Abstract
The effect of gamma radiation on dormant seeds of Avena fatua L. (wild oats) has been investigated. A. fatua seeds require a long after-ripening period for germination. Gibberellic acid and cold treatments are known to break seed dormancy. 10 kR of gamma radiation also produced an effect similar to these treatments. Shoot length and dry matter content of seedlings raised from 10 kR gamma-irradiated seeds were similar to those raised from control seeds. Higher radiation doses promoted seed germination but they also caused a reduction of seedling growth. Probable mechanisms by which gamma radiation may bring about these effects have been discussed.
