Results of investigations are reported on the role of acid-soluble phosphorus compounds in the process of winter wheat vernalization. Fractionation of germ extracts by the precipitation method revealed the dynamics of phosphorylated glycolysis metabolites during germination. The variability curves for spring wheat germinated at 1.5° and 22° and for winter wheat at 1.5° had a similar course, only that for winter wheat germinated at 22° showed differences. It is concluded that glycolysis is essential in the process of vernalization
