摘　　要：以黑龙江省36份秋子梨果实为试材,采用ICP-MS法对果皮和果肉中12种矿质元素含量进行测定并比较分析。结果表明:秋子梨果实中各矿质元素的平均含量依次为K>P>Ca>Mg>Na>Al>Fe>Zn>Cu>Cr>Pb>Cd,不同种质中果皮和果肉各元素的含量差异明显,野生资源的果实矿质元素含量高于选育品种、农家品种和优良品系。相关性分析结果表明,果皮和果肉中的P、K、Fe、Cu和Zn这5种元素之间存在极显著正相关。聚类分析结果表明,根据果皮或果肉的矿质元素含量,36份秋子梨种质可分为2个略有不同的类别。主成分分析表明,S23、S20、S16和S10是果实矿质元素总含量较高的品种,可优先作为功能性品种选育种质材料,为秋子梨果实矿质元素的遗传改良提供更为深入和有价值的依据。The contents of 12 mineral elements in peel and pulp of 36 Pyrus ussuriensis Maxim.from Heilongjiang Province were determined by ICP-MS method.The results showed that the average content of mineral elements in Pyrus ussuriensis Maxim.fruit was in the order of K>P>Ca>Mg>Na>Al>Fe>Zn>Cu>Cr>Pb>Cd.The contents of elements in skin and flesh of different fruits were significantly different.The content of mineral elements in fruits from wild resources is higher than that of selected varieties,farmer-owned varieties and superior strains.Correlation analysis showed that there was a highly significant positive correlation between the five elements(P,K,Fe,Cu and Zn)in peel and pulp.The results of cluster analysis showed that 36 Pyrus ussuriensis Maxim.could be divided into two slightly different categories according to the content of peel or pulp.Principal component analysis showed that S23,S20,S16 and S10 were cultivars with high total content of mineral elements,which could be preferentially used as germplasm materials for functional varieties breeding in the future,providing more in-depth and valuable basis for genetic improvement of mineral elements of Pyrus ussuriensis Maxim..
