THE RELATION BETWEEN HONEY STORAGE AND POLLEN GRAINS AT HONEY BEES WORKERS (Apis Mellifera L) ACTIVITY ON WANDERING AND COLLECTION TO PROVIDE FOOD NECESSARY FOR THE GROWTH AND DEVELOPMENT OF THE COLONY [PDF]

Mesopotamia Journal of Agriculture, 2007
Effect of storing honey and pollen grains for bees workers on groups of honey bees (strong. medium. weak) show that the best area was for the strong groups and the least for the weak ones.

Multifunctional Bracts in the Dove Tree Davidia involucrata (Nyssaceae:Cornales) [PDF]

, 2008
Although there has been much experimental work on floral traits that are under selection from mutualists and antagonists, selection by abiotic environmental factors on flowers has been largely ignored.

Pollen grains induce a rapid and biphasic eczematous immune response in atopic eczema patients [PDF]

, 2008
Introduction: Eczematous reactions to type I allergy-inducing antigens are documented in a subgroup of patients with atopic eczema. Yet, the underlying immunological mechanisms are not well understood.

Pollen morphology of selected species of the subfamily Bombacoideae (Malvaceae sensu lato)

Acta Botânica Brasílica, 2014
We analyzed the pollen grains of 11 species within the subfamily Bombacoideae. The pollen grains were acetolyzed, after which they were analyzed and photographed under light microscopy. Unacetolyzed pollen grains were analyzed and photomicrographed under

Proline synthesis in developing microspores is required for pollen development and fertility [PDF]

, 2018
Background: In many plants, the amino acid proline is strongly accumulated in pollen and disruption of proline synthesis caused abortion of microspore development in Arabidopsis.

Mesoscale Atmospheric Transport of Ragweed Pollen Allergens from Infected to Uninfected Areas [PDF]

, 2016
Allergenic ragweed (Ambrosia spp.) pollen grains, after being released from anthers, can be dispersed by air masses far from their source. However, the action of air temperature,humidity and solar radiation on pollen grains in the atmosphere could ...

Determination of cardinal temperatures for sugar apple ( Annona squamosa L.)

Ciência e Agrotecnologia, 2016
The sugar apple is highly dependent on the pollination and fruit tree pollen performance is crucial for successful fertilization and fruit set. The objective of this study was to determine the cardinal temperatures for in vitro pollen grains germination ...

Pollen grains for oral vaccination [PDF]

Journal of Controlled Release, 2014
Oral vaccination can offer a painless and convenient method of vaccination. Furthermore, in addition to systemic immunity it has potential to stimulate mucosal immunity through antigen-processing by the gut-associated lymphoid tissues. In this study we propose the concept that pollen grains can be engineered for use as a simple modular system for oral ...

Boron deficiency responses in maize (Zea mays L.) roots

Journal of Plant Nutrition and Soil Science, EarlyView., 2023
Abstract Background Boron (B) is an essential micronutrient for plants. Dicot plants respond to insufficient B supply by altering root architecture and root hair growth. How root systems of rather low‐B demanding monocot species such as maize (Zea mays L.) respond to B deficiency in terra has not been experimentally resolved, yet.

Identifying Urban Sources as Cause of Elevated Grass Pollen Concentrations using GIS and Remote Sensing [PDF]

, 2013
We examine here the hypothesis that during flowering, the grass pollen concentrations at a specific site reflect the distribution of grass pollen sources within a few kilometres of this site.We perform this analysis on data from a measurement campaign in
