Abstract
Using the same samples as in the first report, analyses were made for determination of organic constituents, which are crude-protein, crude-cellulose, lignin and carbohydrate in the leaf-and-stem and the ear. The following results were obtained : 1) At the early stage of growth, protein is formed actively. After the ear-forming stage, much cellulose and lignin are formed and after the flowering stage, carbohydrate is formed in comparatively large amount. 2) Most part of the carbohydrate which is accumulated in the ear is a product of assimilation after the flowering stage. 3) Most part of the protein which is accumlated in the ear is what was reserved in the leaf-and-stem befor the flowering stage. 4) Cellulose and lignin seem to be only the frame-work of the field where the physiological phenomena are taking place.
