Abstract: Fourteen gramineous forages were stressed by different lead treatments (0, 10, 50, 100, 200, 300 mg/kg) at the seedling stage in pots. By measurement of plant height, tiller number, shoot and root biomass, antioxidant enzyme activities and shoot and root lead ion content, the effects of lead stress on growth, physiology, accumulation and transportation were analyzed. At low levels of lead exposure, plant height, tiller number and shoot biomass were generally increased, then reduced gradually with increasing lead exposure. Agropyron elongatum G₅ from Turkey was found to have a high lead tolerance. With increasing lead exposure, lead ion content in roots and shoots increased gradually, while the bio-concentration factor and transfer factor decreased gradually except for Elymus dahuricus G₇ and G₈. The content of lead ions in roots was significantly higher than that in shoots, from which we concluded that the root was the main organ by which Poaceous forages accumulate lead ions. The content of lead ions in shoots of E. dahuricus G₇ and G₈ were higher than in other germplasm, indicating a high capacity for lead accumulation and transportation. From physiological analysis of seven evaluated varieties, it was found that with increased lead exposure, proline content increased gradually, and catalase (CAT) activity decreased gradually, while peroxidase (POD) and superoxide dismutase (SOD) were elevated at low levels of exposure, but decreased at higher levels of exposure.
