Plants have sensory, short-term and long-term memory. Possible candidates for memory in plants are memristors; resistors with memory. Memristors have been found in seeds, plants, flowers and fruits. The electrostimulation of plants by bipolar periodic waves can induce electrical responses with fingerprints of volatile or non-volatile memristors. Here, we show that the electrostimulation of the Venus flytrap (Dionaea muscipula Ellis) by unipolar sinusoidal or triangular periodic electrical trains induces electrical responses in plants with fingerprints of volatile memristors. The discovery of volatile generic memristors in plants opens new directions in the modelling and understanding of electrical phenomena in the plant kingdom.
植物具有感官、短期和长期记忆。植物中的记忆候选物可能是忆阻器;具有记忆功能的电阻器。忆阻器已在种子、植物、花朵和果实中被发现。通过双极周期性波对植物进行电刺激可以诱导出具有挥发性或非挥发性忆阻器特征指纹的电响应。在这里,我们表明,通过单极正弦或三角周期性电脉冲对捕蝇草(Dionaea muscipula Ellis)进行电刺激会在植物中引起具有挥发性忆阻器特征指纹的电响应。在植物中发现挥发性通用忆阻器开辟了在植物王国中对电现象进行建模和理解的新方向。
