Polyploid Mitoses, Extranuclear Bodies, and Mitotic Aberrations in Seedlings of Lilium Maximowiczii Regel

In seedlings of Lilium Maximowiczii Regel., polyploid mitoses, Feulgenpositive bodies present in the cytoplasm, and mitotic disturbances were found. The relation between cytoplasmic bodies and mitotic disturbanes was discussed. Both mitotic aberrations and extranuclear bodies were most frequently observed at the start of germination, less frequently at later stage, and have never observed in seedlings about 1.2 cm. in length. One interpretation was given for the origin of extranuclear bodies in somatic cells. The numerical aberration of the chromosomes was found in seedlings of this lily.
