Different strategies and procedures are utilized when researching pollen grains so as to give detailed and precise data about pollen morphology and ultrastructure. The planning techniques utilized rely upon the material to be contemplated, if the pollen grains are to be acquired from on-going bloom material (herbarium sheets, recently gathered) or from different sedimentary shakes, residue or soils (fossil to sub fossil pollen). The depiction of pollen ornamentation relies upon three significant boundaries (1) the understandings of the palynologist, (2) the pollen phrasing applied and (3) the amplification, goal and strategies utilized. The use of various readiness and recoloring techniques and a joined examination with light microscopy, checking and transmission electron microscopy are fundamental for the understanding of pollen characters.

New pollen grains when seen under a light magnifying instrument show up as thick items and uncover just the colour, size, shape and framework of model examples and pollen divider growths. So as to contemplate them all the more intently under a light magnifying instrument to uncover other significant demonstrative pollen morphological characters, it is important to make some extraordinary pollen arrangements. Novel or kept pollen/spore materials are utilized for planning type slides which might be utilized for detailed pollen morphological investigations or for correlations with slide material of airborne pollen/spores to affirm or in any case recognizable proof. Such assortment of slides after some time empowers 'back following' of taxa of pollen and spores for research purposes.

Previously existing examinations, recommended that, treatment of new pollen grains with supreme liquor to break down the waxy covering of the external pollen divider and recoloring them with methyl green. So as to show signs of improvement contrast, utilization of powerless watery cosine was proposed. This strategy is being used for readiness of record (reference) new pollen slides valuable for examination and distinguishing proof of airborne pollen, which are basically untouched.

Acetolysis is one technique of preparing modern pollen and spores for microscopic examination. Acetolysis includes acetylation of pollen grains during which the sugar part of grains is taken out or broken down, hence leaving just the exine with its analytic highlights, for example, ornamentation, gaps and exine definition. The cycle of acetolysis can be alluded as corrosive hydrolysis. It comprises of two cycles: The underlying corrosive hydrolysis response is completed by concentrated sulphuric corrosive. The secondary esterification method is completed by the acidic anhydride. Acetylation, then again indicates just to the second cycle of esterification, yet in the present writing it has gotten inseparable from acetolysis. In general, the sustainability of the acetylation cycle is expanded straightforwardly as the temperature and time is expanded.

In spite of the way that pollen investigation is all the time applied to remains with ineffectively saved pollen, pollen and spore erosion is a greatly neglected subject in palynological research. Lack of information about susceptibility to decay of the individual pollen or spore species may easily lead to misinterpretation of pollen diagrams. Pollen consumption is a confusing idea, involving the impact of different outside components (microbial assault, oxidation, mechanical powers, and high temperature) An exceptional report is required for an appropriate valuation for the impact of every one of these components.
