Objective: To Study the photo-electric behavior of Spinacea pleracea by using the T.E-model of chlorophyll pigment. Methods/Statistical Analysis: The technic and method employed consisted on modeling the chlorophyll as an electrical circuit, to make a statistical analysis of electric conductance process of S. pleracea in light and in darkness by evaluating, the statistical average and statistical autocorrelation function, and make a temporal analysis by evaluating, the temporal average and temporal autocorrelation function. Finding: The electric conductance of Spinacea pleracea leaf plant increases when one passes from darkness to light; the spectral density of power (DSP) of the electric conductance process G(ω,t) under darkness is up to the DSP of the signal when S. pleracea is under light for the whole value of the reduced normalized frequency; the process is non-statistics in the broad sense (SSL) and non ergotic. The resemblance of the flow charge evaluated by autocorrelation functions for different values of the shift parameter is higher in light than in darkness. Application/Improvements: This study provided an additional tool to have an idea about the state of reactional center of photosystem II, knowing that the fluorescence emission testifies the loss of energy during the transfer of excitation to the reactional centers. In the same way, the electric conductance testifies the transfer of electrons released from the special chlorophyll ‘a’ of the reactional center to the photosynthetic channel.
