Abstract

Important as it is, the iodine content of sea-weeds has not drawn much attention as to its seasonal variations. The material, on which our study is based, was obtained from the coast of the Ibaraki Prefecture, comprising two species, viz., Turbinaria fusiformis YENDO and Ecklonia bicyclis. In the accompanying figures the iodine content of the sea-weeds is plotted against months, that for the months of 1935 being each represented by a cross and that for those of 1936 by a circle. Fig. 1 shows that the iodine content of Turbinaria fusiformis reaches its maximum in February to March when the reproductive organ of this sea-weed ripens. As shown in Fig. 2 the maximum of iodine content of Ecklonia bicyclis is not well defined but lies around December and January when the reproductive organ of this sea-weed is very likely to ripen in the district in question.
