Abstract

To investigate the effect of inorganic () and organic (Ge-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 ), respectively. Brasica juncea C. growth did not much inhibited until Ge concentration under both Ge-132 and treatments as compared to control. On the other hand, at Ge concentration higher than concentration, Brasica juncea C. growth was inhibited under both Ge-132 and treatments. Under treatment of , length of root and shoot slightly increased until concentration and dry weight slightly increased until concentration. Under treatment of Ge-132, length of root and shoot slightly increased until concentration and dry weight slightly increased until concentration. Total Ge contents in Brasica juncea C. early seedlings with treatment were a bit higher than those with Ge-132 treatment. Germanium was primarily accumulated in the roots (77%) with organic Ge (Ge-132) treatments, whereas Ge was primarily accumulated in the leaf (70%, respectively) with treatments. The Ge uptake rates in inorganic Ge treatments were slightly high than those in organic Ge treatments. Under inorganic Ge treatment with , 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 , about 2.6% of Ge was accumulated into plant and distribution in leaf and root was 66.4% and 33.6%, respectively.
