| 英文摘要 | It has been proposed that organic acid and nonprotein thiol are involved in the hyperaccumulation of metals. In this study, Cd accumulation, organic acid, and nonprotein thiol production and their relationships in the leaves of Cd-hyperaccumulator Rorippa globosa were examined and compared with a closely related species, Rorippa islandica. The results showed that there was no reduction in biomass of R. globosa when treated with 25 mu g Cd g(-1) (T-2), despite Cd accumulation in the leaves was up to 158.2 mu g g(-1) DW. On the other hand, the growth of Cd-treated R. islandica was obviously inhibited as it accumulated more than 100 mu g g(-1) DW in the leaves. Therefore, R. islandica behaved as a Cd-accumulating plant. The Cd treatments could significantly induce the synthesis of acetic acid in both species, suggesting that acetic acid, as the most abundant organic acid, might be related to the Cd accumulation. Significant positive correlations between Cd concentrations and both tartaric and malic acid concentrations in the leaves of R. globosa were observed. There was a significant positive correlation between Cd concentrations and acetic acid concentrations in the leaves of R. islandica. This trend of tartaric and malic acids in the leaves of R. globosa and acetic acid in the leaves of R. islandica might be related to Cd accumulation. In addition, a quadratic relationship was obviously observed for NP-SH contents and total Cd concentrations in the leaves of R. globosa, indicating that NP-SH was significantly related to Cd accumulation and tolerance. |
