title: [Cell kinetics and experimental rearrangement of daughter chromosomes at the end of mitotic division].
abstract: The action of hexamethylene-tetramine (HMT), which causes a late disorientation of the two sets of chromosomes during telophase in Allium sativum L. meristematic root cells, has not been found again, in the same material after synchronization by hydroxyurea. The explanation put forward takes into account the special feature of cells synchronized by chemical methods. Besides, the toxicity of HMT is not the same according to the stage of the cell cycle during the treatment.
