“…The varied cuticle ornamentation is one of the taxonomic criteria differentiating species in many families (Orosz-Kovács et al 1990; Chwil et al 2006; Ganeva and Uzunova 2010; Tahir and Rajput 2009; Chwil and Weryszko-Chmielewska 2011). Cuticular striae are involved in the transport of secreted nectar to the accumulation site and protect the secretion from evaporation (Orosz-Kovács and Apostol 1996). The glossy stripes reflecting the sunrays are a light signal determining the entomological attractiveness of flowers (Juniper and Jeffree 1983; Harborne 2014; Wu et al 2011).…”

“…They have been classified as receptacular nectaries (Bernardello 2007; Fahn 1979). This type of nectary has been described in several representatives of Prunus : P. avium , P. armeniaca , P. cerasus , P. domestica , P. dulcis and P. persica (Orosz-Kovács and Apostol 1996; Radice and Galati 2003; Farkas and Zajácz 2007; Chwil 2013).…”

“…The floral nectaries in various taxa of the genus differ in the size, topography, type of stomata and cuticle ornamentation (Fahn 1979; Chwil and Weryszko-Chmielewska 2011; Chwil 2013). Striated cuticular ornamentation on the nectary epidermis surface was observed in P. armeniaca , P. persica , P. cerasus and P. amygdalus , whereas P. domestica was characterised by reticulate ornamentation (Orosz-Kovács 1993; Orosz-Kovács and Apostol 1996; Radice and Galati 2003; Chwil 2013). In terms of cuticle ornamentation, nectaries are divided into mesomorphic glands with sparse striae and xeromorphic ones with denser striae and a thicker cuticle layer (Orosz-Kovács and Apostol 1996; Orosz-Kovács et al 1996, 1998).…”

The stomata in the epidermis of the P. persica nectary were located below guard cells.…”

There is very scanty information concerning the floral nectary structure and nectar secretion in Prunus laurocerasus L. Therefore, the aim of the study was to determine the micromorphology, anatomy and ultrastructure of nectaries; the abundance of nectar production; and the quantitative and qualitative composition of sugars contained in the nectar of two P. laurocerasus cultivars: ‘Schipkaensis’ and ‘Zabeliana’. The nectary structure was studied using light, fluorescence, scanning and transmission electron microscopy techniques. The nectar sugars were analysed with HPLC. The ‘Schipkaensis’ had longer inflorescences with a larger number of flowers and a longer perianth than ‘Zabeliana’. The micromorphological structure of the nectaries in ‘Schipkaensis’ exhibited denser (approx. 39%) and larger (approx. 50%) stomata and thicker (approx. 13%) cuticular striae forming wider bands (approx. 26%) than in ‘Zabeliana’. The results provide new data on the micromorphology, anatomy and ultrastructure of these floral nectaries. Nectary cuticle ornamentation as well as the size, type and density of stomata and stomatal complex topography can have a diagnostic value in Prunus. The nectar sugar weight indicates a significant apicultural value of the cherry laurel, especially in the case of ‘Schipkaensis’. Cherry laurel is an entomophilous species recommended for cultivation in nectariferous zones and insect pollinator refuges; however, climatic conditions eliminating the invasiveness of these plants should be considered.

The distinctive features of floral nectaries facilitate identification of ecological and phylogenetic links between related taxa. The structure and functioning of nectaries determine the relationships between plants, pollinators, and the environment. The aim of the study was to determine and compare the micromorphology of the epidermis in the floral nectaries of six Rubus idaeus cultivars belonging to biennial (‘Glen Ample’, ‘Laszka’, ‘Radziejowa’) and repeated fruiting (‘Pokusa’, ‘Polana’, ‘Polka’) groups. Another objective was to characterize the cuticle ornamentation and stomatal morphology, the anatomy of the nectary epidermis, parenchyma, and sub-nectary parenchyma in the initial nectar secretion phase, as well as the ultrastructure of the nectary epidermis and parenchyma cells in the initial and full nectar secretion phases. The study was carried out using light, fluorescence, scanning and transmission-electron microscopy techniques. Semi-thin and ultrathin sections were used for the microscopic analyses. The cuticular ornamentation and stomatal morphology may be helpful elements in the identification of relatedness between Rubus species. The interaction of the extensive system of endoplasmic reticulum membranes, mitochondria, and Golgi apparatus indicates high metabolic activity, and the fusion of transport vesicles with the membrane suggests granulocrine nectar secretion. The results bring new data to the biology of plants.
