Abstract：
Electrochemical fingerprinting can collect the electrochemical behavior of electrochemically active molecules in plant tissues, so it is regarded as a new plant analysis technology. Because the signal of electrochemical fingerprinting is positively correlated with the amount and type of electrochemically active molecules in plant tissues, it can also be used to reflect genetic differences between different species. Previous electrochemical fingerprinting techniques have been frequently used in phylogenetic studies of herbaceous plants. In this work, 19 Quercus species (17 evergreen or semi evergreen species and 2 deciduous species) were selected for investigation. The results indicated the electrochemical fingerprint of some species share similar features but can be distinguished after changing the recording condition (extraction solvent and electrolyte). The two sets of electrochemical fingerprint data can be used to construct different pattern recognition technology, which further speeds up the recognition efficiency. These electrochemical fingerprints were further used in phylogenetic investigations. The phylogenetic results deduced from electrochemical fingerprinting were divided mainly into three clusters. These can provide evidence for some of these arguments as well as new results.
摘要：
电化学指纹图谱可以采集植物组织中电化学活性分子的电化学行为,因此它被认为是一种新的植物分析技术。由于电化学指纹的信号与植物组织中电化学活性分子的数量和类型呈正相关,它也可以用来反映不同物种之间的遗传差异。先前的电化学指纹技术已经常用于草本植物的系统发育研究。在这项工作中,选择19种（常绿或半常绿17种，落叶2种）进行调查。结果表明，某些物种的电化学指纹具有相似的特征，但可以在改变记录条件（萃取溶剂和电解质）后进行区分。两组电化学指纹数据可用于构建不同的模式识别技术，这进一步加快了识别效率。这些电化学指纹进一步用于系统发育研究。从电化学指纹图谱推导的系统发育结果主要分为三个簇。这些可以为其中一些论点以及新的结果提供证据。
