Abstract:
Atypical cell walls and nuclei were observed in the apex of Norway spruce shoots from late April to early May on the material collected from a few grafts of a clone of Norway spruce growing on an experimental area. Images of ultrastructure attest to cytomixis. The phenomenon of cytomixis has previously been described in various plant material, both in the meiotic and mitotic cells, but this is the first report of cytomixis in gymnosperms.
