To investigate the effect of inorganic (GeO<sub>2</sub>) and organic (Ge<sub>-</sub>132) germanium treatment on Brasica juncea C. plant, growth characteristics and Ge contents were examined with various inorganic or organic germanium treatments (0, 5, 10, 25, 50, 75 and 100 mg L<sup>-1</sup>), respectively. Brasica juncea C. growth did not much inhibited until Ge 10 mg L<sup>-1</sup> concentration under both Ge<sub>-</sub>132 and GeO<sub>2</sub> treatments as compared to control. On the other hand, at Ge concentration higher than 25 mg L<sup>-1</sup> concentration, Brasica juncea C. growth was inhibited under both Ge<sub>-</sub>132 and GeO<sub>2</sub> treatments. Under treatment of GeO<sub>2</sub>, length of root and shoot slightly increased until 5 mg L<sup>-1</sup> concentration and dry weight slightly increased until 10 mg L<sup>-1</sup> concentration. Under treatment of Ge<sub>-</sub>132, length of root and shoot slightly increased until 10 mg L<sup>-1</sup> concentration and dry weight slightly increased until 25 mg L<sup>-1</sup> concentration. Total Ge contents in Brasica juncea C. early seedlings with GeO<sub>2</sub> treatment were a bit higher than those with Ge<sub>-</sub>132 treatment. Germanium was primarily accumulated in the roots (77%) with organic Ge (Ge<sub>-</sub>132) treatments, whereas Ge was primarily accumulated in the leaf (70%, respectively) with GeO<sub>2</sub> treatments. The Ge uptake rates in inorganic Ge treatments were slightly high than those in organic Ge treatments. Under inorganic Ge treatment with 2.5 mg L<sup>-1</sup>, about 3% of Ge was accumulated into plant and distribution in leaf and root was 84.8% and 15.2%, respectively. Under organic Ge treatment with 2.5 mg L<sup>-1</sup>, about 2.6% of Ge was accumulated into plant and distribution in leaf and root was 66.4% and 33.6%, respectively.
