During general studies upon DNA metabolism in plants, it was observed that there appeared to be changes involving the inconstancy of the phases of the cell cycle in mitotic populations with increasing age of the plants. To an extent, similar changes were indicated by studies on the actively dividing crypt cells of the mouse duodenum (Lesher, Fry and Kohn, 1961). Hence the plant system was further investigated to determine the extent of the changes and also to see if plant apical meristems might provide a model system for the study of ageing on mitotic cell populations.
