Improving living standards have led to increasing interest in the quality of watermelon [Citrullus lanatus (Thunb.) Manf.] fruit among producers and consumers; thus, the cultivation of high-quality watermelon varieties that meet consumer demands is particularly important. Watermelon fruit quality includes commodity quality, organoleptic quality, nutritional quality, and more. Organic acid composition and content are thought to play an important role in the organoleptic quality, nutritional quality, and metabolism of the fruit (Silva et al., 2004; Zampini et al., 2008). Furthermore, organic acids have important nutritional value for the human body; the natural flavor malic
