Abstract
The composition of nucleic acid preparations isolated from seedlings and leaves of plants grown from vernalized and nonvernalized winter wheat grain was chromatographically investigated on a methylated albumin kieselguhr column (MAK column). The intensity of synthesis of the particular nucleic acid fractions was compared by the 32P-incorporation technique and the nucleotide composition of the newly synthesized nucleic acid fractions was determined. It was observed that the rate of 32P incorporation into the sRNA, rRNA+mRNA and TB-RNA fractions of the leaves of vernalized plants was about two times higher as compared with that in the nonvernalized control.
