Effects of Watersoaking on Response to Xanthomonas vesicatoria in Pepper Leaves

COOK, A. A., and R. E. STALL. 1977. Effects of watersoaking on response to Xanthomonas vesicatoria in pepper leaves. Phytopathology 67:1101-1103. Detached pepper leaves watersoaked after infiltration with watersoaking was permitted to dissipate from leaves kept Xanthomonas vesicatoria (XV) did not develop a watersoaked for various periods ranging from 0-6 hr after hypersensitive response (HR). Bacterial concentration in the inoculation. Patterns of bacterial multiplication and inoculum and multiplication in vivo during incubation electrolyte leakage in detached leaves kept watersoaked for resulted in bacterial populations in excess of the minimal 72 hr after infiltration inoculation with either of two concentration required to induce HR, but only a small pathotypes of XV were similar to results from susceptible increase in electrolyte leakage was detected after 24-36 hr of leaves left in situ after inoculation. incubation. Typical development of HR began 2-3 hr after
