Studies on the development of peanut seeds, : I Formation of oil and protein related to seed development.

[摘要] This study is preceded by making clear of the formation-process of fat and protein involved in the seed which is an object for tne production, to establish firmly the theory of peanut-cultivation. The results of experiments summarized are as follows: 1. The size of the pod on the 35th day after flowering, and the sizs of the seed on the 42nd after are to be almost at their max. 2. The raw-weight of the pod is to become its max. on the 35th day after flowering and is afterwards likely to decrease, but the raw and dry-weight of the seed keep to increase up to the 84th day gradually. The dry-weight of the pod is to continue to increase up to about 70th day gradually and is afterwards to decrease a bit. 3. Fat involved in the seed is to become its max. nearly on the 77th day after and the Iodine value is to show its greatest on the same day after. 4. Protein is te be its max. on the 77th day after flowering and afterwards decreases a bit. 5. Ashes are abundant in the pod during the beginning of growth, ashes in the pod is afterwards to keep to decrease and become constant on the 77th day after. Ashes in the seed are tobecome nearly constant on the 70th day after.
