This report is described on the consumption process of the reserve foods in endosperms of the rice seeds during germination in relation to the growth of rice. (1) The curve of consumption of reserve foods in seeds and the growth curve were represented with S type curve. The development of plants in the foods-exhausted period was "the fourth foliage leaf and 5〜7 crown roots" stage. (2) On the comparison of the manured plots with the non-manured plots. a) The growth of the tops and the total dry matter of plants were superior in manured plots, while the growth of roots was rather inferior. b) The reserve foods in seeds were exhausted more rapidly in manured plots. c) The growth in the foods-exhausted period slowed considerably in the no-manured plots, while in manured plots the growth curve in the same period may by changed smoothly into the following independent period. (3) When the reserve foods in endosperms of seeds were removed before those foods will be exhausted, the growth on the following day was sluggish, but the growth was recovered gradually. (4) The reserve foods in seeds were exhausted more rapidly under the higher temperature of soil than under the lower temperature.
