Frequency, distribution, and characteristics of endophytic Pseudomonas syringae in pear trees

1991-04-01

Abstract excerpt

Internal stem and root tissues of pear trees were sampled for presence of Pseudomonas syringae at seven orchards in Oregon. Isolates positive for fluorescence (F+) and negative for cytochrome oxidase reaction (Ox-) were defined as P. syringae. Endophytic F+ Ox- strains occurred in 84% (57/68) of the trees. Eighty-one percent (191/235) of the F+ endophytic stains were Ox-. A total of 159 and 32 P. syringae strains...
