| Abstract/Contents: | "Forty-eight cool-season grasses in eight different genera were tested for their tolerance to the causal agent of rapid blight, Labyrinthula sp. Seeds of each test grass were sown in 7.6-cm pots and placed in a growth chamber for approximately three weeks at 23.8°C with 12 hours daylight and 12 hours darkness. Plants were watered until saturation every other day with deionized water for the first two weeks of growth, then with artificial sea water at a concentration of 3.5 deciSiemens per meter (dS/m). Inoculum was prepared by growing six isolates on 1% horse serum agar for four days, adding colonized agar plugs to 1% horse serum broth and vortexing. Cell counts of 1.0-1.5 ^D#x 105 per ml were used each time for inoculations. Experimental design was a split plot with four reps where each pot was an experimental unit and the experiment was repeated. Plants in each pot were wounded by trimming with scissors prior to the application of 1ml of inoculum placed on leaf tissue in the form of droplets from a syringe. Disease severity was evaluated at 14 and 21 days post-inoculation. Results indicate a high degree of susceptibility in cultivars of rough bluegrass, colonial and velvet bentgrasses, and perennial ryegrass while certain cultivars of alkaligrass, creeping red fescue, and creeping bentgrass appear to have levels of tolerance." |
