RESEARCHES REGARDING THE VARIABILITY OF SOME MORPHOLOGICAL CHARACTERS OF THE POLLEN AT AMPELOPSIS ACONITIFOLIA BGE. AND A. BREVIPEDUNCULATA (MAXIM.) TRAUTV.

SILVICA PÄ‚DUREANU

Abstract: The paper present the variability of some pollen characters at two taxons belonging to Ampelopsis aconitifolia Bge.and A. brevipedunculata (Maxim.) Trautv. species. The researches had in view the form variability, sporodermis relief, diameter dimensions, number of germinative pores/pollen grains. The analyses were made during a period of three consecutive years, and the annual values were checked depending on the environment.
Key word: pollen grains, size, germinative pores, polyploidy.
