| Abstract/Contents: | "High subpopulations of Pseudomonas syringae were detected from naturally occurring grass species on the edges of nursery production areas and from sudangrass and cereal ryegrass used as green manure and cover crops, respectively. Leaf samples obtained from diseased sudangrass and symptomless cereal ryegrass and roadside grass species in November yielded large populations of pathogenic and ice-nucleation-active strains of P. syringae. Populations approaching 10(9) cfu/g of fresh tissue were isolated from sudangrass samples, whereas populations of 10(6) cfu/g were obtained from ryegrass and roadside grass samples. Of 81 randomly selected strains from these isolations tested, 58 (72%) were similar to P. syringae; of these, 34 (59%) were ice-nucleation-active at -5 C. Thirty-one of the P. syringae strains (54%) induced a hypersensitive response in tobacco leaves and 29 (50%) were pathogenic on green fruit of yellow pear tomato." |
