| 摘 要： | 通过对不同淮山药品种(种质)的营养成分进行测定，并对结果进行相关与聚类分析，结果表明，蛋白质含量最高的是桂淮5号和GY2，分别为3.03%和2.69%;淀粉和总氨基酸含量最高的是GY2和GY62，分别为2976%、1.95%和27.9%、1.88%;总皂甙含量最高的是GY2和GY47，铁、锌、铜含量最高的是GY2.因此，GY2的综合营养品质较好.相关分析结果显示，不同营养品质成分之间具有相互促进关系:淀粉与总皂甙含量呈极显著正相关，脂肪与锌含量呈极显著正相关，可溶性总糖与锌、铁、铜含量均呈极显著正相关.通过聚类分析，可将不同淮山药品种(种质)分为总皂甙含量较高型、铁含量较高型、淀粉含量较高型、蛋白质氨基酸含量较高型等4大类，营养品质差异也可作为淮山药种质分类的依据之一. |
