Abstract
Pollen morphology of Pyrus L. spp. genus from West Azerbaijan Province of Iran using light microscope and scanning electron microscope was studied. The species under study included Pyrus syriaca, Pyrus amygdaliformis, Pyrus salicifolia, and Pyrus communis. The measured characteristics were longitudinal axis, transverse axis, length-to-width ratio, depth of groove or pore, shapes, and decorations of wall, and size and type of pollen grain (number of tracks). The images and details of the internal structure of all these four pollen species are provided comprehensively. The results showed that the depth of groove or pore was in the range of 1.0–3.12. The pollen species were small or medium-sized and the most common type among them was type III. The pollen grains of these species were symmetrical with three tracks and their wall decorations were striate and striate and micro-reticulate.
