摘要：
Two genotypes of tomato A 100 and Ontario 7710 which were inoculated separately with four strains of Pseudomonas syringae pv. tomato differed significantly in disease severity (susceptibility) to bacterial speck. At both concentrations of inoculum of each strain used (10(7) and 10(8) cfu/ml) A 100 appeared to be highly susceptible whereas Ontario 7710 showed very low or no susceptibility. The significant differences in virulence between strains and in response of tomato plants in three replicate experiments were found. Generally, concentration of 10(7) cfu/ml was too low to induce consistent level of disease severity. The obtained results indicate the importance of consistent and favorable conditions for disease development in screening of tomato resistance to bacterial speck.
