The paper presents the results of studies on the changes of tensions taking place in the process of humidification of soybean seeds, Poland cv. Before humidification, which was performed at different temperatures, the material was heated with infrared heating. It was stated on the basis of the studies that treating the seeds with infrared heating was the cause of considerable decrease of the values of recorded pressures. The pressures appearing in the course of humidification of the thermally treated seeds were approximately 10 times as low in comparison with the pressures recorded while humidifying the seeds that were not subjected to any treatment.
