The Correlation between Xanthomonas Oryzae Inoculum Concentration and the Size of Disease Spots in the Flag and Second Leaves
Abstract
Percentages and size of diseased spots on the flag- and the secondary-leaves lineally decreased with gradually decreasing inoculated bacterial concentrations. The diseased spots of the secondary-leaves were remarkably larger in size than those of the flag-leaves, which were found to be more resistant than the secondary-leaves regardless of bacterial concentrations. In the secondary-leaves, diseased spots could easily be formed at very low bacterial concentrations. The differences in spotted area between the flag- and the secondary-leaves were smaller in resistant varieties than in the susceptible varieties.
