Alterations in Growth Due to X-Rays; MODIFICATIONS DE CROISSANCE DUES AUX RAYONS X

Technical Report ·
OSTI ID:4273062
If dry barley grains are subjected to x radiation, the length of the coleoptiles is affected. All mitoses are inhibited by 200 kr. A study was made of the effect of various factors on this elongation. It is increased by prior hydration of the grain and by low and high temperature treatment. Long latency periods between irradiation and germination will suppress the phenomenon. Latency times of over 20 days accentuate mitotic inhibition and reduce coleoptile elongation. Reduced glutathione and cystamine have an effect comparable to a latency time of 20 days. In the case of cryptogamous plants, the increase in elongation could be attributed to the induction of adaptative enzymes in response to the action of the radiation. (J.S.R.)
