Although considerable work has been done on the respiration of potato tubers most of it has been concerned with internal changes. Some very interesting correlations have been secured but the more recent work, particularly that of Bennet and Bartholomew (8) points to the permeability of the epidermis as the big controlling factor in respiration. It is a commonly accepted fact that the purpose of lenticels is to serve as an aperture through which the gases concerned in respiration may pass. The lenticels of the potato tuber should be no exception. The surface area should also greatly influence respiration since a relatively larger surface is exposed in small potatoes, with a consequently easier access of oxygen to the tissues. Indeed Hoffman (20) has found the surface area to be a limiting factor. The following study was undertaken, with these facts in mind, to determine if a definite correlation exists between the number of lenticels, surface area and the rate of respiration in potato tubers.
