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.
