  • This study was examined for the effect of tuber size, bud and tuber removal, and tuber cutting on growth of Eleockaris kuroguwai Ohwi. Elongation of plumule and radicle, and the weights of tuber, rhizome and shoot were increased as tuber size is large. The weights of shoot and tuber reduced by bud planting without tuber at 15 days after budding, however number of tubers were increased compared with normal tuber. When cross-cutting tubers were seeded, the weights of shoot, rhizome and tuber were produced as 84%, 85%, 71%, respectively compared with normal tuber, and the number of tubers was not influenced. The weights of tuber, rhizome and shoot were lowed as the bud removal, and there were a great number of tubers at bud removal of 15 days after budding. Tuber of E. k, contained as nonfibrous 78.9gr, phosphorous 77mg, iron 16.8mg, niacin 1.3mg per 100gr edble portion. The positive correlations were observed between shoot weight and tuber weight, and number of tubers.
