Therefore, in this research, light microscopy and scanning electron microscopy were used to observe seven morphological traits of pollens from 22 common vetch accessions, and residual maximum likelihood and pattern analysis was conducted.

Hitherto such studies have used optical or transmission electron microscopy but here a recently devised preparative technique has enabled pollen development in Cosmos bipinnatus to be studied using the scanning electron microscope. The technique involves freeze-fracturing of osmium fixed, cryoprotected anthers, maceration in dilute osmium.

This study employs scanning electron microscopy (SEM) to delve into the intricate pollen morphology of Cucurbitaceae (Gourd Family) species, unraveling the nuanced details of their structural features. Concurrently, the research investigates the antimicrobial potentials encoded within these pollen.

The electron-micrographs were made using a Quanta 250 microscope (FEI Company) and JEOL 6390LV microscope. Descriptions follow Punt et al. (2007) , and the produced slides were deposited at the pollen library of Plant Micromorphology Laboratory (LAMIV), of the State University of Feira de Santana.

GMS Scanning Electron Microscope Still Image of Pollen Particles

A scanning electrode microscope ( SEM) is a type of electron microscope that produces images of a sample by scanning the surface with a focused beam of electrons. The electrons interact with atoms in the sample, producing various signals that contain information about the surface topography and composition of the 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.

The outermost layer ("exine") is made up of sporopollenin, which is a strong, crosslinked biopolymer 7, while the inner layer ("intine") is composed of elastic, load-bearing cellulose/hemicellulose.

soil analysis. Palynologists rely on light microscopy (LM) to identify and interpret the pollen spectrum of a particular sample. Scanning electron microscopy (SEM) is not normally used for counting and identifying pollen grains. Instead, SEM is mainly used for morphological comparisons and taxonomy where the increased resolution of SEM makes.
