[In vivo impedance of the aerial organs of some mono- and dicotyledonous plants].

In vivo impedance of the aerial organs of some mono- and dicotyledonous plants. We measure in this paper the electrical capacitance and resistance of aerial organs of some plants, grown in the laboratory (sunflower, pumpkin, and maize, of different ages) or bought at the market (sorrel), in a range of 34 frequencies, from 40 Hz to 100 kHz. The electrospectrometric curves of the leaves aged 14 days of the dicotyledoneous studied are close to each other.
