Abstract
The final length of the root cell is the result of a series of prooesses which represent a transition of the growing cell from its origin up to the completion of its elongation. These processes are associated on the one hand with cell proliferation, or, after the termination of proliferation, with the proceeding DNA synthesis, and with cell elongation on the other. The group of properties characterizing the growth region of the root as a cytologically heterogeneous complex, is at the same time the group of causes which affect the length of root cells. The individual cases documented in the paper point out the fact that the mechanisms regulating growth processes, have a locally limited action, often only within one single cell, and that they are simultaneously subordinated to the regulatory mechanism which controls the growth of the root as an entirety.
