Mitochondria from whole potatoes (Solanum tuberosum) ordinarily fail to oxidize respiratory substrates and to consume molecular O(2) in the presence of cyanide. Mitochondrial preparations obtained from tubers previously held for 24 hours in ethylene (10 microliters per liter) in air are only partially inhibited by cyanide. Application of ethylene in 100% O(2) led to an additional increase in the resistance of the mitochondrial respiration to cyanide. The resistance to cyanide was accompanied by a decrease in the respiratory control but no change in oxidative phosphorylation as shown by the measurement of ATP synthesis.The development of resistance to cyanide following the application of ethylene appears to require whole tubers and may represent an inductive process.
来自完整马铃薯（茄属块茎）的线粒体在氰化物存在的情况下通常无法氧化呼吸底物和消耗分子氧（O₂）。从先前在空气中用乙烯（10微升/升）处理24小时的块茎中获得的线粒体制剂仅受到氰化物的部分抑制。在100%氧气中施加乙烯导致线粒体呼吸对氰化物的抗性进一步增加。对氰化物的抗性伴随着呼吸控制的降低，但如ATP合成测量所示，氧化磷酸化没有变化。施加乙烯后对氰化物抗性的发展似乎需要完整的块茎，并且可能代表一个诱导过程。
