Morphological study of allergenic pollen grains in some of the weeds, crop and garden plants in Kermanshah region

The identification of airborne floating pollen, which is displaced by wind or rain, is the subject of the science of Aeropalynology. In this study with the Durham،s method, more than 20 atmospheric pollens, as well as 30 allergenic pollens, were collected from nature and herbarium specimens. For light microscope studies, pollen grains were examined from the polar and equatorial view using the acetolysis method of Erdtman. Also, eight major samples of allergenic pollen were studied using scanningelectron microscopy (SEM). Pollination of studies plants begin from the first week of February, and the maximum concentration of pollens in atmosphere registered between the end of March and the first two weeks of April and the lowest observed during autumn. Pollens were present until the last week of December. The vegetation surrounding the sampling point includes ornamental, non-ornamental trees, shrubs, and herbaceous species. The main pollen types were (Aceraceae, Amaranthaceae, Anacardiaceae, Chenopodiaceae, Compositae, Cupressaceae, Euphorbiaceae, Fagaceae, Gramineae, Moraceae, Oleaceae, Pinaceae, Polygonaceae, Rosaceae, Salicaceae, Ulmaceae). In this study, exine ornamentation of pollen grains was reticulate, granular, echinate, striate, regulate and tuberculate. Hence, human handicrafts in the nature and extent of farms and gardens have caused many weeds in the province of Kermanshah to be found that pollen produced from them is important for allergenicity
