A continuous application of ethylene (10 mul/l) and propylene (500 mul/l) to potato tubers (Solanum tuberosum L.) resulted in an upsurge of respiration and a concomitant rise in peroxides. When applied in 100% O(2), the effect of ethylene and propylene on respiration and peroxide formation was augmented. Hydrogen cyanide (500 mul/l) mimicked the action of ethylene and propylene inducing a respiratory rise and a corresponding increase in peroxides. As with ethylene, the effect of HCN was augmented in high O(2) tensions. The results support the suggestion that ethylene activates the cyanide-insensitive respiratory pathway.
对马铃薯块茎(茄属马铃薯)持续施加乙烯(10微升/升)和丙烯(500微升/升)会导致呼吸作用增强,同时过氧化物含量上升。当在100%氧气中施加时,乙烯和丙烯对呼吸作用及过氧化物形成的影响会增强。氰化氢(500微升/升)模拟了乙烯和丙烯的作用,诱导呼吸作用增强以及过氧化物相应增加。与乙烯一样,在高氧张力下氰化氢的作用会增强。这些结果支持了乙烯激活对氰化物不敏感的呼吸途径这一观点。
