The potential of a number of fluorescent pseudomonad strains to promote growth of guayule plants in the greenhouse and in the field was studied. A number of bacterial strains collected from guayule roots and rhizospheres promoted growth of greenhouse-grown plants but not field-grown plants. Percent increase in shoot dry weight of 12-week-old, greenhouseinoculated guayule plants ranged from 17 to 75 nine weeks after inoculation compared to non-inoculated plants. The increased growth of plants in the greenhouse could reduce production cost by shortening the time required to maintain plants in the nursery prior to transplanting to the field.
