To explore the effects of high voltage electrostatic field treatment on the storage quality and postharvest physiology of Pyrus ‘Yu Lu Xiang’.
Using Pyrus ‘Yu Lu Xiang’s as material, experiments were conducted under conditions of 24 °C and 85%–90% relative humidity. The 3 electric field intensities (50, 100 and 150 kV/m) were applied, with treatment durations of 1, 2 and 3 h, respectively, followed by storage for 45 d. A control group received no treatment. Indicators including fruit firmness, soluble solid content, color difference,respiration rate and ethylene release were measured on 9, 18, 27, 36 and 45 d of storage.
The 100 kV/m treatment was most effective in maintaining fruit firmness and soluble solid content. The 50 kV/m treatment was most effective in suppressing the respiration rate and ethylene release. The treatment at 100 kV/m for 1 h effectively delayed the quality deterioration of Pyrus ‘Yu Lu Xiang’s and extended their storage period.
In summary, high voltage electrostatic field treatment can effectively maintain the storage quality of Pyrus ‘Yu Lu Xiang’. This study provides a practical and feasible protocol for the preservation and storage of Pyrus‘Yu Lu Xiang’.
