Abstract
IT has been found that the frequencies of X-ray induced chromosomal aberrations in the root-tips of Vicia faba at low oxygen tensions is much higher in the presence than in the absence of respiratory inhibitors1,2. The inhibitors were effective only in the presence of oxygen, and their effect appeared to consist essentially of causing the oxygen effect3 to appear at much lower oxygen concentrations than it does in untreated roots. It was suggested that the chemicals in question enhance the X-ray sensitivity by eliminating an oxygen gradient, which is thought to exist in the roots at low oxygen tensions2.
