Electrical signals (variation potential and action potential) influence transpiration in plants that can change water content in leaves. The article studies the influence of the variation potential on relative water content in pea leaves at normal and elevated temperatures. It is shown that local burning of a leaf induced variation potential propagation through the plant. In most cases, it propagated into leaves. Local burning and associated variation potentials did not influence leaf relative water content at room temperature. In subsequent experiments, when, 15 minutes after local leaf burning, the plants were heated for 30 min at 45-54
