Rape and sesame plants were cultivated with P^<32> containing culture solution and the distribution of P^<32> in the various parts of plants were investigated at each stage of the plant growth. In the rape experiments, the radioactive solution was supplied to the crops during the period from Jan. 1 (112th day after sowing) to Jan. 7. After the treatment, the crops were cultivated by the standard culture solution containing nonradioactive phosphorus. On each of the following days, 8/Jan., 5/Feb., 4/Mar., 1/Apr., 22/Apr., the plants were sampled and estimated their total phosphorus and the radioactivity. In the sesame experiments, the radioactive solution was supplied to the crops during the period from July 30 (40th day after sowing) to Aug. 5. After the treatment, crops were sampled every week and estimation were performed. The results are shown in the Tables 1,2 and Figs. 1-4.
