Both action potentials and mechanosensitive signalling are an important communication mechanisms in plants. Considering an information-theoretic framework, this paper explores the effective range of multiple action potentials for a long chain of cells (i.e., up to 100) in different configurations, and introduces the study of multiple mechanosensitive activation signals (generated due to a mechanical stimulus) in plants. For both these signals, we find that the mutual information per cell and information propagation speed tends to increase up to a certain number of receiver cells. However, as the number of cells increase beyond 10 to 12, the mutual information per cell starts to decrease. To validate our model and results, we include an experimental verification of the theoretical model, using a PhytlSigns biosignal amplifier, allowing us to measure the magnitude of the voltage associated with the multiple AP's and mechanosensitive activation signals induced by different stimulus in plants. Experimental data is used to calculate the mutual information and information propagation speed, which is compared with corresponding numerical results. Since these signals are used for a variety of important tasks within the plant, understanding them may lead to new bioengineering methods for plants.

植物中的交流：多种动作电位和机械敏感信号与实验的比较。

动作电位和机械敏感信号传导都是植物中重要的通讯机制。考虑到信息理论框架，本文探讨了不同构型下长链细胞（最多100个）的多种动作电位的有效范围，并介绍了多种机械敏感激活信号（由于机械刺激而产生）的研究）在植物中。对于这两种信号，我们发现每个单元的互信息和信息传播速度趋于增加到一定数量的接收器单元。但是，随着单元的数量增加到超过10到12，每个单元的相互信息开始减少。为了验证我们的模型和结果，我们使用PhytlSigns生物信号放大器对理论模型进行了实验验证，使我们能够测量与植物中不同刺激引起的多个AP和机械敏感激活信号相关的电压大小。实验数据用于计算互信息和信息传播速度，并与相应的数值结果进行比较。由于这些信号用于植物中的各种重要任务，因此理解它们可能会为植物带来新的生物工程方法。
