【摘要】 【目的】分析不同产区塞外红苹果果实品质并对其适应性进行评价，为进一步发掘和提高不同产区的塞外红苹果优势品质提供理论依据。【方法】精选2023年辽宁阜蒙县、辽宁辽阳市、辽宁营口市、辽宁铁岭市、新疆阿克苏市、吉林桦甸市、内蒙古通辽市等7个产区的塞外红果实，对其品质指标进行测定分析。【结果】各产区塞外红单果重总体偏小（<60 g）；果实硬度较高，新疆阿克苏塞外红最低可达15.50±1.03 kg/m~2，可溶性固形物含量新疆阿克苏最高，可达（20.78±1.52）%，色差指数以及色泽和光洁度评分新疆阿克苏市相对较低；不同产区塞外红苹果果形指数差别不大，仅新疆阿克苏市对塞外红苹果果实可溶性固形物、酸度、硬度以及色差指数等指标影响较大。【结论】塞外红苹果在北方地区均表现良好，不同产区品质略有差异，但在新疆阿克苏市着色更深，口感更佳。更多还原

【Abstract】 【Objective】Analysis the fruit quality and adaptability of Saiwaihong apple in different areas in the hope of providing a theoretical basis for further exploring and improving the superior quality in different production areas.【Methods】Selected seven main production areas including Fumeng county in Liaoning,Liaoyang city in Liaoning,Yingkou city in Liaoning,Tieling city in Liaoning,Aksu city in Xinjiang,Huadian city in Jilin,and Tongliao city in Inner Mongolia in 2023 to analyze their quality indicators.【Results】The results showed that the average fruit weight was less than 60 g. The fruit hardness was relatively higher,with the lowest value of Xinjiang Aksu reaching 15.50±1.03 kg/m~2,but with the highest content of soluble solids(20.78±1.52)%.The color difference index and smoothness scores of Aksu Prefecture were relatively low. There was no significant difference in the shape index of infrared fruit among different regions,but Saiwaihong apple in Aksu had significant influence on the soluble solid,acidity,hardness and color difference index. Saiwaihong had strong adaptability in the north of China.【Conclusion】Saiwaihong grows well in the northern parts of China,but under the influence of the natural environment of Aksu,the color is darker,and its fruit tastes better.更多还原
