| 目的 探究不同采收期对1–MCP处理后蓝靛果在0~75 d期间品质的影响，为蓝靛果长期贮存的最佳采收期提供参考。方法 以2个采收期(采收期Ⅰ:果实开花后45 d;采收期Ⅱ:果实开花后50 d)的蓝靛果为实验材料，在采后用1–甲基环丙烯(1-Methylcyclopropene，1-MCP)进行处理后装入保鲜箱，在(−0.5±0.3)℃下贮藏75 d，每隔15 d取样测定感官、营养以及生理指标。结果 与采收期Ⅱ组相比，采收期Ⅰ组更能较好地保持果实硬度，降低果实腐烂发霉、流汁、果霜减少的现象。在贮藏75 d时采收期Ⅰ组果实呼吸强度为202.79 mg/(kg.h)，乙烯生成速率为23.27 μL/(kg.h)，分别比采收期Ⅱ组降低了4.90%和10.08%，同时可抑制丙二醛含量的积累以及相对电导率的上升，并在贮藏末期可显著保持抗坏血酸、花色苷、总酚及可溶性蛋白等营养品质(P＜0.05)。结论 采收期Ⅰ组(果实开花后45 d)的蓝靛果用于长期贮藏可以保持较好的外观和内在品质。 |

| The work aims to explore the effects of different harvest periods on the quality of Lonicera caerulea L. after 1-MCP treatment during 0~75 d, so as to provide a reference for the optimal harvest period of Lonicera caerulea L for long-term storage. Lonicera caerulea L. of two harvest periods (harvest period I:45 d after fruit flowering; harvest period II:50 d after fruit flowering) was used as the experimental materials. After treated with 1-methylcyclopropene (1-MCP), the Lonicera caerulea L. was put into a crisper box and stored at (−0.5±0.3) °C for 75 days and then sampled every 15 days to measure organoleptic, nutritional and physiological indicators. Compared with the harvest period II. group, the harvest period I. group was better to maintain the fruit hardness, reducing the phenomenon of fruit rot and mildew, juice and fruit frost. After storage of 75 d, the respiration intensity of the fruit in the harvest period I. group was 202.79 mg/(kg.h) and the ethylene formation rate was 23.27 μL/(kg.h),4.90% and 10.08% lower than those in the harvest period II. group, respectively. The he accumulation of malondialdehyde content and the increase of relative conductivity could be inhibited. At the end of storage, the nutritional qualities of ascorbic acid, anthocyanins, total phenols and soluble protein (P<0.05) were significantly maintained. Lonicera caerulea L. from harvest period I. group (45 d after fruit flowering) can maintain good appearance and intrinsic quality after long-term storage. |
