The following points highlight four sampler that are conventionally used for trapping pollen grains. The samplers are: 1. Rotorod Sampler 2. Burkard Personal Volumetric Sampler 3. Burkard Seven Day Volumetric Sampler 4. Andersen Two Stage Sampler. 1. Rotorod Sampler: The rotorod sampler (Fig.10.10) was originally devised by Perkins (1957) and has been somewhat modified by Harrington (1959). The device relies [...]
In this article we will discuss about the pollen and spore production and dispersion, pollen sinking speed, pollen degradation, and pollen recycling are important consideration in the study of forensic palynology. 1. Pollen and spore production and dispersion: If one know what the expected production and dispersal patterns of spores and pollen along with their flowering calendar of the plants [...]
The deposit that contains pollen grains and spores suitable for identification and analysis include peats, lake sediments, soil and mor humus. Peats: Peats are the early stage of coalification which are formed due to accumulations of organic detritus largely of plant origin. Peats are developed into a stratified sequence due to the successive deposition of plant parts containing pollen and [...]
