Understanding the metabolic characteristics of pineapple varieties is crucial for market expansion and diversity. This study performed comparative metabolomic analysis on the "Comte de Paris" (BL) and three Taiwan-introduced varieties: "Tainong No. 11" (XS), "Tainong No. 23" (MG), and "Tainong No. 13" (DM). A total of 551 metabolites were identified across the four varieties, with 231 metabolites exhibiting no significant differences between all varieties. This included major sugars such as sucrose, glucose, and fructose, as well as key acids like citric, malic, and quinic acids, indicating that the in-season maturing fruits of different pineapple varieties can all achieve good sugar-acid accumulation under suitable conditions. The differentially accumulated metabolites (DAMs) that were identified among the four varieties all primarily belonged to several major subclasses, including phenolic acids, flavonoids, amino acids and derivatives, and alkaloids, but the preferentially accumulated metabolites in each variety varied greatly. Specifically, branched-chain amino acids (L-leucine, L-isoleucine, and L-valine) and many DAMs in the flavonoid, phenolic acid, lignan, and coumarin categories were most abundant in MG, which might contribute to its distinct and enriched flavor and nutritional value. XS, meanwhile, exhibited a notable accumulation of aromatic amino acids (L-phenylalanine, L-tryptophan), various phenolic acids, and many lignans and coumarins, which may be related to its unique flavor profile. In DM, the dominant accumulation of jasmonic acid might contribute to its greater adaptability to low temperatures during autumn and winter, allowing off-season fruits to maintain good quality. The main cultivar BL exhibited the highest accumulation of L-ascorbic acid and many relatively abundant flavonoids, making it a good choice for antioxidant benefits. These findings offer valuable insights for promoting different varieties and advancing metabolome-based pineapple improvement programs.
了解菠萝品种的代谢特征对于市场拓展和品种多样化至关重要。本研究对“巴黎伯爵”（BL）和三个台湾引进品种：“台农11号”（XS）、“台农23号”（MG）和“台农13号”（DM）进行了比较代谢组学分析。在这四个品种中共鉴定出551种代谢物，其中231种代谢物在所有品种之间无显著差异。这包括主要的糖类，如蔗糖、葡萄糖和果糖，以及关键的酸类，如柠檬酸、苹果酸和奎尼酸，表明不同菠萝品种的季内成熟果实在适宜条件下都能实现良好的糖酸积累。在这四个品种中鉴定出的差异积累代谢物（DAMs）主要属于几个主要亚类，包括酚酸、黄酮类、氨基酸及其衍生物和生物碱，但每个品种中优先积累的代谢物差异很大。具体而言，支链氨基酸（L-亮氨酸、L-异亮氨酸和L-缬氨酸）以及黄酮类、酚酸、木脂素和香豆素类中的许多DAMs在MG中含量最高，这可能有助于其独特而丰富的风味和营养价值。同时，XS表现出芳香族氨基酸（L-苯丙氨酸、L-色氨酸）、各种酚酸以及许多木脂素和香豆素的显著积累，这可能与其独特的风味特征有关。在DM中，茉莉酸的优势积累可能有助于其在秋冬季节对低温具有更强的适应性，使淡季果实保持良好品质。主要品种BL表现出L-抗坏血酸的最高积累以及许多相对丰富的黄酮类，使其成为具有抗氧化益处的良好选择。这些发现为推广不同品种和推进基于代谢组学的菠萝改良计划提供了有价值的见解。
