[Radiobiological characteristics of chilled seedlings as an object for inflight experiments].

It is recommended to use for experimentation cooled plant seedlings in the stage of delayed growth. Cooled seedlings have a high sensitivity to the environmental effects and can be used in long-term (up to 1-2 months) experiments. The influence of suboptimal temperatures on the radiosensitivity of seedlings, the development of radiation injury and maintenance of the radiobiological effect is described.
