Journal: Ekosistemy
Year: 2024

Normally developed pollen grains of the common yew (Taxus baccata L.) are a unicellular gametophyte in the pollen grain shell. According to the existing classification, they are characterized as a spheroidal, small-leptomed, radially symmetrical, sackless, rom small to medium size. Their diameters vary from 15.8 µ to 33.8 µ, with its average statistical value for individual trees from 21.1 µ to 27.2 µ.
