The temperature dependence of sugar-beet parenchyma tissue dynamic shear modulus has been studied. The dynamic shear modulus investigation was performed employing low frequency reverse torsional pendulum at the temperature ranging from 200 to 280 K. Percolation transition ($T_0$ = 251 K), stipulated by the generation of ice in the sugar-beet tissue, is discovered. The quantity of ice in the sugar-beet at the temperatures lower than the percolation transition temperature was calculated on the dynamic shear modulus temperature dependence in terms of the percolation theory. It is concluded that this transition corresponds to the appearance of an infinite ice cluster. One can maintain that the sugar-beet survives above the percolation transition temperature.
