Journal of Agriculture and Environment for International Development, 2021 Coffee is an important export commodity for the Ethiopian economy and also used for honey production. This study was aimed to identify the effect of temperature and humidity on nectar volume, the nectar secretion dynamics, honey production potentiality ...

International Journal of Horticultural Science, 2006 Intensity of bee visitation (honeybees and wild bees), foraging behaviour of honeybees and nectar parameters (nectar production, sugar concentration, sugar content in nectars) were inspected at 18 apple cultivars for three consecutive years.

NECTAR PRODUCTION IN SEVERAL Campanula SPECIES (CAMPANULACEAE)
Acta Scientiarum Polonorum Hortorum Cultus, 2018 The flowering, nectar production and sugar content were examined in 2012–2013 seasons for three Campanula species (C. persicifolia L., C. glomerata L., C. trachelium L.). The flowers of all studied Campanula spp. are distinctly protandrous; most of them opened between 10.00 and 14.00; only the flowers of C. glomerata continued the opening process until

Nectaries and reproductive biology of croton sarcopetalus (euphorbiaceae) [PDF]
, 2001 Flower morphology, nectary structure, nectar chemical composition, breeding system, floral visitors and pollination were analysed in Croton sarcopetalus, a diclinous-monoecious shrub from Argentina.

Floral nectar production and carbohydrate composition and the structure of receptacular nectaries in the invasive plant Bunias orientalis L. (Brassicaceae) [PDF]
, 2015 The data relating to the nectaries and nectar secretion in invasive Brassicacean taxa are scarce. In the present paper, the nectar production and nectar carbohydrate composition as well as the morphology, anatomy and ultrastructure of the floral ...

The Octadecanoid Pathway, but Not COI1, Is Required for Nectar Secretion in Arabidopsis thaliana
Frontiers in Plant Science, 2018 Over 75% of crop species produce nectar and are dependent on pollinators to achieve maximum seed set, yet little is known about the mechanisms regulating nectar secretion.

Forager bees (Apis mellifera) highly express immune and detoxification genes in tissues associated with nectar processing. [PDF]
, 2015 Pollinators, including honey bees, routinely encounter potentially harmful microorganisms and phytochemicals during foraging. However, the mechanisms by which honey bees manage these potential threats are poorly understood.

Functional Ecology, 2022 Abstract Nectar is a key resource for numerous insects. Despite its importance, nectar productivity has mainly been assessed using one sampling method, in which the volume of nectar produced by a flower is measured after 24 h of isolation from insects (‘measured 24 h volume’ hereafter).

A dataset of nectar sugar production for flowering plants found in urban green spaces
Ecological Solutions and Evidence, 2023 Nectar and pollen are floral resources that provide food for insect pollinators, so quantifying their supplies can help us to understand and mitigate pollinator declines.

The dose makes the poison: have “field realistic” rates of exposure of bees to neonicotinoid insecticides been overestimated in laboratory studies? [PDF]
, 2014 Recent laboratory based studies have demonstrated adverse sub-lethal effects of neonicotinoid insecticides on honey bees and bumble bees, and these studies have been influential in leading to a European Union moratorium on the use of three neonicotinoids,
