Abstract
Synopsis: Significant leaf tensile‐strength differences were found among strains of weeping lovegrass and among clones of bermudagrass, sideoats grama, and sand bluestem. Wide within‐strain variations (leaf to leaf and plant to plant) made precise comparisons difficult. Reasons for this variation were investigated and procedures for increasing precisions of estimate are discussed. Principal source of nongenetic variations was age or growth stage of individual leaves tested.
