and Essential Oil? Structure and Histochemistry of the Nectary [PDF]
Biology, 2022 Dracocephalum moldavica is an aromatic plant with a lemon scent and versatile use. Its flowers produce large amounts of nectar, which is collected by bees and bumblebees. The aim of the study was to investigate the structure of the floral nectary in this

Morphological and molecular mechanisms of floral nectary development in Chinese Jujube [PDF]
BMC Plant BiologyBackground Chinese jujube (Ziziphus jujuba Mill.), also called Chinese date, is one of the oldest and widely cultivated fruit trees with great economic values, which, at least, can be attributed to the melliferous flower with highly developed nectary ...

The developmental basis of floral nectary diversity and evolution [PDF]
New PhytologistSummaryNectar is a central bridge between angiosperms and animal mutualists. It is produced by specialized structures termed nectaries, which can be found on different plant organs. Consumption of floral nectar by pollinators and the subsequent transfer of pollen contribute to the reproductive success of both angiosperms and their pollinators.

Can nectary structure in Laeliinae promote or constrain nectar secretion? [PDF]
BMC Plant BiologyThe orchid subtribe Laeliinae has an assemblage of morphologically diverse taxa. The diversity in floral morphology of its members can be explained in terms of pollination ecology in that this subtribe contains both entomophilous and ornithophilous ...

Comparative Nectary Morphology across Cleomaceae (Brassicales)
Plants, 2023 Floral nectaries have evolved multiple times and rapidly diversified with the adaptive radiation of animal pollinators. As such, floral nectaries exhibit extraordinary variation in location, size, shape, and secretory mechanism.

STRUCTURE AND HISTOCHEMISTRY OF THE FLORAL NECTARY OF Bauhinia monandra (FABACEAE)
Acta Biológica Colombiana, 2023 The structure and histochemistry of the floral nectary of Bauhinia monandra Kurz (Fabaceae) were investigated. Besides possessing medicinal properties, this tree is also used in the recovery of degraded areas and urban arborization.

Nectar secretion in a dry habitat: structure of the nectary in two endangered Mexican species of Barkeria (Orchidaceae) [PDF]
PeerJ, 2021 Barkeria scandens and B. whartoniana are endangered, endemic taxa from Mexico. They are epiphytes adapted to dry habitats. Since these plants are xerophytic, their flowers were investigated for structural adaptations to nectar secretion.
