Studies on the Kuzu (Pueraria sp). : 1. On the seeds of wild Kuzu,

[摘要] 1. For the study on the cultivation of Kuzu, especially the fundamental study of its increase, form and power of wild seeds were investigated first. 2. Between the legume length and seeds which were embraced in one legume, the correlation ratio was found 0.881±0.005, but its good seeds were very few, (24.3%), even the legume which was grown completely. For instance, the means of flat legume were 55.12±0.406 mm in length, 7.80±0.021 mm in width. 3. The seed was reniform, navel was round and white, and navel seam was clearness, but the location of micropyle and radicle was indistinct from outside. It had water as the ratio 13.39%, weight of a thousand seeds was 12.441 g and its specific gravity was 1.106. 4. As the result of germinating examination, the ratio of energy and hard seeds was each 10% and 50∼60%. It will be the most effective method for that the hard seed is removed, to hurt the seed coat. If the hard seed is removed perfectly, its germinating energy will rise about 90%. On the method that the hard seed is soakd in sulphuric acid, its germinating power rises, but when its soaked short time, this method shows scanty effect for that the hard seed is removed.
