The material basis of varietal differences in flowering habit was investigated from the standpoint that flowering is determined by the balance in amounts of flowering promotor and inhibitor. The grafting method was used throughout the experiments. Late variety of Glycine max L. seems to produce flowering inhibitor (or inhibitors) under the conditions under which midseason variety produces flower. Early variety seems to produce flowering hormone which overcomes the flower-inhibiting action in the late variety. The amount of flowering hormone produced under short day condition by midseason and late varieties were compared. The results show that, under the short day condition, the midseason variety produces equal or smaller amounts of flowering hormone as compared with the late variety. On the basis of these results, the mechanism by which the flowering habits are determined in various varieties of soybean plants was discussed.
