IAA, kinetin and ABA in a concentration of 10-7M did not cause major changes in the activity of ribonuclease in both cultivars. IAA and kinetin in a concentration of 10-5M lowered the activity of the tested enzyme, more in the 'Union' than in the 'Lubuski' cultivar. ABA in a concentration of 10-5M did not change the activity of ribonuclease in both cultivars. It caused, however, the appearance of an extra band with ribonuclease activity on the polyacrylamide gel in both cultivars
