    The goal of the study was the assessment of the elongation growth of the naked oat var. 'Akt' to the contents of the toxic dosage of cadmium. Cadmium in toxically doses 20 and 100 mg per 1 kg of the soil and the control variant (0 mg Cd per 1 kg of the soil) were used in the pot experiment. The kinetics of plant elongation growth was analysed by means of a logistic function. The coefficients of logistic model have been estimated numerically by means of the Levenberg-Marquardt method. The applied dose of cadmium 20 mg · kg–1 of the soil did not significantly limited the elongation growth of the oak plants. The cadmium dose of 100 mg · kg–1 in the soil had an adverse influence on the growth as a result the stage of the maximum growth speed was about 10 days delayed in comparison to the control variant and the final height of plants was significantly limited.
