The knowledge of a chemistry relationship between the soil and the agricultural products is an important tool for the quality assessment of food. We studied YLOID (Y, La and lanthanoids), recognized as very useful tracers due their coherent and predictable behavior, to trace and evaluate their distribution from soil to the grape in Vitis vinifera L. Because much of the world's viticulture is based on grafting, and rootstocks have proved affect vine growth, yield, fruit and wine quality, we carried out experimental trials to analyse the YLOID distribution of two different red cultivars, grafted onto six different rootstocks, on the same soil. The YLOID amounts, the relationship Heavy vs Light YLOID and the pattern of YLOID were calculated. The results showed that the different grafting combinations were not able to induce significant differences in YLOID uptake from the soil maintaining the same fingerprint (with the exception of Eu).
土壤与农产品之间化学关系的知识是食品质量评估的重要工具。我们研究了钇镧系元素（Y、La和镧系元素），因其行为连贯且可预测而被视为非常有用的示踪剂，以追踪和评估它们在酿酒葡萄中从土壤到葡萄的分布。由于世界上大部分葡萄栽培都基于嫁接，且已证明砧木会影响葡萄藤的生长、产量、果实和葡萄酒质量，我们进行了试验，分析了在同一土壤上嫁接到六种不同砧木上的两个不同红色品种的钇镧系元素分布。计算了钇镧系元素的含量、重钇镧系元素与轻钇镧系元素的关系以及钇镧系元素的模式。结果表明，不同的嫁接组合在保持相同指纹（除铕外）的情况下，无法在从土壤中吸收钇镧系元素方面诱导出显著差异。
