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在学术研究和作物生产中都很有价值。然而，快速准确的鉴定一直很困难，因为许多品种具有非常相似的形态特征，并且易受生长环境的影响。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图谱。由于不同品种的化学成分很大程度上由其基因而非生长环境控制，因此该方法在品种鉴定方面具有相当大的潜力。采集了三个品种的葛根，共十六个地点，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，利用伏安数据可以区分三个品种的电化学图谱。
