The rapid identification of plant variety is valuable in both academic studies and crop production. However, rapid and accurate identification has been difficult because many varieties have very similar morphological characteristics and are susceptible to the effects of the growing environment. In this work, we established an electrochemical method for recording the electro-active profile of compounds in plant tissue. Because the chemical composition of different varieties is largely controlled by their genes, rather than a growing environment, this method has considerable potential for variety identification. Three varieties of Pueraria with sixteen locations were collected for confirming the feasibility of the proposed methodology. Principal component analysis and peak ratio analysis have been used for grouping the sample data. The results indicate the electrochemical profiles of three varieties can be distinguished using their voltammetric data.

植物品种的快速鉴定对于学术研究和作物生产都很有价值。然而，由于许多品种具有非常相似的形态特征并且容易受到生长环境的影响，因此快速准确的鉴定一直很困难。在这项工作中，我们建立了一种电化学方法来记录植物组织中化合物的电活性分布。由于不同品种的化学成分很大程度上受其基因控制，而不是生长环境，因此该方法在品种鉴定方面具有相当大的潜力。收集了 16 个地点的 3 个葛根品种，以确认所提出方法的可行性。主成分分析和峰比分析已用于对样本数据进行分组。结果表明，可以使用伏安数据区分三个品种的电化学特征。
