Since a particular fraction of rye diffusate obtained by mean of continuous paper electrophoresis strikingly promoted the flowering of winter wheat, uridylic acid, which was supposed to be the main active substance in the effective fraction of rye diffusate, and its analogues were applied to the plants of winter wheat (Norin No. 58) in juvenile stage. The application of uridylic acid (200 ppm) to the 3rd and 4th leaves of the wheat was most effective in promoting flowering and decreasing the number of leaf on main stem. Effects of chilling and chemical treatment on flower-promotion were examined in winter wheat, and a vernalization-like phenomenon caused by chemical treatment was clearly recognized. The experimental results reported in this paper may predict the possibility of the fact in which vernalization is induced by vernaline, although the complete nature of vernaline is not yet known.
