摘　　要：【目的】深入挖掘新疆地区的蔷薇果实种质资源,了解其主要营养成分差异,为蔷薇果品质改良及开发利用提供参考依据。【方法】以单叶蔷薇、密刺蔷薇、宽刺蔷薇和弯刺蔷薇等10种新疆蔷薇果为试验材料,测定果实中总糖、可溶性蛋白和酚酸的含量并进行方差分析、相关性分析及聚类分析,运用隶属函数法对10种新疆蔷薇果实进行差异分析和营养品质综合评价。【结果】单叶蔷薇果实的总糖和酚酸含量最高,分别为125.54、9.09 mg·g^(-1),现代月季‘天山祥云’果实的总糖和酚酸含量最低,分别为102.90、4.78 mg·g^(-1);可溶性蛋白含量最高的是‘天山祥云’,为46.68 mg·g^(-1),最低的是宽刺蔷薇,为28.51 mg·g^(-1)。相关性分析表明,蔷薇果的酚酸与总糖含量呈极显著正相关,可溶性蛋白与酚酸和总糖均呈现极显著负相关。聚类分析结果显示,10种新疆蔷薇果可分为3个类群,第1类是弯刺蔷薇、疏花蔷薇1、宽刺蔷薇、托木尔蔷薇和尖刺蔷薇;第2类是单叶蔷薇;第3类包括疏花蔷薇2、‘天山祥云’、密刺蔷薇和伊犁蔷薇,可根据不同需求和目标选择相应的果实类群。平均隶属函数值可排序为:单叶蔷薇>密刺蔷薇>弯刺蔷薇>伊犁蔷薇>托木尔蔷薇>尖刺蔷薇>疏花蔷薇1>宽刺蔷薇>疏花蔷薇2>‘天山祥云’。【结论】蔷薇属果实具有较高的食用价值和药用价值,但不同蔷薇果中总糖、可溶性蛋白和酚酸含量差异较大,该研究结果可为蔷薇属果实的开发利用提供一定的参考依据和理论支撑。【Objective】In order to deeply excavate the rosehip germplasm resources in Xinjiang,investigate variations in key nutritional constituents,and provide a reference basis for the quality improvement and utilization of rosehips.【Method】10 species Xinjiang rosehips,such as Rosa persica,R.spinosissima,R.platyacantha and R.beggeriana,were used as experimental materials.The contents of total sugar,soluble protein and phenolic acid in fruits were determined and analyzed by variance analysis,correlation analysis and cluster analysis.The nutritional quality of 10 species Xinjiang rosehips was comprehensively evaluated by membership function method.【Result】The contents of total sugar and phenolic acid were the highest in R.persica,which were 125.54 mg·g^(-1) and 9.09 mg·g^(-1),respectively.The contents of total sugar and phenolic acid of R.‘Tianshan Xiangyun’were the lowest,which were 102.90 mg·g^(-1) and 4.78 mg·g^(-1),respectively.The highest content of soluble protein was R.‘Tianshan Xiangyun’,which was 46.68 mg·g^(-1),and the lowest was R.platyacantha,which was 28.51 mg·g^(-1).The correlation analysis showed that phenolic acid was significantly positively correlated with total sugar,while soluble protein was negatively correlated with both phenolic acid and total sugar.The cluster analysis showed that 10 species Xinjiang rosehips could be divided into three groups.The first group was R.beggeriana,R.laxa(SH1),R.platyacantha,R.laxa var.tomurensis and R.oxyacantha.The second group was R.persica and the third group included R.laxa(SH2),R.‘Tianshan Xiangyun’,R.spinosissima and R.iliensis.The corresponding fruit groups could be selected according to different needs and goals.According to the average membership function value,it was ordered as follows:R.persica>R.spinosissima>R.beggeriana>R.iliensis>R.laxa var.tomurensis>R.oxyacantha>R.laxa(SH1)>R.platyacantha>R.laxa(SH2)>R.‘Tianshan Xiangyun’.【Conclusion】The contents of total sugar,soluble protein and phenolic acid in different rosehips we
