| 摘 要： | Effects of Pb^2 on the growth of mung bean(Phaseolus radiatus L.)seedlings were conducted with an experiment.The results showed that the dry weight of roots increased by 13.01%,the dry weight of shoots decreased by 12.80%,the free proline and MDA content in leaves increased specially by 2.07% and 5.82%,the activity of POD decreased by 37.32% compared to control under 0.05mmol/L Pb^2 treatment.Under 0.5mmol/L Pb^2 treatment,the dry weights of roots and shoots decreased specially be 14.45% and 29.36%,the free proline and MDA content in leaves increased specially by 43.55% and 28.50,the activity of POD decreased by 59.37% compared to control.The results indicated that Pb^2 interfered the growth of mung bean seedlings by destroying cell membrane intergrity and decreasing the activity of POD in leaves.

| Abstract: | Effects of Pb\+\{2+\} on the growth of mung bean ( Phaseolus radiatus L.) see dlings were conducted wit h an experiment. The results showed that the dry weight of roots increased by 13 . 01%, the dry weight of shoots decreased by 12.80%, the free proline and MDA cont ent in leaves increased specially by 2.07% and 5.82%, the activity of POD decrea sed by 37.32% compared to control under 0.05 mmol/L Pb\+\{2+\} treatment. Under 0.5 mmol/ L Pb\+\{2+\} treatment, the dry weights of roots and shoots decreased specially by 14. 45% and 29.36%, the free proline and MDA content in leaves increased specially b y 43.55% and 28.50%, the activity of POD decreased by 59.37% compared to control . The results indicated that Pb\+\{2+\} interfered the growth of mung bean seedl ings by destroying cell membrane intergrity and decreasing the activity of POD in leaves . |
