Floral nectar production: what cost to a plant?
Biological Reviews, 2023ABSTRACTFloral nectar production is central to plant pollination, and hence to human wellbeing. As floral nectar is essentially a solution in water of various sugars, it is likely a valuable plant resource, especially in terms of energy, with plants experiencing costs/trade‐offs associated with its production or absorption and adopting mechanisms to ...

Plants growing in heavy-metal-rich soils can accumulate metals into their nectar. Nectar chemical composition can alter foraging behavior of floral visitors (including pollinators and floral antagonists) and further affect plant reproductive fitness.

Proceedings / Indian Academy of Sciences, 1986
Nectar composition (sugars and amino acids) of 100 species representing 83 genera from 34 families of angiosperms have been studied. The distribution of the 3 common sugars viz., sucrose, fructose and glucose in nectars of the species studied can be broadly divided into 6 types, based on the presence or absence of any one of the sugars viz sucrose ...

Nectar resorption and plant reproduction
2023Nectar removal and nectar resorption are processes that can impact a plant's reproductive success, but their overall costs and benefits have not been fully assessed in terms of complete reproductive outputs. This study is the first attempt to compare the nectar production resorption with plant fitness in the same currency of ‘energy’.

Larval Food-plants and Nectar Flowers
2008Butterfly caterpillars feed on the leaves or sometimes flower-parts of green plants and the adult insects visit flowers for nectar, and in a few instances pollen. Whilst most butterflies are not very particular about their sources of nectar, taking it where and when available, their selection of plant species on which to lay their eggs is specialized ...

Plant biology: Nectar bacteria grow by germinating and bursting pollen
Current Biology, 2021Microbial residents of floral nectar must survive in a carbohydrate-rich yet seemingly nitrogen-poor environment. A new study shows that Acinetobacter spp., common nectar-inhabiting bacteria, differentially induce the pollen commonly found in nectar to germinate and burst, releasing nutrients for microbial growth.

A novel role for proline in plant floral nectars
Naturwissenschaften, 2006Plants offer metabolically rich floral nectar to attract visiting pollinators. The composition of nectar includes not only sugars, but also amino acids. We have examined the amino acid content of the nectar of ornamental tobacco and found that it is extremely rich (2 mM) in proline.

Patterns of plant visitation by nectar-feeding lizards
Oecologia, 1995Geckos in the genus Hoplodactylus visit flowers to feed on nectar. I examined the patterns of flower visitation exhibited by two gecko species (H. maculatus and H. duvauceli) having access to two plant species: pohutukawa (Metrosideros excelsa: Myrtaceae) and flax (Phormium tenax: Agavaceae).

Why are some plant–nectar robber interactions commensalisms?
Oikos, 2018Many plants that bear hidden or recessed floral nectar experience nectar robbing, the removal of nectar by a floral visitor through holes pierced in the corolla. Although robbing can reduce plant reproductive success, many studies fail to find such effects.

Nectar dispersion patterns in three Australian plant species
Australian Journal of Ecology, 1987Abstract Standing crops of floral nectar were measured from three species of plants: Dampiera stricta, Goodenia bellidifolia and Aotus ericoides. The amount of nectar in nearest neighbour blossoms in nine of the 10 samples were significantly correlated with one another suggesting that patches of high and low reward quality exist in these species.
