| Abstrakt: | Abstract: The paper contains short description of a special device developed for study of electrical after-effect in vegetable cellular tissues after short electric pulses applied to the tissue. The device contains generator of the pulses and the microprocessor controlling circuits for time arrangement of the pulse amplification and collection of data for further evaluation. The pulses are based on AC signal with freguency 10-100 kHz with the amplified voltage up to ±240V and duration 1-10 ms. After finishing the individual pulse, the AC source signal continues, but amplitude on the tissue is 21. 5times lower. The data about AC voltage and current intensity are continuously collected with frequency 800 kHz and the fed to PC USB input that was used to calculate time chart of electric properties of the tissue, its complex permittivity and specific complex conductivity. An example of the obtained results on potato tissue is given. |
