摘　　要：【目的】通过对陕北地区24个酸枣种仁的核心品质指标进行分析,鉴定及筛选具有高价值的酸枣仁种质资源。【方法】以陕北黄河沿岸7个种源地24个酸枣种仁为研究对象,基于不同种源酸枣表观性状与酸枣仁功能成分,利用变异系数分析、相关性分析、聚类分析,以及概率分级、主成分分析等方法,对不同产地酸枣仁品质进行综合评价。【结果】陕北酸枣不同种源酸枣性状存在较大差异,其中,双仁率的变异系数最大(54.61%),果形指数的变异系数最小(10.16%)。通过主成分分析综合评价,山东、吴堡和延川的得分最高。山东种源的酸枣果实较大,吴堡种源功能成分含量较高,种仁较大。【结论】通过对陕北黄河沿岸7个酸枣种源的表型性状及酸枣仁功能成分分析,明确了陕北酸枣种源多为小果型、仁用型酸枣,研究结果为陕北酸枣优良种质资源的挖掘、酸枣仁质量评价及产品开发提供了数据支撑。【Objective】Sour jujube is a wild type of cultivated sour jujube with a long history and has attracted much attention due to its high value of traditional Chinese medicine.As one of the main pro-duction areas of sour jujube,northern Shaanxi has rich sour jujube germplasm resources.The quality of sour jujube is not only related to genetic background,but also affected by the place of origin and envi-ronment,showing different characteristics of the place of origin.There are geographical differences in the quality of sour jujube fruit,the appearance of the core and the functional components of sour jujube kernel.The evaluation and screening of sour jujube genetic resources in northern Shaanxi have positive significance for promoting the sustainable development of the sour jujube industry.The study aimed to comprehensively analyze the quality of sour jujube kernels from different production areas in northern Shaanxi,so as to accurately screen out sour jujube genetic resources of different quality types,thereby providing a scientific basis for the development and utilization of sour jujube genetic resources.【Meth-ods】In the study,24 types of wild sour jujube kernels were selected from seven production areas along the Yellow River in northern Shaanxi as the research objects.The apparent traits and functional compo-nents of wild sour jujube kernels were comprehensively evaluated by using diversity analysis methods,such as coefficient of variation analysis,correlation analysis and cluster analysis,combined with com-prehensive evaluation methods,like probability classification and principal component analysis.【Re-sults】Analysis of the phenotypic characteristics of Ziziphus jujuba var.spinosa kernels from different provenances showed that the wild jujube kernels from Hebei had the largest weight and were signifi-cantly higher than those from other provenances,and the kernels from Shandong provenance had the largest longitudinal diameter(7.30 mm)and transverse diameter(5.36 mm).The longitudinal diameter(5.24 mm)an
