Experiments were conducted for testing root tensile strength and measuring root cellulose content of Medicago sativa and Digitaria sanguinalis. Results indicated that in the two species, both the tensile strength and percentage of cellulose were negatively correlated with root diameter, while a positive correlation was found between percentage of cellulose and tensile strength. The conclusion confirmed that the relationship among root tensile strength, root diameter and root cellulose content found in tree root system was held also in the two species.

The result showed that Imperata cylindrical, Digitaria sanguinalis, Erigeron acer Xanthium sibiricum and Hedyotis auricularia are the species with high tolerance to heavy metal pollutions adapted to the adverse conditions of wastelands. These species can be used as pioneer plants for recovety of the vegetation in the manganese-mined wastelands. The individual event pollution index of the heavy mentals, compared to their background values are higher than 2, with Pb as an exception, indicating that the soil in these areas has been contaminated and that Mn and Cd are the elements creating most serious pollution problems.
