Leaf Damage in Cool-season Grasses Subjected to Simulated Hoof Pressures
P. W. Bartholomew and R. D. Williams
Although grazing animals may potentially damage grass tissues, few reported estimates of susceptibility of different species or cultivars to trampling exist, and no standard method of leaf tissue damage measurement has been established. This study's objectives were to evaluate electrolyte leakage and chlorophyll fluorescence as methods of quantifying tissue damage, to determine if differences in tissue damage may be identified over a range of pressure treatments, and to determine if tissue damage is different among forage species or among varieties within species.
