TLDR
A clear link was observed among nectar production pattern, standing crop of nectar, and visitors' behaviour among an Argentinian population of Combretum fruticosum which is self-incompatible and xenogamous.About:

Journal ArticleDOI
Nectar sugar content: estimating standing crop and secretion rate in the field
TL;DR: La quantite de nectar est souvent distribuee irregulierement parmi les fleurs d'une parcelle et the quantite moyenne de sucre par fleur rencontree par un insecte qui butine systematiquement peut depasser celle echantillonnee par un ecologiste non selectif.
Book ChapterDOI
A systematic survey of floral nectaries
TL;DR: The construction of classifications, as well as the understanding of biological diversity, depends upon a careful comparison of attributes of the organisms studied, and the extent to which particular characters are constant or labile will determine their usefulness to systematics.
Journal ArticleDOI
Floral nectaries, nectar production dynamics and chemical composition in six ipomoea species (convolvulaceae) in relation to pollinators.
TL;DR: Floral nectaries and nectar features were compared between six Argentinian Ipomoea species with differences in their pollinator guilds, suggesting that structural constraints may play a major role in the determination of nectar traits of these species.
Journal ArticleDOI
Nectar secretion, reabsorption, and sugar composition in male and female flowers of Cucurbita pepo
TL;DR: By 6 h after flower closure, nectar volume and sugar concentration had decreased drastically, especially in female flowers, suggesting that Cucurbita pepo has the ability to reabsorb most or all unconsumed nectar.

Pollen-ovule ratios: a conservative indicator of breeding systems in flowering plants
TL;DR: The overall objective is to show that PIO's reflect the likelihood of sufficient pollen grains reaching each stigma to result in maximum seed set and suggest that PI O's are integrated with other facets of a plant's breeding system.
Book
Secretory tissues in plants
TL;DR: This is a book that will show you even new to old thing, and when you are really dying of secretory tissues in plants, just pick this book; it will be right for you.
Journal ArticleDOI
What does it cost a plant to produce floral nectar
TL;DR: To the authors' knowledge this is the first demonstration that nectar production entails a cost to a plant in terms of growth and/or reproduction and that both the gains and costs associated with nectarProduction may be estimated in the same 'currency' (seeds).
Journal ArticleDOI
On the calculation of sugar concentration in flower nectar.
TL;DR: The different methods of expressing sugar concentration are here clarified, and the correct methods of converting from one to the other are provided.
Journal ArticleDOI
Sugar concentrations in nectar from hummingbird flowers
TL;DR: It is clear that no statistically significant differences are to be seen between the sugar concentrations of the different flower pollination types in coastal southeast Jamaica, and, if anything, the hummingbird flowers occupy a belowaverage position.
