sculpturing is with tiny scabrae on the ridges [7], but usually appears smooth after
preparation. Pollen
Castanea sativa
Mill. are very small, with a major diameter of
10-12 mm. It is tricolporate with long colpi and small pori. The exine is rugulate,
with soft sculpture. Pollen have parameters: P 14-15 / E 9-11 μm, with three ectoap-
ertures (colpus) and three endoapertures (pore) located in the equator. The exine is
thin, approximately 1-2 μm thick, and the surface is regulate [3].

Scanning electron micrographs of pollen grains are illustrated in Figure 1, 2.
Based on the data of base Polleninfo, pollen grains
Corylus avellana
L. char-
acterized: 1) form: round, triangular in polar survey, oval in equatorial survey; 2)
sizes: polar axis 27.3 (25-31) μm, equatorial axis 28.9 (26-31) μm; 3) appertures:
tripolar pollen grains, pores are 2-3 μm in diametr; 4) pollen shell: thin, rough
exine, thin intina with a very large bulge grows regions (lenticular structures); 5)
additional attribute: granular cytoplasm. The data of our measurements of pollen
grains
Corylus avellana
L. are presented in Table 1.
