Abstract

Ethanol, acetaldehyde, and acetic acid, when applied in a volatile state in air to potato tubers, led to a climacteric-like upsurge in respiration. The respiratory upsurge was markedly enhanced when the volatiles were applied in 100% O(2).Ethanol induced a decline in the level of 2-phosphoglyceric acid and phosphoenolpyruvate while leading to the accumulation of tricarboxylic acid cycle intermediates including isocitrate and alpha-ketoglutarate. The action of these compounds was similar to, but independent of, the action of ethylene.

摘要

乙醇、乙醛和乙酸在空气中以挥发状态应用于土豆块茎时,导致呼吸出现类似呼吸跃变的急剧上升。当挥发物在 100% O(2)中应用时,呼吸跃变明显增强。乙醇诱导 2-磷酸甘油酸和磷酸烯醇丙酮酸水平下降,同时导致三羧酸循环中间产物包括异柠檬酸和α-酮戊二酸积累。这些化合物的作用类似于但独立于乙烯的作用。
