Investigation into the effects of ionizing radiations on growth, development and productivity of alfalfa

The purpose of this study was to establish optimal doses of gamma radiation for the normal growth and development of alfalfa and for securing the highest possible yields of hay and seed. It is concluded that: presowing irradiation of alfalfa seeds from a Cs137 source has a beneficial effect on alfalfa growth and development and on the yields of alfalfa hay and seeds; the optimal radiation dose for seeds is 1300 rad; the irradiated seeds retain their germinating power.
