| 中文摘要: |
| 为探究采后套袋对‘昔卜柑’( Citrus reticulata Blanco. cv. Xibu Gan)果实品质和贮藏性的影响,将果实在自然通风条件下贮藏80 d,以不套袋处理为对照(CK),每10 d检测一次,分析不同处理下果实的可溶性固形物、可滴定酸、可溶性糖、有机酸、Vc、异味物质(甲醇、乙醇、乙醛等)含量以及硬度、呼吸强度等的变化规律。结果表明,套袋处理可减缓整个贮藏期果实Vc和酸含量的下降速度，避免贮藏后期（50～80 d）果皮变硬，降低整个贮藏期果实失重率和腐烂率，抑制贮藏中后期(30～80 d)果实呼吸强度，降低异味物质含量，使异味物质峰值延后10 d左右。因此采后套袋可延缓贮藏期‘昔卜柑’果实细胞衰老,维持果实口感和商品性,延长贮藏时间。生产上建议种植户采收后进行单果套袋,放置于常温通风库贮藏,贮藏时间最好不超过80 d。本试验可为‘昔卜柑’采后贮藏保鲜技术的应用提供参考依据。 |
| 英文摘要: |
| To investigate the effects of postharvest bagging on fruit quality and storability of "Xibu Gan" (Citrus reticulata Blanco. cv. Xibu Gan), fruits were stored under natural convection conditions for 80 days. Using non-bagged fruit as the control (CK), sampling and analyses were conducted at 10-day intervals to determine the changes in soluble solids content (SSC), titratable acidity (TA), soluble sugars, organic acids, vitamin C (Vc) content, concentrations of off-flavor compounds (methanol, ethanol, acetaldehyde), firmness, and respiration rate under different treatments. The results demonstrated that the bagging treatment slowed down the decline rate of vitamin C and acid content in fruits during the entire storage period, prevented the hardening of the peel in the later storage stage (50-80 days), reduced the fruit weight loss rate and decay incidence rate throughout storage, suppressed fruit respiration rate during the mid-to-late storage period (30–80 d), reduced the total concentration of off-flavor compounds, delaying their peak occurrence by approximately 10 days. Consequently, postharvest bagging retards cellular senescence, preserves fruit quality and marketability, and extends the potential storage duration. For practical application, it is recommended that growers adopt individual fruit bagging postharvest, followed by storage in ambient-temperature ventilated facilities, with the storage duration not exceeding 80 days. This study serves as a reference basis for applying postharvest storage and preservation technologies to "Xibu Gan". |
