Morphometric analysis of nectaries and their potential use in the taxonomy of the Jovibarba heuffelii complex (Crassulaceae) [PDF]
Archives of Biological Sciences, 2015 The aim of this study was to quantify the morphological variation of nectaries among 14 populations of Jovibarba heuffelii based on multivariate statistics, and to establish whether nectaries possess taxonomic significance for differentiating ...

Structure of nectaries of Malus sylvestris (L.) Mill.
Acta Agrobotanica, 2012 The structure of floral nectary of Malus sylvestris was examined using light and scanning electron microscopy. Nectaries in M. sylvestris flowers were situated on the adaxial surface of the receptacle, between the style and the base of filaments.

Revista Chilena de Entomología, 2022 Almost all reduviids are predators; however, recent observations have shown that certain reduviids, particularly members of tribe Harpactorini (Harpactorinae) may be associated with specific plants as a strategy of predation and complementary nectarivory.

Acta Botânica BrasílicaNectaries are specialized structures that secrete nectar. Several species of Chamaecrista possess nectaries on the petiole, which have been shown to vary widely in morphology and the chemical nature of their secretion.

The pennycress (Thlaspi arvense L.) nectary: structural and transcriptomic characterization
BMC Plant Biology, 2017 Background Pennycress [Thlaspi arvense L (Brassicaceae)] is being domesticated as a renewable biodiesel feedstock that also provides crucial ecosystems services, including as a nutritional resource for pollinators.

Acta Societatis Botanicorum Poloniae, 2014 The extrafloral nectaries (30-50) are found on the upper surface of the lamina in Macaranga peltata. Glandular trichomes are restricted to the lower surface while eglandular trichomes are observed on all vegetative and reproductive organs.

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,
