 note = {1. The potassium contained in turnip and radish seeds was investigated by the flame spectrophotometric method. 2. The average K_2O content contained in turnip seeds of middle size was 1.73%, and that in radish ones, 2.79%. 3. A remarkable change of K_2O content was found in the germinating seeds in the case of the turnip as well as of the radish. The first peak of K_2O content in the cotyledon was found immediately before the formation of root, and the second peak was followed by the development of the first leaf. (Fig. 2, Fig. 3) This tendency did not seem to vary by the addition of nitrogen and phosphoric acid. 4. The potassium in seed coats decreased gradually in proportion to the days elapsed after germination. 5. From the results above mentioned, the cotyledon seemed to be the depot for potassium during the first stage of growth of the turnip and the radish., Article, 信州大学農学部学術報告 5: 1-6(1956)},
