Description
Summary:Deformation curves in uniaxial compression of raw potato tuber were analyzed at Nicola and Saturna varieties. In the first part of deformation (time 1 min), some part of specimens were loaded by electric field simulating simultaneous measurement of the specimen alternating-current conductivity (three levels of voltage 1, 5, and 10 V and three frequencies 1, 10, and 100 kHz). The obtained curves were analyzed by six parameters. In five of them no differences were approved statistically (α = 0.05). Only in the case of modulus of elasticity some differences were observed; however, the differences cannot be simply explained by the influence of the electric field.
