Abstract：
Melon landraces are highly appreciated by consumers who pay price premiums to compensate for lower yields, enabling on-farm conservation. However, they are highly susceptible to soilborne diseases. This study analyses the impact of Cucurbita and Cucumis rootstocks on the accumulation of flavor-related metabolites in Spanish landraces of the Ibericus melon group, as a strategy to promote their sustainable cultivation. Scion genotype was the main factor conditioning the accumulation of sugars and acids both under standard and saline organic farming conditions. The effects of grafting on organic acid accumulation were negligible, while the effects on sugar content were significant. The latter effects were dependent on specific scion-rootstock combinations, though wild Cucumis (e.g. Fian) rootstocks represent an alternative that should be further studied. The effect on the accumulation of volatiles was limited, and again depended on specific scion-rootstock combinations. The rootstock effect even differed between populations of the same landrace.
摘要：
甜瓜地方品种受到消费者的高度赞赏，他们支付价格溢价以补偿较低的产量，实现农场保护。然而,他们极易受到土壤传播疾病的影响。这项研究分析了葫芦和黄瓜砧木对伊比利亚甜瓜组西班牙地方品种中风味相关代谢产物积累的影响，作为促进其可持续种植的战略。在标准和盐水有机农业条件下，接穗基因型是调节糖和酸积累的主要因素。接枝对有机酸积累的影响可以忽略不计，而对糖含量的影响显著。后者的影响取决于特定的接穗-砧木组合，尽管野生黄瓜（例如Fian）砧木代表了一种应进一步研究的替代方法。对挥发物积累的影响是有限的，再次取决于特定的接穗-砧木组合。同一地方品种的种群之间的砧木效应甚至不同。
