Abstract

The correlation of the cold-induction of rRNA synthesis in winter and spring wheat varieties with the rRNA-DNA hybridisation of these varieties and the increase in the intensity of cold-induced rRNA synthesis was examined. The results indicate that the cold-induced increase in the intensity of rRNA synthesis at low temperatures in frost resistant wheat varieties is primarily due to the higher rRNA cistron number in winter varieties. A close correlation can be observed between the percentage of rRNA-DNA hybridisation and the increase in cold-induced rRNA synthesis, which indicates that the activity of rRNA cistrons varies as a function of temperature.
