摘要

Recent studies show low-amplitude and complex-shaped electrical signals in plants. These signals are important for plant life as they are induced by weak, natural stimuli and can trigger substantial physiological responses, but their manual analysis via traditional metrics is challenging. A novel integrated approach, electrome analysis, offers an alternative solution; however, its efficiency under varying conditions requires further investigations. This study aimed to compare the plant electrome parameters under osmotic stress (mannitol) in both natural and laboratory conditions. Using macroelectrodes, we measured the electrical activity of wheat plants and analyzed standard deviation, approximate entropy, and exponent β of power spectral density of surface potential. It was shown that plants in natural conditions had lower initial synchronization in the electrical activity and lower electrical responses than ones in laboratory-grown plants. The desynchronization is likely due to the low sensitivity to osmotic stressor of plants under environmental conditions. It shows that laboratory models may not fully represent the complex electrical signaling occurring in nature.
