Summary
Microscopic pollen analysis of herbaceous flora from Samarkand reveals significant variations in shape, size, and exine ornamentation. These micromorphological features are crucial for accurate taxonomic identification of plant species.
Area of Science:
- Botany
- Plant Taxonomy
- Palynology
Background:
- Microscopic techniques are vital for plant systematics and taxonomic problem-solving.
- Pollen morphology offers valuable data for plant identification and classification.
Purpose of the Study:
- To evaluate microscopic pollen morphological attributes of herbaceous flora from Samarkand, Uzbekistan.
- To explore new approaches to pollen imaging and visualization for taxonomic studies.
Main Methods:
- Collected and identified 13 herbaceous species from 11 families.
- Acetolyzed pollen for visualization under light and scanning electron microscopy.
- Analyzed pollen shape, size, aperture type, exine ornamentation, and thickness.
Main Results:
- Observed diverse pollen morphotypes: prolate spheroidal, spheroidal, prolate, and oblate.
- Identified six pollen types, including tricolporate, tricolpate, pantoporate, sulcate, and hexacolpate.
- Documented extensive variations in exine ornamentation and thickness across species.
Conclusions:

A scanning electron microscope (SEM) is used to study the surface features of a sample by using an electron beam that scans the sample surface in a two-dimensional manner. Typically, areas between ~1 centimeter to 5 micrometers in width can be imaged. SEM can be used to image bacteria, viruses, tissues as well as larger samples like insects. Conventional SEM gives a magnification ranging from 20X to 30,000X and spatial resolution of 50 to 100 nanometers.

9.1K
The wavelengths of visible light ultimately limit the maximum theoretical resolution of images created by light microscopes. Most light microscopes can only magnify 1000X, and a few can magnify up to 1500X. Electrons, like electromagnetic radiation, can behave like waves, but with wavelengths of 0.005 nm, they produce significantly greater resolution up to 0.05 nm as compared to 500 nm for visible light. An electron microscope (EM) can create a sharp image that is magnified up to 2,000,000X.

The early pioneers of microscopy opened a window into the invisible world of microorganisms. In 1830, Joseph Jackson Lister created an essentially modern light microscope. The 20th century saw the development of microscopes that leveraged nonvisible light, such as fluorescence microscopy that uses an ultraviolet light source and electron microscopy that uses short-wavelength electron beams. These advances significantly improved magnification, image resolution, and contrast. By comparison, the...

Immunoelectron microscopy utilizes immunogold labeling of endogenous proteins with specific antibodies to detect and localize these proteins in cells and tissues. The procedure provides insights into the distribution and quantification of protein under different stimulation conditions offering clues about their functions. Conjugating highly electron-dense gold particles with primary or secondary antibodies allow antigen detection on and within cells, with high resolution and specificity.

5.4K
To be visualized by an electron microscope, either transmission or scanning, biological samples need to be fixed (stabilized) so the electron beam does not destroy them and dried thoroughly (desiccated/dehydrated) so the vacuum does not affect them. Fixation needs to be done as quickly as possible because the sample properties will start changing as soon as it is removed from its natural environment. For example, in a tissue sample, the oxygen levels begin decreasing, causing an altered...
