摘要

Year-round demand for fresh-cut produce, such as muskmelon (Cucumis melo L. Reticulatus group) fruit, can include importation of whole-fruit from as far away as Chile, requiring expensive air shipments. Surface shipments would reduce these transportation expenses but would also require a longer shelf-life fruit than what is now commercially available to withstand the shipping/storage time frame of up to 5 weeks prior to fresh-cut processing. Current muskmelon cultivars have a fruit storage life of up to 2 weeks. In this 2-year study, we compared the marketable quality and phytonutrient attributes of a novel hybrid with its muskmelon parental lines (ultra-firm femalexcommercial muskmelon cultivar type male) up to 5 weeks at 1 or 5 degrees C. At harvest whole hybrid fruit were larger (33-37% heavier) than its parental lines, and had an external firmness equal to its female parent. The external and internal firmnesses of the female parent were on average 4.5-fold and 3.6-fold firmer, respectively, than those of the male parent. Compared to its male parent, the internal tissue of hybrid fruit was relatively sweeter, more intensly orange, had a higher concentration of beta-carotene, had a seven-fold higher concentration of 5-methyltetrahydrofolate (folic acid), had fewer internal disorders, and reduced senescence. The aforemetioned tissue firmness of hybrid fruit would make it highly suitable to withstand surface shipments of up to 5 weeks; and the aforementioned quality characteristics would make it likely preferable to consumers both taste-wise and nutritionally as a fresh-cut product.

Reticulatus集团）水果，可能包括从智利到远处的全果进口，这需要昂贵的空运。水陆运输将减少这些运输费用，但还需要比目前市售的水果更长的保质期，以承受鲜切加工之前长达5周的运输/存储时间框架。当前的甜瓜品种的果实储存寿命长达2周。在这项为期2年的研究中，我们比较了新型杂种及其甜瓜亲本品系（雄性雌性商业甜瓜栽培品种男性）在1或5摄氏度下长达5周的适销质量和植物营养素属性。收获整个杂种果实比其父母本系更大（重33-37％），并且外部坚挺度与其母本相同。女性父母的外部和内部牢固度分别平均比男性父母强4.5倍和3.6倍。与雄性亲本相比，杂种果实的内部组织相对更甜，橙色更浓，β-胡萝卜素的浓度更高，5-甲基四氢叶酸（叶酸）的浓度高7倍，内部疾病更少，并减少衰老。杂果的上述组织牢固性使其非常适合承受长达5周的表面运输;并且上述质量特性将使消费者在口味上和营养上都可以作为鲜切产品。保留所有权利，Elsevier。
