Abstract

Seeds with varying moisture content (3-14 per cent) were X-irradiated with doses of 0, 10, 12·5 and 15 kR. Radiation-induced changes in the length of root and shoot, and their fresh and dry weights indicate that the seeds show maximum radioresistance at intermediate moisture levels and that the shoot is more sensitive to X-rays than the root. There was no significant modification of DNA, RNA and acid soluble (AS) content while protein content was adversely affected by radiation irrespective of seed moisture. However, no change in total macromolecular content could be detected in the plant as a whole.
