Abstract

The intensity of rRNA synthesis taking place in wheat seedlings at low temperatures and its quantitative variation during the hardening process were examined. Chilling approximately doubles the intensity of rRNA synthesis in winter wheat at low temperatures, while it has no effect on non frost-resistant spring wheat. No significant change, characteristic of the hardening period, can be observed in the percentage of DNA hybridized to rRNA due to the effect of the chilling. These results indicate that the cold-induced increase in the rRNA synthesis during the hardening period is not associated with a gross amplification of the rRNA genes.
