Abstract
The effects of Cr6+ on seed germination and growth of cabbage,maize and mustard were studied in this paper.The results showed that: there had different effects of Cr6+ on different seeds,and different effects with different concentrations of Cr6+ on the same seed.Cr6+ Severely inhibited cabbage seed germination and growth.It promoted mustard seed germination and growth with concentration less than 250 mg·L-1,200 mg·L-1 respectively,but it inhibited mustard seed germination and growth with concentration larger than 250 mg·L-1,200 mg·L-1 respectively.When Cr6+ was less than 400 mg·L-1,it promoted maize seed germination.Cr6+ Inhibited the growth of maize.
