Abstract: In this paper, the RLCcircuit model for transmission and transpiration of plant moisture is established. No difference can be found between the results of direct determination and model analysis on thresholds of initation, continuation and attenuation of stomatal oscillations of Glycyrrhiza inflata. The stomatal oscillation is initiated and its amplitude is being enhanced when the transpirational pulling force (F) is larger than the resistance(R). The amplitude and frequency of stomatal oscillation are not changed when F=R. The oscillation begins to be weakened when0<(R-F)<2√L/C, and doesn't appear when(R-F)>2√L/C. Under this experimental condition, the Rof G. inflata is 3.1×109MPa·m-3·s and the 2√L/C is 3.11-3.64×105MPa·m-3·s.
