This experiment was carried out in 1957 to clear the mechanism of submerging injury to naked barley on heading stage. The variety used was Akashinriki, and four plots were designed basing on the submerging duration under clear water, i.e., 0 (control), 8, 16 and 24 hours plots. The results of the experiment were summarized as follows : The relative yields of grain per plant in submerged plots were 52.7, 19.8 and 23.4%, respectively, to control. The lowering of products above-mentioned was due to both of occurrence of sterile spikelet and decrease in number of heads per plant. The former was caused by the failures of anther dehiscence and pollination, sterilizing of pollen and non-functioning of female organ. The latter was caused by the decaying of head after the interruption of internode elongation in parent stalk and early appeared tillerings.
