Norwegian fruit production is mostly destined for the local market and can suffer from poor-quality retention during storage. 1-Methylcyclopropene (1-MCP) is an inhibitor of ethylene perception used to maintain the physical and functional quality of pome fruit. Extensive work has been carried out on the effect of 1-MCP on apples, but not on cultivars grown in Norway. In this work, the potential of 1-MCP application (0.625 ml l −1 for 24 h at 0 ± 1℃) for ripening control of the apple cultivars ‘Aroma’, ‘Red Gravenstein’, and ‘Summered’ was studied during 1 and 1.5 months of cold storage; both scenarios were followed by five days of shelf life. The application of 1-MCP reduced softening by an average of 12% in ‘Aroma’, ‘Red Gravenstein’, and ‘Summered’ apples when cold stored for both 1 and 1.5 months as compared to control. External colour remained similar to initial values in 1-MCP fruit when compared to control apples, which presented a significant skin darkening. This indicated a delay in the ripening process. 1-MCP treatment did not affect total soluble solids content. ‘Aroma’ samples treated with 1-MCP showed a low sucrose hydrolysis, indicating a slower ripening process. This work confirms that 1-MCP postharvest treatment shows great potential for maintenance of apple cvs. in Norway during cold storage and shelf life.

1-甲基环丙烯可保持挪威苹果果实的采后品质

挪威的水果生产主要销往当地市场，在储存过程中可能会出现质量差的问题。1-甲基环丙烯 (1-MCP) 是一种乙烯感知抑制剂，用于维持梨果的物理和功能品质。已经对 1-MCP 对苹果的影响进行了广泛的研究，但没有对挪威种植的品种进行研究。在这项工作中，研究了 1-MCP 应用（0.625 ml l -1 在 0 ± 1°C 下 24 小时）对苹果品种 'Aroma'、'Red Gravenstein' 和 'Summered' 的成熟控制的潜力。和1.5个月的冷藏；两种情况后都有五天的保质期。与对照相比，在冷藏 1 个月和 1.5 个月后，使用 1-MCP 可使“Aroma”、“Red Gravenstein”和“Summered”苹果的软化平均降低 12%。与对照苹果相比，1-MCP 水果的外部颜色与初始值保持相似，后者呈现出明显的皮肤变黑。这表明成熟过程的延迟。1-MCP 处理不影响总可溶性固形物含量。用 1-MCP 处理的“香气”样品显示出低蔗糖水解，表明成熟过程较慢。这项工作证实了 1-MCP 采后处理显示出维持苹果 cvs 的巨大潜力。在冷藏和保质期内在挪威。这项工作证实了 1-MCP 采后处理显示出维持苹果 cvs 的巨大潜力。在冷藏和保质期内在挪威。这项工作证实了 1-MCP 采后处理显示出维持苹果 cvs 的巨大潜力。在冷藏和保质期内在挪威。
