Abstract
Low oxygen and/or high carbon dioxide significantly suppressed respiration, yellowing and decay of Chinese chives. Especially the combination of low oxygen and high carbon dioxide was more effective compared to the each treatment alone, On the other hand, although Chinese chives did not produce detectable ethylene, ethylene treatment accelarated moderately respiration according to the concentration and slightly enhanced yellowing and decay of leaves. Treatment with 2, 5-norbornadiene, known as inhibitor for ethylene action, suppressed respiration and dacay. However the inhibition of yellowing was weaker than that of other crops known, It implied that ethylene might not act direct role for yellowing of Chinese chives, although the compound affect dacay of the leaves at the end of storage.
