The complexity of nectar: secretion and resorption dynamically regulate nectar features
Die Naturwissenschaften, 2007In this paper, we review the phenomenon of nectar resorption, focusing on its physiological and ecological meaning. Nectar resorption is a phenomenon that has long been known but was rarely reported until the 1990s. It has more recently been demonstrated in several species by various direct and indirect methodologies. It has generally been demonstrated

Nectar secretion inAbutilon: a new model
Protoplasma, 1988Nectary trichomes ofAbutilon striatum secrete copious amounts of sucrose, fructose and glucose. The nectar emerges from transient pores in the cuticle overlying the trichome tip cells. Calculations of the required transmembrane fluxes, either across the tip cell plasmalemma or across the cell membrane of the whole trichome, give very high rates ...

SummaryNectar secretion was studied in dandelion growing in a crested wheat-grass field in the Peace River region of Alberta, Canada. The average number of flowers produced daily in an area 1 m2 was 59·2 in 1981 and 8·9 in 1982. Most flowers opened in the morning and closed in the afternoon.

Nectary Structure, Nectar Secretion Patterns and Nectar Composition in Two Helleborus Species
Plant Biology, 1999Abstract: The morphological and cytological characteristics of nectaries of Helleborus foetidus and H. bocconei during the secretory period are reported. The nectaries are derived from modified petals and secrete nectar continuously for about 20 days; they consist of a single layered epidermis, nectar‐producing parenchyma and photosynthesizing ...

Dilute Nectar in Dry Atmospheres: Nectar Secretion Patterns in Aloe castanea (Asphodelaceae)
International Journal of Plant Sciences, 2005Aloe species commonly flower during the winter dry season in southern Africa and produce abundant dilute nectar. We investigated variability in nectar production and availability in Aloe castanea because evaporation is more likely from its open flowers than from the tubular flowers of most other Aloe species.

A model for nectar secretion in animal-pollinated plants
Evolutionary Ecology, 1993A game theoretic model was developed for nectar secretion in animal-pollinated plants in order to examine how the total amount of resources allocated to flowers affects the spread of nectarless plants. It was assumed that pollinators concentrate on patches whose nectar rewards are relatively large compared to other patches and if pollinators visit a ...
