Abstract
The effects of Zn(10~100 mg·L-1) on the wheat seed germination rate, length of bud and root, activity of α-amylase, protease and catalase in the presence of Hg(15 mg·L-1) were investigated in this study. The results showed that the single treatment of Hg(15 mg·L-1) inhibited the wheat seed germination rate, the root and bud length and the activity of α amylase and catalase, while enhanced the protease activity. The addition of Zn(10~100 mg·L-1) rarely affected the seed germination rate, while reduced the suppression of root length, bud length and α amylase compared to the single treatment of Hg. This remission decreased with the increase of Zn concentration. Which indicated that a certain range of Zn could mitigate the toxicity produced by Hg on wheat seeds. 10 mg·L-1 Zn weakened the promoting function of protease activity by single Hg stress on wheat seeds and almost made it go back to the control level. However, 20~100 mg·L-1 Zn showed an inhibitory effect on the protease, which was lower than the control level, and the influence decreased with the increase of Zn concentration. The addition of Zn enhanced the inhibition of catalase activity caused by single Hg stress.
