Abstract: In this paper the results of the influence of various metabolic inhibitors on different periods of the vernalization process in winter wheat are provided. It was found that the initial period of vernalization is very sensitive to respiratory inhibitors such as azide and 2, 4-nitrophenol. In the middle period, the inhibitor of nueleoacid metabolism such as 2-thiouracil significantly prolongated the process of vernalization. At the third period the protein metabolic inhibitor such as chloromycetin strongly inhibited the vernalization process. Our experiments demonstrated that a remarkable replacement of metabolic patterns is existed in the course of vernalization of winter wheat. The relative metabolic processes during the time of vernalization not only carried on different in rate and in action model of inhibitors but also alternatively. Therefore, we assumed that vernalization process of winter wheat may be divided into several periods (sub-processes) with different metabolic patterns. On the basis of our results, we tentatively concluded that there are at least three sub-processes during the vernalization: the first sub-process is mainly determinated by carbonhydrate oxidation and phosphorylation processes; the second sub-process is mainly determinated by nucleic acid metabolism and the third sub-process is mainly determinated by the protein metabolism.
