| Abstract/Contents: | "An excised-leaf inoculation technique was developed to evaluate interactions of species of Exserohilum, Bipolaris, Curvularia, and Drechslera with bermudagrass. Sections of leaf blades from near growing stem tips were excised, placed on water agar, and incoluated with mycelium of pathogens at distal edges. Symptoms were evaluated accoring to the extent of necrosis that developed down the leaf sections after 5 days. Symptom severity increased in leaves progressively distal from growing stem tips. Fewer differences in virulence of pathogens were evident in excised leaf tissues than in foliage inoculated with spores. In repeated experiments, significant differences in extent of necrosis were observed among 40 randomly selected genotypes of bermudagrass when excised leaf sections were inoculated eith E. rostratum. It is suggested from these results that the excised-leaf inoculation technique may be used to identify and compare quantitative host resistance to dematiaceous hyphomycetes in individual genotypes of bermudagrass." |
