The modification of radiosensitivity of barley seeds with 11.1% water content by caffeine and cysteine applied during post-irradiation oxygenated and oxygen-free hydration was studied. No post-irradiation oxygen-dependent damage developed in these seeds. While cysteine had no influence at all, caffeine effectively potentiated the level of the gamma-induced oxygen-independent (Class I) component of damage. The possible reactivity of caffeine towards the precursors of the oxygen-dependent and -independent components of damage in determining the mode and magnitude of modification is briefly discussed.
