通过实验研究了噪声对黄瓜贮藏的影响。选用频率为 2～ 4kHz,强度分别为 85、95和 1 0 2dB的噪声 ,测定采摘后黄瓜在 8～ 1 2d的贮藏时间内 ,过氧化氢酶 (CAT)活性的变化趋势及 85dB噪声作用下其内源乙烯释放量的变化。结果表明 ,噪声能提高采后黄瓜内源乙烯的释放量 ,使黄瓜的CAT活性在贮藏前期维持在较高水平 ,贮藏后期下降速度较快 ,黄瓜较早失去食用价值。即噪声加速采摘后黄瓜的衰老 The effect of noise on the storage of cucumber was experimentally studied. The frequency of 2 ~ 4kHz and the intensity of 85, 95 and 102dB were used respectively to measure the change trend of catalase (CAT) activity and the effect of 85dB noise during the storage period of 8 ~ 12d Its endogenous ethylene release changes. The results showed that noise could increase the release of endogenous ethylene in postharvest cucumbers, and maintain the CAT activity of cucumbers at a relatively high level in the early stage of storage. However, the cucumber decreased rapidly in the late storage period, and cucumber lost its food value earlier. That is, the noise accelerates the cucumber’s aging after picking
