The authors performed this experiment for the purpose of knowing the difference between the transplanted plant and the not-transplanted one of upland rice. The results are briefly summarized as follows. 1. The forms of the root systems of the transplanted plants are cylindrical in the early stage and in the later stage, are geoidal. On the contrary, that of the not-transplanted ones are oval inversely. 2. The roots of the transplanted plants recover their losses during 3〜4 weeks after transplanting. And after then the number of roots and weight of their dry matters increase rapidly as compared with the not-transplanted plants. 3. The 100 grains weight, hull weight, length, lateral diameter and dorsoventral diameter of the grains of the transplanted plants are superior to those of the not -transplanted ones. Especially, these superiority are more markedly in the weak grains. 4. But the yield of transplanted plants are inferior to the not-transplanted ones.
