Nectary Structure and Nectar Secretion Characteristics Among Various Cultivars of Paeonia lactiflora

Plants
Background: Paeonia lactiflora Pall. produces substantial quantities of nectar during the bud stage. In the production of cut flowers, this nectar attracts contaminants that compromise the quality of the flowers.

Floral nectar production in Helleborus foetidus: an ultrastructural study

Botany, 2012
The floral nectaries of Helleborus foetidus L. were studied using scanning and transmission electron microscopy, as well as light microscopy. Nectaries are tubular and consist of an external epidermis, a photosynthesizing parenchyma, large branches of vascular tissue, a nectar-producing parenchyma, and an internal epidermis.

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,

Blooming biology and sugar efficiency of two cultivars of Lonicera kamtschatica (Sevast.) Pojark.

Acta Agrobotanica, 2012
The studies on the period and abundance of blooming, flower development, as well as nectar productivity of two cultivars of Lonicera kamtschatica (Sevast.) Pojark. were carried out in 2004-2005 in Lublin. The investigated plants bloomed between the third
