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.
