A fingerprinting strategy based on genetic (simple sequence repeat) and geochemical (multielement and Sr/Sr ratio) analysis was tested to prove the geographical origin of high-quality Italian products "White Asparagus from Bassano del Grappa" and "Green Pistachio from Bronte". Genetic analysis generated many polymorphic alleles and different specific amplified fragments in both agriproducts. In addition, a core set of markers was defined. According to variability within production soils and products, potential candidate elements linking asparagus (Zn, P, Cr, Mg, B, K) and pistachio (Mn, P, Cr, Mg, Ti, B, K, Sc, S) to the production areas were identified. The Sr isotopic signature was an excellent marker when Italian asparagus was compared with literature data for Hungarian and Peruvian asparagus. This work reinforces the use of Sr isotope composition in the soil bioavailable fraction, as assessed by 1mol/L NHNO, to distinguish white asparagus and pistachio originating from different geographical areas.
基于遗传（简单序列重复）和地球化学（多元素及锶/锶比率）分析的指纹识别策略，被用于验证意大利优质产品“格拉帕河畔巴萨诺白芦笋”和“布龙泰绿开心果”的地理来源。遗传分析在这两种农产品中均产生了许多多态性等位基因和不同的特异性扩增片段。此外，还定义了一组核心标记。根据生产土壤和产品中的变异性，确定了将芦笋（锌、磷、铬、镁、硼、钾）和开心果（锰、磷、铬、镁、钛、硼、钾、钪、硫）与产地联系起来的潜在候选元素。当将意大利芦笋与匈牙利和秘鲁芦笋的文献数据进行比较时，锶同位素特征是一个很好的标记。这项工作强化了利用通过1mol/L硝酸铵评估的土壤生物可利用部分中的锶同位素组成，来区分源自不同地理区域的白芦笋和开心果。
