The effect of germanium on physiological characteristics of rice plant in seedling stage and other developing stage was studied.The law of translocation and accumulation of germanium in rice plant and soil was explored.The results of experiments showed that low concentration of germanium increased the growth and development of rice,while high concentration of germanium inhabited the growth and development of rice plant or caused poison effect.The effects of germanium on physiological characteristics of rice plant were different with types of seedlings.
