Annotation:

Bee pollen contains high enough nutrition. Bee pollen contains some nutrients such as water, ash, lipid, protein, natural antioxidants, palmitic acid, oleic acid, linoleic acid, and linolenic acid. The high nutrients on bee pollen causes bee pollen to be widely used by many people as a food additive on some food productions. Bee pollen is widely used as a fortificant and substitute material. Bee pollen as a substitute material on the making of crackers. On snack bar making, bee pollen is used as a fortificant material. Bee pollen as a fortificant is also used on the making of milk to increase

Pollen is essential to the development of honey bees. The nutrients in bee pollen vary greatly among plant species. Here, we analyzed the differences in the amino acid compositions of pear (Pyrus bretschneideri), rape (Brassica napus), and apricot (Armeniaca sibirica) pollens and investigated the variation in hemolymph metabolites and metabolic pathways through untargeted metabolomics in caged adult bees at days 7 and 14. The results showed that the levels of five essential amino acids (isoleucine, phenylalanine, lysine, methionine, and histidine) were the highest in pear pollen, and the level

Six supposedly unifloral bee pollens of various botanical origins were characterised by morphometry, SEM, CIE L*a*b* colour parameters and FTIR spectroscopy. Botanical origin and homogeneity of bee pollens were verified by colour and morphology of pollen grains. Water activity, moisture and antioxidant capacity of bee pollens were also evaluated. The results were discussed in terms of connection between botanical origin, composition and antioxidant properties of pollen materials.

Pumpkin is a major cultivated crop particularly in north eastern states of India that depends on insects for the pollination, as the pollens of these plants are large sized and sticky. In the present study, field and lab experiments were conducted to determine the efficiency of the pollinators of pumpkin based on their diversity, relativeabundance and foraging activity. Total four hymenopteran insect pollinators were observed in field viz., bumble bee, little honey bee, Indian honey bee and Digger bee. On the basis of abundance and relative abundance bumble bee was identified as most abundant

Nutritional analysis revealed no significant differences in moisture, protein, and carbohydrate content among the three pollen types.

Annotation:

The study of foraging behaviour in plant-pollinator mutualisms has benefitted from the use of artificial flowers to manipulate floral display traits and the delivery of floral rewards. The two most common floral rewards are pollen and nectar; some pollinators, such as bees, are obliged to collect both for survival and reproduction. While flexible designs for artificial flowers providing nectar rewards abound, useful designs for artificial flowers that dispense pollen are few. This disparity mirrors a heavy emphasis on nectar collection in the study of pollinator foraging behaviour. In this stu

The astonishing diversity of floral form in angiosperm plants is driven in large part by preferences of pollinators for various floral traits, including learned preferences. Remarkably, almost all of a vast literature on learning and memory in pollinators relates to nectar as a reward, even though bees and many flies, beetles, and butterflies must collect pollen. In this study, we asked if bees formed preferences for plant species from which pollen had been collected successfully. Using absolute conditioning, we gave pollen foraging bees experience with plant species that offered only pollen r

Abstract With an ever-changing climate, the decline in the bee population is forcing humans to find supplemental ways to pollinate. A mechanical substitute for a bee needs to be as efficient or better than bee pollination since it will require one person to do the work of many bees. Pollinating one flower at a time would be too time consuming to be effective, so a drone mounted pollen distribution device is the best direction to go to solve this problem. This is a game changing design to prevent a lack of food-producing plant growth as the bee population decreases over time. The design is a lo

In terms of composition, bee pollen contains a large number of different substances such as proteins, carbohydrates and lipids as well as phenolic organic compounds. The protein content is the second most abundant component, its levels (10 to 40%, w/w) depending on the type of plant. Recently, numerous studies have demonstrated the beneficial properties of pollen in promoting health and reducing the risk of developing certain illnesses.

Active sand dunes in Kobuk Valley National Park are a regionally rare and ecologically distinct landscape feature occurring within the northern boreal biome. The sand dunes harbor a rich diversity of plants, including several rare and disjunct species and the endemic Kobuk locoweed (Oxytropis kobukensis). Pollinators associated with these dune plants have not been studied in Kobuk Valley, despite their essential role in transporting pollen which many plants rely on for successful reproduction. In order to gain a better understanding of pollinator diversity and plant-pollinator associations in

The long-term goal of this research is to understand how pollen cope with stress, and identify genes that can be manipulated in crop plants to improve reproductive success during heat stress. The specific aims were to: 1) Compare heat stress dependent changes in gene expression between wild type pollen, and mutants in which pollen are heat sensitive (cngc16) or heat tolerant (apx2-1). 2) Compare cngc16 and apx2 mutants for differences in heat-stress triggered changes in ROS, cNMP, and Ca²⁺ transients. 3) Expand a mutant screen for pollen with increased or decreased thermo-tolerance. These aims

This technical report aims to test the effectiveness of several non-destructive testing (NDT) technologies on wood utility poles to detect deterioration. The project will assess commercially available devices using sound velocity and drilling resistance methods for in-field measurements. The goal is to extend the lifetime of wood poles, prevent unexpected failure, and enhance their in-service life beyond the current 75-year expectation. Despite the benefits of wood poles, it is difficult to obtain reliable deterioration metrics on in-service poles, which can lead to premature decommissioning o

The original objective was to determine the impact of temperature on floral behavior and pollen tube growth and humidity on the proportions of self-, close, and cross-pollinated avocado fruit on trees growing in humid, coastal and dry, inland CA climates. Because self-pollination was demonstrated to be the prevailing mode of pollination in Florida cultivars in warm humid conditions, it was appropriate to determine if similar rates of self-pollination occur in a dry Mediterranean climate present in California. The conclusions of the work were that despite limiting cool temperatures present in V

During the evolutionary process of speciation in plants, naturally occurring barriers to reproduction have developed that affect the transfer of genes within and between related species. These barriers can occur at several different levels beginning with pollination-barriers and ending with hybrid-breakdown. The interaction between pollen and pistils presents one of the major barriers to intra- and inter-specific crosses and is the focus of this research project. Our long-term goal in this research proposal was defined to resolve questions on recognition and communication during pollen-pistil

An archaeological excavation of the protected burial mound Store Vejlhøj in northwestern Denmark was carried out in October-November 2021. The excavation formed part of the ERC-funded research project called ANTHEA, focusing on the deep history of anthropogenic heathlands. It was conducted by Aarhus University in collaboration with Holstebro Museum and Moesgaard Museum. The aim was to test a new method of sampling pollen data from different construction stages in a burial mound and comparing them with pollen data from nearby lake sediments with a view to improving our understanding of prehisto
