Abstract :
Dielectric properties of fresh leaves samples from different plant species were studied over the frequency range 10-3 to 104 Hz. The dynamic behaviour of the conductance and capacitance in leaf samples has been observed to follow fractional power law. The observed power-law dispersions have been modelled using frequency dependent resistive and capacitive elements of a conventional equivalent circuit
