Abstract:
Pollen grains of five olive cultivars (Olea europaea L .) were examined, using Scanning
Electron Microscopy (SEM) for identification purposes. Four measurments, polar axis
(P), equatorial diameter (E), P/E ratio and exine patterns were made. Forty pollen grains
of each cultivar were viewed before finally selecting a representative pollen grain. Polar
diameter ranged between ۲۲.۷۶ μm for the ‘Mary’ and ۲۸.۵۸ μm for the ‘Shengeh’ ‘Zard’
and ‘Roghani’ cultivars exhibited incomplete closure of the meshes. ‘Zard’ and ‘Shengeh’
cultivars had thick muri but ‘Roghani’, ‘Mary’ and ‘Fishomi’ possessed thinner muri.
Scanning electron analysis of pollen grain revealed that specific differences including
variation in size and form of the meshes are exist among cultivars. The differences in the
exine pattern may help for the identification of some cultivars.
