Abstract: In order to study the effect of vibration on storage quality of Hami melons (Cucumis melo var. saccharinus) in different grades of road during storage, the effect of semi-trailer on highway, arterial roads (ARs), secondary roads (SRs), and tertiary roads (TRs) were simulated, and the hardness, water-soluble pectin content, CDTA-soluble pectin content, sodium carbonated-soluble pectin content, polygalacturonase (PG) activity and pectin esterase (PE) activity of Hami melons in different road vibration treatments during storage at room temperature (23 ℃) were compared. The results showed that the hardness, pectin substance and activity of enzymes related to pectin degradation of Hami melon were lower than those of the control group at 28 days after storage, while water-soluble pectin content, PG and PE activities were higher than those of the control group, and the influence of the TRs, the SRs and ARs on the cell wall of Hami melon was more significant, which indicated that vibration accelerated the degradation of pectin during storage and physiological softening of Hami melon, destructed the integrity of cell wall, and ultimately accelerated the aging of melon.
