The growth characteristics and Germanium (Ge) absorption of rice plant (Hopyung) were investigated under different soil texture such as silt loam, clay loam, loam and sandy loam in pot (1/5,000a) in order to produce a functional rice with germanium (Ge) in
. The soil was treated with 8 mg/kg Ge. The growth status of rice plant was almost similar in all soil texture, and rice yield was higher in the order of silt loam > clay loam > loam > sandy loam. In rice gran, the Ge content in silt loam, clay loam, loam and sandy loam were 980, 868, 754 and 803 ug/pot, respectively. The Ge content of brown rice and polish rice were greater in the order of silt loam > sandy loam > clay loam > loam. In silt loam, the Ge absorption rate in leaf, stem, root, rice grain and brown rice were 19.7, 2.3, 0.03, 3.1 and 0.44%, respectively. Therefore, the optimum soil texture for production of functional rice with Ge is a silt loam.
