Influence of stem diameter, water content, and freezing-thawing on bacterial canker development in excised stems of dormant stone fruit.

摘要: Cao, T., Sayler, R. J., DeJong, T. M., Kirkpatrick, B. C., Bostock, and Shackel, K. A. 1999. Influence of stem diameter, water content, freezing-thawing on bacterial canker development in excised stems dormant stone fruit. Phytopathology 89:962-966. In peach (Prunus persica), prune domestica), almond dulcis), hydration, influenced the extent infection caused by Pseudomonas syringae pv. syringae. Bacterial lesion length increased with increasing demonstrating need to account for effects diameter when data are analyzed. Lesion or decreased hydration dehydration, respectively. However, tissue content was not a good indicator susceptibility P. syringae, as larger had lesions lower than did smaller stems. After freezing at ‐5°C 12 24 h, inoculations made during thawing process produced significantly performed before after thawing. These results support hypothesis that is associated noninjurious fr eezing result passive spread bacteria through redistribution inoculation process. Plant relationship characteristics can influence movement may be an important component fruit trees.
