Pollen

the age of the plants and were pollinated till the pollen was easily seen to the naked eye. For the effect on male flowers, around 6 plants in 5 plots were counted as well, from an age bracket of 1-day to 6-days. Upon dehiscence, the age of the anthers were recorded. Then the anthers were aged on three flowers that were bagged, incubated for 24 hours on agar plates, then the frequency of germinated pollen tubes were counted. To test pistil and pollen viability given different ages, flowers of…

This article examines the effect of different types of spring tree pollens on the number of sales of over-the-counter allergy medication and on the number of visits from the asthma syndrome emergency department. Nine different types of tree pollens were measured and analyzed throughout the spring season in New York City from 2002 to 2012. The number of allergy medication sold was collected from various drugstores and data on asthma syndrome emergency department visits was gathered from hospitals…

instead of using pollen, beekeepers started using substitutes to feed the bees. Huang states, “Honey bees are unequivocally the most important insect pollinator for humankind” (2012). If society does not take care of its bees then we will not have a future and the best way to do that is through pollen. There are types of amino acids that a bee can only digest them as free amino acids or they would have to be digested from proteins which is found in pollen (Huang, 2012). A piece of pollen…

1). Pollen samples were collected 59 with depth intervals of ca. 50 cm. Sample preparation included treatment with HCl and KOH, sieving (meshes 120 µm), 60 treatment with HF, acetolysis (7 min), and mountingin silicone oil [20]. Counting was with a Zeiss binocular microscope 61 with a magnification of 400 times; larger magnifications were used for the identification of problematic palynomorphs. 62 63 Example pollen diagrams with selected depth intervals and pollen types are presented…

colonies. Such findings are of great concern given the large numbers and high levels of pesticides found in honey bee colonies. Thus it is crucial to determine how field-relevant combinations and loads of pesticides affect bee health. We collected pollen from bee hives in seven major crops to determine 1) what types of pesticides bees are exposed to when rented for pollination of various crops and 2) how field-relevant pesticide blends affect bees’ susceptibility to the gut parasite Nosema…

pairs of wings, six legs and two compound eyes. Moreover, there are three kinds of honey bees in a hive, one Queen bee, many worker bees and a few drones. They have different chore in the hive.
