Abstract

It was established that the dehydrase activity of maize grains is reduced with an increase in the radiation dosage, With a dose of 2.5 Mr, the dehydrase activity in dry grain decreases by 25%; in moist grain, by 30%, The respiration intensity of maize grain falls with an increase in radiation dosage, With a radiation dose of 2.5 Mr, the respiration intensity of dry grain is lowered 2.9 times, and the moisture, 4 times, High doses of radiation (2.5 Mr) are not lethal for the embryo cells of the seed, but considerably depress its respiration. Thus, with a dose of 2.5 Mr, the respiration intensity of the embryo cells is decreased 15 to 18 times. During storage for a term of360 days, the respiration intensity and dehydrase activity of dry gramsubjected to gamma- ray radiation remain unaltered. In the course of storage for a term of 90 days, there is practically no change in the respiration intensity and dehydrase activity in moist seeds irradiated with a dose of 2.5 Mr, (auth)
