Open publisher page 0 citations

Abstract

By means of water culture method,the study was conducted to investigate the effect of Se in different concentrations on the seed germination rate and growth of seeding under Hg and Cd stress.The results showed that the detoxication effect of Se was shown while the seed germinated.The one concentration of Se suited with the one concentration of Hg and Cd concentration completely,The effect of detoxication was the strongest when the concentration of Hg and Cd came to 3mg/L,Se 1mg/L.The cell division index and the chlorophyll content were increased,and aberration rate of radical cells and activity of POD were decreased.
