Abstract

The nature of rRNA synthesis in the plumula in the course of vernalisation at low temperature (3°C) was examined in four winter wheat varieties with different cold requirements (Triticum aestivum L. var. Bezostaya 1, Rannyaya 12, Mironovskaya 808 and Bánkuti 1201) using the pulse-chase technique. The presence of an rRNA synthesised at low temperature but decomposing at high temperature (25°C) was detected through its decomposition products, which have molecular weights of 1.05 × 106 and 0.57 × 106. It was found that the synthesis of this rRNA was dependent on the degree of vernalisation. It appears likely that the rRNA detected takes part in the specific metabolism of vernalisation.
