Palyno-Morphological Study of Allergenic Flora of Samarkand, Uzbekistan

Abstract

This study set out to look into the palyno-morphological characteristics of specific allergenic species from diverse plant families in Samarkand, Uzbekistan. Six different species i.e. Betula pendula , Fraxinus pennsylvanica , Magnolia × soulangeana , Pinus brutia var. eldarica , Populus alba , Quercus robur were collected, pressed, identified, and then examined under a microscope. Under light microscope, both quantitative and qualitative characteristics of the pollen grains were recorded, including pollen type, pollen size, pollen shape (polar and equatorial view), P/E ratio, mesocolpium distance, exine thickness, colpi type, colpi length, and width. It was found that a warm spring in Uzbekistan causes an early commencement of the vegetative and dusting phases, in contrast to the climatic circumstances of the researched entities’ motherland (cold spring). Studies in aeropalinology and morphology enable the resolution of numerous environmental issues. The findings highlighted the importance of pollen morphology as an identifying aid and showed how the tested species’ palynological characteristics varied. In order to promote future phylogenetic description of the Uzbekistan flora, the current study may help us better understand the palynomorphological traits of native plants. This essay only briefly and inadequately addresses these issues. The information gathered will be used to make an atlas of allergic plants in Samarkand and an electronic warning system for the general public about the spread of pollen from the city’s allergenic plants in the future.
