Abstract
The influence of the "residual solution" by wheat vernalization upon the earing of wheat was examined. 1. Some substances are supposed to diffuse into the surrounding medium (water) from the seeds during the course of vernalization, and this diffution seems to compose one of the causes of vernalization. 2. The diffusing substances are considered not to be characterized as a hormones. No positive effects of hastening the earing of the plants can be recognized.
