Notes
Blue grama (Bouteloua gracilis (H.B.K.) Griffiths) was grown in gonotobiotic plant microcosms inoculated with Pseudomonas paucimobilis and with or without the plant ectoparasitics nematode Tylenchorhynchus claytoni. Plant inoculated with T. claytoni had less root biomass than controls on each of the four sample dates but this was not significant (p<0.05). Shoot biomass, however, was significantly less with nematodes, on the final sample date. Significantly higher bacterial populations were found in the treatment with nematodes in both rhizosphere and nonrhizosphere soil. Soil and plant N and P concentrations were not changed by addition of ectoparasitic nematodes.
