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 ...

Entomologia Experimentalis et Applicata, EarlyView.Using DNA metabarcoding, this study investigates pollen transported by syrphids (Syrphidae) in the Dolomiti Bellunesi National Park and agricultural sites in Northern Italy. The analysis reveals a high diversity of visited plant taxa, including previously undocumented plant–pollinator interactions.

Nectary Specification in Petunia and Arabidopsis [PDF]
The Plant Cell, 2018 Studies of flower development have lots of information about petals, carpels, and stamens, but let’s not forget the birds and the bees—and the flies and moths—and what draws pollinators to insect-pollinated flowers, including flower color, shape, and rewards that provide energy. For example,

Planta, 2017 Main conclusionThe floral nectars were sucrose-dominant; however, nectar protein and amino acid contents differed, indicating that composition of nitrogenous compounds may vary considerably even between closely related plant species, irrespectively of ...

Nectar defense and hydrogen peroxide in floral nectar of Cucurbita pepo
Acta Agrobotanica, 2015 This study was carried out to investigate some similarities between the nectaries of Nicotiana sp. and Cucurbita pepo, such as starch accumulation in the nectary parenchyma, changes in nectary color during maturation, and the production of a large ...

Insect Conservation and Diversity, EarlyView.Local habitat type and hedgerow cover strongly shape bee and wasp richness, but only weakly their reproductive output, outweighing the landscape diversity effects at the 1‐km2 scale. Forests host more wasp but fewer bee species, whereas orchards support high richness of both; bee reproduction patterns are driven by one dominant species, while wasp ...

Variation in Extrafloral Nectary Productivity Influences the Ant Foraging
PLoS ONE, 2017 Extrafloral nectar is the main food source offered by plants to predatory ants in most land environments. Although many studies have demonstrated the importance of extrafloral nectaries (EFNs) to plant defense against herbivores, the influence of EFNs ...

Morphological characters of the flowers and the structure of the nectaries of Acer platanoides L.
Acta Agrobotanica, 2012 The micromorphology of the nectaries and of other elements of the flower was examined by scanning electron microscopy (SEM). The anatomy of the nectaries was determined using light microscopy (LM). The inflorescences of A.

Plant Breeding, EarlyView.ABSTRACT Global food demand is predicted to rise anywhere from 59% to 98% by 2050 because of increasing population. However, the continued depletion of natural resources and increasing biotic and abiotic stresses will continue to pose significant threats to global food security in coming years.
