【摘要】 明确不同产区南果梨果实品质，为南果梨资源的合理和高效利用提供数据参考，同时也为梨优良栽培品种的选育提供借鉴。以鞍山市8个产区南果梨果实为研究对象，利用电感耦合等离子体-原子发射光谱（ICP-AES）测定南果梨果实17种矿物质元素含量，采用离子色谱仪测定4种可溶性糖含量，通过液相色谱仪测定5种有机酸含量。结果表明：8个产区南果梨果实矿物质元素含量均以磷、钾、钙和镁含量较高，占总元素含量的97%以上，镍、钒、钴、锶、钯和银含量较低，但不同产区南果梨果实矿物质元素含量排序不同；8个产区南果梨果实4种可溶性糖平均含量排序为果糖>葡萄糖>蔗糖>山梨醇，5种有机酸平均含量排序为柠檬酸>苹果酸>奎尼酸>莽草酸>富马酸。鞍山地区8个产区南果梨果实品质指标含量上有差异，但矿物质元素均以磷、钾、钙和镁为主，可溶性糖含量和有机酸含量均以果糖、葡萄糖、柠檬酸和苹果酸较高。更多还原

【Abstract】 In order to clarify the fruit quality of the main planting area of ’Nanguo’ pear, provide data reference for the rational and efficient utilization of ’Nanguo’ pear resources, and also provide reference for the cultivation of excellent pear varieties, eight ’Nanguo’ pear regions in Anshan were selected as the research objects. The contents of 17 mineral elements in ’Nanguo’ pear were determined by inductively coupled plasma-atomic emission spectrometry(ICP-AES), the contents of4 kinds of soluble sugars were determined by ion chromatograph, and the contents of 5 kinds of organic acids were determined by liquid chromatograph. The results showed that P, K, Ca and Mg contents were the highest in ’Nanguo’ pear in the 8 regions, accounting for more than 97% of the total elements, while Ni, V, Co, Sr, Pd and Ag contents were lower.However, the order of mineral elements contents was different in ’Nanguo’ pear fruits from different regions. The average content of 4 kinds of soluble sugars in the 8 regions was ranked as fructose > glucose > sucrose > sorbitol. The average content of 5 kinds of organic acids was ranked as citric acid > malic acid > guanic acid > shikimic acid > fumaric acid. There were differences in the content of quality indexes in the 8 regions of ’Nanguo’ pear, but all of them followed the principle that the mineral elements were mainly P, K, Ca and Mg, the contents of soluble sugars and organic acids were the highest in fructose, glucose, citric acid and malic acid.更多还原
