抄録

Cytomixis is described as an spontaneous phenomenon in <I>L. odoratus</I>. Cytoplasmic channels were seen at all stages of microsporogenesis connecting from few to several meiocytes. Chromatin migration between cells was observed mainly at early prophase, metaphase II and telophase II with decreasing frequencies as meiosis advanced. Cytological analysis revealed other abnormalities in very low frequencies such as alteration of bivalents disjuction, laggards and bridges. Degenerating gametes as well as nonreduced gametes and microgametes were observed, although their frequencies varied depending on anthers and floral buds. Significance of cytomixis in pollen viability and seed set is discussed.
