Potato tuber tissue respiration & ventilation.

The purpose of this work is to compare gas movement through potato tuber tissue with the respiratory rate of such tissue and to assess possible oxygen deficiency as a factor in the limitation of respiration within the tissue. Argon 37 was used as a substitute for oxygen in most of the gas transfer experiments because it is easier to measure, its solubilities and diffusion coefficients are very similar to those of oxygen in a wide variety of solvents, and its rate of movement can be measured independently of respiration.
