Abstract:

【Objective】 This study was aim to ascertain the effect on the Hami melon pulp softening and cell wall degradation enzymes with vibration stress during storage. 【Method】 The experiment used the thick-skinned muskmelon Xizhoumi 17 as test material，According to GB/T4857.7-2005 standard，using the low-frequency vibration test bench to carry out the fixed-frequency vibration test on hami melon stacking. Comparing the changes of maximum pressure，pulp hardness and cell wall degrading enzyme between vibration stress and none vibration stress. 【Result】 During the post-harvest storage period at room temperature，the maximum pressure and flesh hardness of 'Xizhoumi 17' Hami melon showed a trend of gradual decline，PG activity，CEL activity and PE activity showed a trend of first increase and then decrease，and β-Gal activity showed a trend of gradual increase. 【Conclusion】 Vibration stress could significantly reduce the maximum pressure and flesh hardness of fruit.In terms of impact on the cell wall degradation enzymes，vibration stress can significantly improve the level of activity expression of pulp CEL，15 days before storage，vibration stress can significantly improve the level of pulp PE activity，the expression，the storage effect is not obvious in the late，late vibration stress can significantly improve the storage pulp PG activity expression level，the vibration stress on pulp β-GAL activity effect is not obvious.

摘要：

【目的】 研究采后物流运输振动对哈密瓜贮藏期果肉软化和细胞壁降解酶的影响。【方法】 以厚皮甜瓜西州密17号为试材，采用低频振动试验台，按照GB/T4857.7-2005标准进行哈密瓜堆码定频振动试验，比较经过振动胁迫与没有振动胁迫的哈密瓜在贮藏期果实达到破裂点所能承受的最大压力、果肉硬度和细胞壁降解酶的变化。【结果】 西州密17号哈密瓜采后常温贮藏期内，果实承受最大压力和果肉硬度呈逐渐下降的变化趋势，PG活性、CEL活性、PE活性均呈先升高后降低的变化趋势，β-GAL活性呈逐渐升高的变化趋势。【结论】 振动胁迫可显著降低果实的最大压力和果肉硬度。振动胁迫可显著提高果肉CEL活性表达水平，在贮藏前15 d，振动胁迫可显著提高果肉PE活性表达水平，对贮藏后期的影响不明显，振动胁迫可显著提高贮藏后期果肉PG活性表达水平，振动胁迫对果肉β-GAL活性影响不明显。
