Analytic studies in plan respiration. V.—The relation of the respiration of potatoes to the concentration of sugars and to the accumulation of a depressant at low temperatures. Part II.—The form of the normal respiration/sugar relation and the mechanism of depression

Abstract

In Part I of this communication we presented a preliminary stage of the analysis of the interwoven effects of sugar concentration and “low temperature depression” in determining the rate of respiration. In this Second Part we have to begin by investigating the conditions that govern the development of depression and then to apply this closer characterisation to the observed facts already set out in Part I. This will involve a good deal of cross-reference and to avoid confusion the sections, experiments, tables and figures of the present Part are numbered as a continuation of the series in Part I. § 3. The Progress and Magnitude of Depression . We may recall our view of the nature of the depression process, given in the Introduction, as the bulk of the evidence in support of it will be set out in this section.
