Abstract
The paper describes the phenomenon of disorganization of completely formed subcellular structures: division spindle, phragmoplast and chromosome telophase groups. These structures disintegrate into their elements (cytoskeletal fibers, chromosomes) that transform into chaotic system. Chaotization of cytoskeleton structures such as prophase spindle in mitosis or perinuclear ring in meiosis is a normal step of wild type plant cell division. Disintegration of division spindle and phragmoplast presumably indicate the abnormality of temporal regulation of cytoskeleton cycle during meiosis. Disintegration of telophase chromosome groups and the migration of the chromosomes backward to the equatorial area might mean the abnormal start of some prometaphase mechanisms, in particular, chromokinesins activation.
