Abstract: The effects of different concentrations of sodium selenite on growth of Cardamine hupingshanensis were studied to explore the response of C. hupingshanensis to sodium selenite stress. The results showed that within the concentration range of 0~30 mg/L sodium selenite, the germination rate, seedling rate and root length of C. hupingshanensis plants were obviously improved, and reached the maximum at 30 mg/L sodium selenite. When the concentration of sodium selenite was higher than 50 mg/L, the rate of C. hupingshanensis etiolation seedlings increased with the increase of sodium selenite concentration. Under the treatment of 40 mg/L sodium selenite, the C. hupingshanensis plant height and growth reached the maximum. Low concentration sodium selenite significantly increased the biomass of C. hupingshanensis compared with the control. The CAT activity of C. hupingshanensis showed an overall trend of first increasing and then decreasing, and reached the highest value at 150 mg/L sodium selenite. POD activity showed a trend of first declining and then increasing, reaching the maximum value at 400 mg/L sodium selenite.
