Ants as flower visitors : floral ant-repellence and the impact of ant scent-marks on pollinator behaviour [PDF]

, 2012
As flower visitors, ants rarely benefit a plant, commonly disrupting pollination by deterring other flower visitors, or stealing nectar. This thesis examines three aspects of ant-flower interactions, focusing on the occurrence of floral traits that ...

Intraspecific variability of floral nectar volume and composition in rapeseed (Brassica napus L. var. oleifera)

Frontiers in Plant Science, 2016
Numerous angiosperms rely on pollinators to ensure efficient flower fertilization, offering a reward consisting of nourishing nectars produced by specialized floral cells, known as nectaries.

Inter-Individual Nectar Chemistry Changes of Field Scabious, Knautia arvensis

Insects, 2020
Nectar is crucial to maintain plant-pollinator mutualism. Nectar quality (nutritional composition) can vary strongly between individuals of the same plant species.

Temporal and spatial variation in bacterial communities of “Jonagold” apple (Malus x domestica Borkh.) and “Conference” pear (Pyrus communis L.) floral nectar

MicrobiologyOpen, 2019
Production of many agricultural crops and fruits strongly depends on pollinators. For instance, pome fruits such as apple and pear are highly dependent on pollination for fruit set, fruit quality, and yield.

Assessing risks and benefits of floral supplements in conservation biological control [PDF]

, 2010
The use of flowering field margins is often proposed as a method to support biological control in agro-ecosystems. In addition to beneficial insects, many herbivores depend on floral food as well.

Sex-Dependent Variation of Pumpkin (Cucurbita maxima cv. Big Max) Nectar and Nectaries as Determined by Proteomics and Metabolomics

Frontiers in Plant Science, 2018
Nectar is a floral reward that sustains mutualisms with pollinators, which in turn, improves fruit set. While it is known that nectar is a chemically complex solution, extensive identification and quantification of this complexity has been lacking ...

Diversity and distribution of microbial communities in floral nectar of two night-blooming plants of the Sonoran Desert.

PLoS ONE, 2019
Nectar-inhabiting microbes are increasingly appreciated as important components of plant-pollinator interactions. We quantified the incidence, abundance, diversity, and composition of bacterial and fungal communities in floral nectar of two night ...

Comparison of Biochemical Constituents and Contents in Floral Nectar of Castanea spp.

Molecules, 2020
Pollination is essential for efficient reproduction in pollinator-dependent crops that rely on the attraction of pollinators to flowers. Especially, floral nectar is considered to be an important factor attracting pollinator like honey bees, but ...

Differential effects of jasmonic acid treatment of Brassica nigra on the attraction of pollinators, parasitoids, and butterflies [PDF]

, 2008
Herbivore-induced plant defences influence the behaviour of herbivores as well as that of their natural enemies. Jasmonic acid is one of the key hormones involved in both these direct and indirect induced defences.
