1) Comparative study between diploid and tetraploid buckwheats, Fhagopyrum esculepttuam, have been made concerning the contents of water and total nittogen in several organs at different stages of growth. 2) On the whole no significant difference was :noted between the diploids and the tetraploids in the relat.ive, total amount of water and of total nitrogen during their whole growth period. It was, however, noticed that the mode of change in the contents of these substances was remarkably different between the two in some organs as well as at some stages of growth. 3) Significant difference in- water content was displayed in the stem at two stages, vis., the beginning flowering and the early fruit develop ment, giving higher content in the diploids than in the tetraploids. Although not significant, the leaves of the tetraploids were observed always to shotv the tendency of having higher water content than those of the diploids throughput the period from germination to early fruit development. At the stage of maturity, however, the situation was quite reversed, the latter being predominant in the content than the former.
