Nature Prefers Asymmetrical Pollen Grains, Study Finds News

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.

The present study was intended to assess pollen morphological attributes of selected Asteraceous and Brassicaceous species from tehsil Esa Khel (Mianwali), Punjab using scanning electron microscopy (SEM) and light microscopy (LM) techniques for its sys-tematic and taxonomic significance for correct identification. Pollen from 12 different

Here, we describe methods of transmission electron microscopy (TEM) based on conventional chemical fixation and high-pressure freezing (HPF) and freeze-substitution (FS) to examine the ultrastructure of Arabidopsis pollen grains and pollen tubes.

Picturing Pollen COLORS OF NATURE

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.

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.
