Abstract

The characteristics and intensity of rRNA synthesis occurring at temperatures around freezing point were examined in connection with frost hardiness in wheat cultivars. The intensity of rRNA synthesis taking place near freezing point showed a close positive correlation with the critical temperature (LT50) characteristic of the frost resistance of the varieties. The quantity of high MW precursors to rRNA appears to be heterogeneous in hardy and non hardy varieties at low temperatures and point primarily to an inhibition in the maturation processes of ribosomes in the final nuclease processing step in non-frosthardy varieties.
