Two morphologically different cultivars of Italian melons (Baggio and Giusto) were characterized considering samples harvested in different times, at the beginning (BPP) and at the end of the physiological plant production period (EPP). Proximate composition, protein, minerals, pH, phenolic content, antioxidant capacity, ascorbic acid, carotenoids, condensed tannins, and flavonoids were measured, showing a significant decrease in EPP samples (phenolics, antioxidant capacity, condensed tannins, and flavonoids); ascorbic acid decreased in Giusto cv, carotenoids in Baggio cv. Mineral content increased in either the cultivars (EPP samples). Year-to-year difference was significantly highlighted; the plant growing cycle significantly affected the chemotype. Despite these effects, the Principal Component Analysis (PCA) permitted the discrimination of Baggio from Giusto cv, and the discrimination of BPP from EPP samples as well.
两种形态不同的意大利瓜（Baggio 和 Giusto）品种特征明显，考虑到在不同时间收获的样本，在生理植物生产期的开始（BPP）和结束（EPP）。测量了近程成分、蛋白质、矿物质、pH 值、酚类含量、抗氧化能力、抗坏血酸、类胡萝卜素、缩合单宁和类黄酮，结果表明 EPP 样本中的这些物质显著减少（酚类、抗氧化能力、缩合单宁和类黄酮）；Giusto 品种中的抗坏血酸减少，Baggio 品种中的类胡萝卜素减少。两种品种的矿物质含量都有所增加（EPP 样本）。年际差异明显；植物生长周期对化学型有显著影响。尽管存在这些影响，但主成分分析（PCA）允许区分 Baggio 和 Giusto 品种，以及区分 BPP 和 EPP 样本。
