Abstract: The regularity of the presence of plasmodesmata channels in the pollen mother cells of lily was studied by transmission and scanning electron microscopy. A few plasmodesmata channels can be recognized between the pollen mother cells at leptotene stage, which increase in number at zygotene and expand in width at synizesis and they lie in the range 0.5—1 μm. Massive chromatin substance are transferred from one pollen mother cell to another during synizesis. The pre-existing plasmodesmate channels close again at late pachytene. There are no channels from metaphase Ⅰ to tetrad stage. Finally, the relation between the presence of plasmodesmata channels, synizesis and cytomixis were discussed.
Key words: Lilium davidil var. willomottiae, Plasmodesmata chanuels
