Study on Plant Electric Potential Variation in Cucumber Growing under Water Stress

摘要：

Action potentials (AP) and variation potentials (VP) were measured in four-week old cucumber under different watering disposals. External stimuli (e.g. changing temperature, wounding or chemical compounds, and the density of light) cause an action potential to be generated and change the variation potential from the original steady state level. The paper discussed that the effect of water stress on plant physiological signals (AP and VP) which were induced by environmental factors such as heat wounding, light and electrical stimulation. Under environmental stimulations, the effect of water stress on variations of plant potentials mainly focus on APs, water stress enlarged the amplitude of APs which reached 50-60my and speed up the propagation speed of APs, which increased from 0.2m/s to 0.5mm/s.
