There are several species of passion fruit grown in South America. However, there is a lack of information about the mineral content in their pulp. Thus, the objective of the present research was to determine the mineral content in the pulp of different germplasms of passion fruit [ f. (INIAP 2009 and P10), (Sweet passion fruit), f. (Gulupa) and sp. (Criollo POR1 and Criollo PICH1)] grown in Ecuador and to determine their relationship with relevant fruit quality traits. The results showed that high Mg content was associated with less peel thickness, soluble solids was negatively related to K and B content, and vitamin C was negatively related to S content. INIAP 2009 had high titratable acidity and fruit weight but low N and Na; P10 showed the highest contents of N, K, Na, Mn and fruit weight but less P, Mg, and Fe; sweet passion fruit showed high S, Zn, Cu, soluble solids, and peel thickness but low K, Ca, B, and titratable acidity; Gulupa had high Mg, B, and Zn but low S, Fe, and Mn; Criollo POR1 showed high N and Fe but low Zn; and Criollo PICH1 showed high P, Ca, Mg, and Cu but low soluble solids and peel thickness. These results provide additional information on passion fruit germplasm grown in Ecuador and constitutes a reference for further breeding programs.
南美洲种植有几种百香果。然而，关于其果肉中矿物质含量的信息却很匮乏。因此，本研究的目的是测定在厄瓜多尔种植的不同百香果种质[ （INIAP 2009和P10）、 （甜百香果）、 （古鲁帕）和 种（克里奥洛POR1和克里奥洛PICH1）]果肉中的矿物质含量，并确定它们与相关果实品质性状的关系。结果表明，高镁含量与较薄的果皮厚度相关，可溶性固形物与钾和硼含量呈负相关，维生素C与硫含量呈负相关。INIAP 2009的可滴定酸度和果实重量较高，但氮和钠含量较低；P10的氮、钾、钠、锰含量和果实重量最高，但磷、镁和铁含量较低；甜百香果的硫、锌、铜、可溶性固形物和果皮厚度较高，但钾、钙、硼和可滴定酸度较低；古鲁帕的镁、硼和锌含量较高，但硫、铁和锰含量较低；克里奥洛POR1的氮和铁含量较高，但锌含量较低；克里奥洛PICH1的磷、钙、镁和铜含量较高，但可溶性固形物和果皮厚度较低。这些结果为厄瓜多尔种植的百香果种质提供了更多信息，并为进一步的育种计划提供了参考。
