The Venus flytrap captures insects with one of the most rapid movements in the plant kingdom. There is a significant difference between properties of electrical signals generated in the Venus flytrap described in literature. Amplitudes of action potentials vary from 14 mV to 200 mV with duration of signals from 2 ms to 10 s. Here we present experimental study of potential differences between Ag/AgCl electrodes inserted to the trap, petiole, and into soil or external ECG electrodes attached to surfaces of the Venus flytrap. Diverse types of electrodes with various positions in a plant tissue or in soil show different amplitude and duration of electrical signals because potentials are measured in different electrochemical circuits. Electrical signals in the Venus flytrap were induced by mechanical stimulation of the trigger hairs or by chemical stimulation of a midrib using small drops of H₂O₂ or HNO₃. Here we found that action potentials can propagate with speed up to 10 m/s in the trap of D. muscipula. Results are compared with equivalent electrical circuits.

金星捕蝇器以植物界中动作最迅速的动作之一捕获昆虫。在文献中描述的金星捕蝇器中产生的电信号的特性之间存在显着差异。动作电位的幅度从14 mV到200 mV不等，信号持续时间从2 ms到10 s。在这里，我们介绍了插入诱捕器，叶柄，土壤或附着在维纳斯捕蝇器表面的外部ECG电极之间的Ag / AgCl电极之间电势差的实验研究。在植物组织或土壤中具有不同位置的各种类型的电极显示出不同的电信号幅度和持续时间，因为电势是在不同的电化学电路中测量的。₂ O ₂或HNO ₃。在这里，我们发现动作电位可以在D. muscipula的陷阱中以最快10 m / s的速度传播。将结果与等效电路进行比较。
