Wolff, S; Luippold, H E

In Tradescantia microspores, postirradiation treatments can modify the numbers of chromosome exchanges induced by x rays. The postirradiation inibition of respiration by anoxia or carbon monoxide in the xam dark prevents the rejoining of breaks and consequently allows breaks to remain open and capable of forming exchanges with breaks induced later. The results with Tradescantia are qualitatively similar to the results ob tained with Vicia in that irradiation in the presence of oxygen produces inore breaks than does anoxic irradiation and that for rejoining cellular respiration (the production of ATP) is required.
