摘要：

A rifampicin-resistant derivative of Pseudomonas fluorescens strain 2-79 (Pf2-79r) inhibited teliospore germination of Tilletia laevis. A rifampicin-resistant derivative of a spontaneous mutant of strain 2-79 deficient in phenazine-1-carboxylic acid production (2-79PCA-r) had no effect on germination of T. laevis. Inhibition of germination by Pf2-79r was not overcome by supplementing culture media with iron. Common bunt incidence was reduced by 65 and 50% during consecutive seasons when wheat seeds and 2-wk-old seedlings were treated with Pf2-79r. Similar treatment of seeds and seedlings with 2-79PCA-r afforded no protection against common bunt.
