Factors Influencing the Development of Cyanide-resistant Respiration in Potato Tissue.
Ethylene, cyanide gas, and volatalized ethanol, acetaldehyde, and acetic acid were applied in a continuous flow to whole potato tubers. Freshly cut slices were obtained periodically during the treatment, and showed a progressive development of a cyanide-resistant respiration. The application of the employed volatiles in 100% O(2) accelerated the onset and the magnitude of the cyanide-resistant respiration.These results show that, similar to ethylene and cyanide, the application of ethanol, acetaldehyde, or acetic acid can also lead to the development of cyanide-resistant respiration in whole potato tubers, and that this type of respiration is retained in freshly cut slices.
