Abstract

Changes in the frequency of univalents with increasing developmental age in pollen mother cells of triploid Allium triquetrum were studied. Univalent frequencies were compared in material grown in different places, in first and second inflorescences from plants grown in the same place, and in first inflorescences collected in different seasons. No variation in univalent frequencies (total, equatorial, and polar) was found with increasing developmental age. There were also no changes in the different dyad frequencies at anaphase I with increasing developmental age of the pollen mother cells.
