When viewing pollen grains under stereo microscope, it is advisable to view treated pollen (washed using a little alcohol) and untreated grains separately in order to see the difference. The procedure involves the following simple steps: Wash the pollen grains using alcohol and place the sample on a microscope slide (also keep an unwashed sample)

In this work, the suitability of three microscopic techniques for automatic analysis of pollen grains was studied. 2D and 3D morphological characteristics, textural and colour features, and extended depth of focus characteristics were used for the pollen discrimination.

There are several ways to observe pollen with a microscope. In the literature, the embedding of pollen in glycerine in combination with a dye such as basic fuchsine is often described. The dye is used to enhance the visibility of certain pollen structures.

Practice using a microscope to see what pollen looks like, to observe the diversity of pollen morphology. Compare reference pollen from flowers with local pollen samples. Pollen is composed of pollen grains which are the male gamethophytes of (seed producing) plants (gymnosperms and angiosperms).

False-colored scanning electron micrographs show the diverse ornamentation patterns on the surfaces of pollen from different species.

2024年4月11日 · Scanning Electron Microscope (SEM): The scanning electron microscope is the primary tool used for imaging pollen samples at high magnifications and resolutions. It allows researchers to observe the surface topography and three-dimensional structure of …

With a x100 microscope you will just be able to see the grains of pollen. Using x400 you will be able to see some identifying features. You will need x1000 to see the level of detail shown here. You should be able to find plants in flower, with pollen available, at most times of the year. For example (with the approximate week of flowering):

Pollen grains present a variety of challenges to study and interpret under the microscope. Most pollen requires at least a 10X if not up to a 40X objective and higher to study both the gross structure and fine details.

Observe the pollen under the microscope using a x10 lens, then a x40 lens. Label the slide with the flower’s name. Repeat the above with different flower types. Describe any modifications you made to the procedure and explain why you did so. Use a suitable method to describe features of pollen you observed.

2025年1月8日 · SEM is able to reveal the incredible diversity in pollen structures from sprinkle doughnut nacho waterlilies to lavender that resemble tiny flowers, daffodil grains on petals that resemble an otter in the sea, and daisy pollen with a spiky, virus-like appearance.
