A testimony of inter-plant communication through electrophysiological signal analysis

Abstract

Plant responses to changes in environment are allied with electrical excitability, signaling and are observed by their electrophysiological signals. Similarly communication in between various plants is noticed by continuous monitoring of their electrophysiological signals at same instant comparatively. Signal acquisition is done with help of BIOPAC ® MP36 set up. Two plants of different species connected to two different channels at a time clearly visualized the amplitudes and frequencies with which plants pulsated during their sensory perception, communication and adaptation to eventual stimuli. The variation in signal potentials of plants depend upon intensity of stimulus perceived either from environment or neighboring plant. They communicate with each other through electrical signals using air as a medium; they are conscious enough to aware neighborhood about hazards and threats. This paper presents in detail the potential and frequency variations that plants illustrate during Inter-plant communication. Highlighted Conclusion The meticulous sensory perception of plants when they endure mechanical, heat and chemical stimuli clearly revealed that plants are highly sensitive to environmental changes. The communication in plants is not only intra-specific but from experimental results it is concluded that plants are good enough in stress/danger perception and self-defense clearly inter-plant communication exists. Many scientists belonging to different times and cultures (e.g., Burdon-Sanderson 1873, Darwin 1875, Bose 1926, etc.) have clinched a belief that plants have much more intricated abilities than they are commonly perceptible. Instigated by a consistence with Grover Cleve Backster's theory of 'Primary perception' that plants have ability to sense and respond to environmental stimulus, the signal transmission in plants is not only intra-specific but their inter-specific communication escorts to a term Plant Intelligence. Plants do not have a brain or neuronal network, but reactions within signaling pathways may provide a biochemical basis for learning and memory in addition to computation and problem solving. Plants have ability to distinguish between light and dark. They communicate using air, roots as the transmission media, they are conscious enough to aware neighborhood about hazards and threats. Conscious energy exists in everything; it depends on the matter that utilizes it. Merely matter is all energy pulsating with different frequencies and amplitudes. The frequencies and amplitudes with which plants pulsate can be characterized by monitoring the (Electrophysiology) electrical signals of plants. It is evident that electrical signals play a major role in many plant processes like photosynthesis (Koziolek et al. 2004), water intake (Davies et al. 1991), communication (Muller et al. 2006), detailed sensory perception (Roblin 1985, Mancuso 1999, Rhodes et al. 1996), respiration (Dziubinska et al. 1989), learning and memorizing the eventual stimuli etc. Electrocardiogram and Electroencephalogram (ECG & EEG) are also categorized as Electrophysiological recordings of human beings. Action Potential (AP) and Variation Potential (VP) are two different electrical signals observed in plants. The electrical pulse propagating rapidly with a constant velocity by maintaining constant amplitude is Action Potential (Fromm 2006). Variation Potential (slow wave) shows variation in the electrical pulse either to a long range or a short range depending upon the intensity of the stimulus provided (Stahlberg et al. 2006). Its velocity
