Abstract

A comparative scanning electron microscopy study and biometric analysis on pollen of 27 Bulgarian and foreign seedless grape cultivars have been performed. Both the degree of similarity and the specific differences in exine ultrastructural organisation and the aperture complex were established. In all investigated cultivars, pollen grains were from elongated elliptical to oval-spheroidal, tricolporate in shape. The exine surface is in low relief, with perforations and crest undulations in the mesocolpiums. It was concluded that the type of exine sculpturing, the length of polar and equatorial axes and colp could be used as additional microstructural parameters in cultivar identification of seedless grapes.
