The increasing interest in plant electrophysiology stems from the need to understand the complex signaling mechanisms that enable plants to perceive and respond to their environment. The main hypothesis is that changes in soil humidity, light intensity, and temperature will significantly impact plant signaling, whereas exposure to music will have a minimal effect. To investigate this, geranium plants were subjected to controlled variations in environmental conditions, and their electrophysiological activity was measured using AgCl electrodes and an ECG Arduino kit. The results revealed that increased soil humidity triggered a rapid, short-term spike in electrical signals, indicating a swift response to water availability. Conversely, elevated light intensity resulted in a gradual, long-term increase in electrical activity, reflecting a sustained response to light changes. Additionally, higher temperatures caused a prolonged increase in electrophysiological responses, demonstrating the plants' ability to detect ambient temperature changes. Interestingly, exposure to music, specifically classical music at moderate frequencies, did not significantly alter the plants' electrical activity, suggesting it does not directly affect plant physiology. These findings contribute to our understanding of plant neurobiology and the complex mechanisms through which plants interact with environmental stimuli. The results could have practical applications in optimizing greenhouse conditions and pave the way for future research on how plants perceive and adapt to their environment.
