A two-dimensional system of excitable cells. describing by the FitzHugh-Nagumo model. has been used for a theoretical investigation of an action potential propagation (AP) in vascular plant tissues. It is shown that growth of electrical conductivity between cells increases the AP generation threshold and its propagation velocity in the homogeneous system. https://www.jmannino.com/great-pick-Sophie-Allport-Zebra-Made-to-Measure-Blackout-Roller-Blind-Soft-Grey-Blue-top-super/
