In order to detect fractures in the plant tissue resulting from deformations, the method of acoustic emission has been applied. Simultaneous measurements of the mechanical parameters and the acoustic emission signal show that the destruction of the cell structure begins at the lower deformation values than the ones at which there is a decrease in the stress level. The results obtained show that the method of measuring the acoustic emission signal allows for an early detection of plant tissue defects arising from the activity of external forces.
