According to literature, electrostimulation of plants can induce plant movement, activation of ion channels, ion transport, gene expression, enzymatic system activation, electrical signaling, plant-cell damage, enhanced wound healing, and can also influence plant growth. Many plants can communicate above ground and underground between adjacent plants. Electrostimulation by square pulses induces passive electrotonic potentials propagating within and between tomato plants. The amplitude and sign of electrotonic potentials, in both the electrostimulated and neighboring tomato plants depends on the amplitude, rise and fall of the applied voltage. Electrostimulation by the pulse train, sinusoidal and triangular saw-shape voltage profile shows the existence of electrical differentiators and refractory periods in cell-to-cell electrical coupling in tomato plants. Electrical networks within one tomato plant can communicate underground with electrical circuits in another tomato plant. Here, we present the mathematical model of electrotonic potentials transmission between tomato plants which is supported by the experimental data. The information gained from this mathematical model and analytical study can be used not only to elucidate the effects of electrostimulation on higher plants, but also to observe and predict the intercellular and intracellular communication in the form of electrical signals within the electrical networks within and between tomato plants.

番茄植株内部和植株之间的电信号传播

根据文献,植物的电刺激可以诱导植物运动,离子通道激活,离子迁移,基因表达,酶系统激活,电信号传导,植物细胞损伤,增强的伤口愈合,并且还可以影响植物生长。许多植物可以在相邻植物之间进行地面和地下通信。方脉冲的电刺激引起在番茄植株内部和植株之间传播的被动电渗势。在电刺激的和邻近的番茄植株中,电动势的幅度和符号取决于施加电压的幅度,上升和下降。通过脉冲序列进行电刺激,正弦和三角形锯齿形的电压曲线显示了番茄植物细胞间电耦合中存在电微分器和不应期。一个番茄植物中的电网可以与另一番茄植物中的电路进行地下通信。在这里,我们提出了番茄植物之间的电渗势传递的数学模型,该模型得到了实验数据的支持。从该数学模型和分析研究中获得的信息不仅可以用于阐明电刺激对高等植物的影响,还可以观察和预测番茄内部和之间的电气网络中的电信号形式的细胞间和细胞内通讯。植物。一个番茄植物中的电网可以与另一番茄植物中的电路进行地下通信。在这里,我们提出了番茄植物之间的电渗势传递的数学模型,该模型得到了实验数据的支持。从该数学模型和分析研究中获得的信息不仅可以用于阐明电刺激对高等植物的影响,还可以观察和预测番茄内部和之间的电气网络中的电信号形式的细胞间和细胞内通讯。植物。一个番茄植物中的电网可以与另一番茄植物中的电路进行地下通信。在这里,我们提出了番茄植物之间的电渗势传递的数学模型,该模型得到了实验数据的支持。从该数学模型和分析研究中获得的信息不仅可以用于阐明电刺激对高等植物的影响,还可以观察和预测番茄内部和之间的电气网络中的电信号形式的细胞间和细胞内通讯。植物。
