SATOO, Taisitiroo (Dept. For., Fac. Agr., Univ. Tokyo). 1979. Production of reproductive organs in plantations of Chamaecyparis obtusa near an electric power plant in Owase, Mie. Jap. J. Ecol. 29 : 315-321. The production of cones, seeds, and male-flowers was estimated on three sample plots described in the previous paper. Production of cone and seed was much smaller in plots located within the same basin as the power plant than a plot located outside of it. Seed-fall was very slight before December when the greater portion of the seed fell, and it continued to decrease gradually until April. Any specific trend was not recognized in the seasonal pattern of cone-fall. Except for the largest trees, among the trees of the same diameter at breast height, production of cones and seeds was larger in the plot located outside the basin than those within it. Shedding of male flower occurred in April and May. Production of reproductive organs in the sample plots within the same basin as the power plant was much smaller than those in the plot which is separated from the plant by a mountain range.
