| 中文摘要: |
| 为研究不同采收期对蓝莓贮藏品质及生理代谢的影响，以‘绿宝石’蓝莓为试验材料，测定不 同采收期蓝莓果实在贮藏过程中品质指标、抗氧化酶活性及花色苷代谢的变化。结果表明，与坐果 70 d相比，坐果60 d采收能够更好地维持蓝莓在贮藏期间的果实硬度，并有效延缓失重率和烂果率的 上升。在贮藏过程中，坐果60 d采收有利于蓝莓维持较高的抗氧化酶活性，并促进抗氧化物质的积 累。此外，坐果60 d采收可提高蓝莓在贮藏期间花色苷的积累，并在贮藏后期减缓花色苷的降解进 程。研究结果可为蓝莓适宜采收期的选择及采后贮藏保鲜技术提供理论依据。 |

| To investigate the effects of different harvest dates on the storage quality and physiological metabolism of blueberries, ‘Emerald’ blueberries were used as experimental materials, and changes in fruit quality indicators, anti? oxidant enzyme activities, and anthocyanin metabolism of blueberry fruits harvested at different times were measured during storage. The results showed that, compared with harvesting at 70 days after fruit set, harvesting at 60 days after fruit set better maintained fruit firmness during storage and effectively delayed the increases in weight loss rate and decay rate. During storage, harvesting at 60 days after fruit set favored the maintenance of higher antioxidant enzyme activities and promoted the accumulation of antioxidant substances. In addition, harvesting at 60 days after fruit set could enhance anthocyanin accumulation in blueberries during storage and slowed down the degradation process of anthocyanins at the later stage of storage. These findings can provide a theoretical basis for selecting the appropriate harvest date and developing postharvest storage and preservation techniques for blueberries. |
