Resistance and reactance of wheat leaves at 42 frequencies were determined

which were attributed to five varieties such as dryland

irrigated area and dry-fertilizer.The wheat grown in pots experienced three water conditions: optimization moisture

moderate drought and severe drought.Electrical impedance spectroscopy of wheat leaves were acquired in three moisture states.The results showed that electrical impedance spectroscopy of wheat leave was a single arc

with a depressed center.Amplitude and characteristic frequency of the spectroscopy showed obvious regularity in different moisture state.With drought degree enhanced

characteristic frequency of spectroscopy mostly increased.Amplitude of the spectroscopy didn’t behave the same trend among diverse drought resisting model.Amplitude of dryland variety has a sustainable growth in drought stress.Amplitude of dry-fertilizer reduced a little at moderate drought and then increased at severe drought.Amplitude of irrigated enhanced at moderate drought and then decreased at severe drought.The rules would have reference value to the research of drought resisting of wheat.
