Growth and survival of Xanthomonas campestris pv. When guttation fluids were filter sterilized, the sizes of the populations of the pathogen were not significantly reduced for at least 14 days. The sizes of populations of Xcd-lux in sterile distilled water and phosphate buffer 14 days after inoculation were 6.01 and 5.70 log CFU/ml, respectively. It was rare that more than 1.0 ml of guttation fluid was collected from one plant, and none of the cultivar ARCS and UH1060 plants produced more than 1.0 ml of guttation fluid overnight. The numbers in parentheses are the logarithms of the initial sizes of the populations of all bacteria (mean of four replicates) in guttation fluids from the cultivars. CAB Direct
