Abstract

The effects of germanium dioxide (GeO2) and 2-carboxyethyl germanium sesquioxide (Ge-132) treatments on cucumber (Cucumis sativus L.) growth and Ge accumulation and toxicity were investigated. Accumulated Ge contents in plant treated with GeO2 were two times greater than that in plants treated with Ge-132. Germanium accumulated primarily in the shoots in the GeO2 treatments and in the roots in the Ge-132 treatments. In contrast GeO2 was easily transported from roots to shoots. In cucumber fruit, the range of Ge content in both the GeO2 and Ge-132 treatments was in the order of stalk > rind > pulp > seeds, suggesting that Ge accumulation was based on distance from xylem. Silicon (Si) content significantly decreased as GeO2 concentration increased, but there was no difference in Si content in the Ge-132 treatment. Therefore, plant growth and Ge accumulation are affected differently by GeO2 and Ge-132 treatments, based partly on treatment concentrations.
