Abstract : An attempt was made to determine radiation effects on enzyme systems in living tissues by the use of tetrazolium salts. Plant seeds irradiated with x-rays and then treated with tetrazolium salts show that the irradiation effect can be detected by changes in the reducing power of the enzyme systems and can be measured by the amount of colored formazan formed. The relation between dose and radiation effect on the reducing systems can be written in exponential functions with a constant characteristic for the proper enzyme systems. The environment is of great importance. The radiation effect is altered when seeds are irradiated in the wet or dry states, different pH values, pre-or post-treatment with various chemicals, etc.
