Research of the plant’s functionality state during pulsed light stimulation

Effective and controlled plants development in artificial conditions today represents an urgent problem. Registration of bioelectrical potentials of the plants is still the best way of evaluation and diagnostics of the physiological functionality state of the biosystem. Very important role is played...
