Presentation Abstract
The ability of weed deleterious rhizobacteria to reduce plant growth is dependent on the production of bacterial factors such as cyanide and plant hormones. Bacteria utilize amino acids to produce these factors: tryptophan for indole acetic acid production and glycine for cyanide production. The goal of this project is to manipulate rhizosphere conditions to favor the action of rhizobacteria in suppressing weeds. This work will test for the effect of combined strains in the presence of various amino acid amendments on velvetleaf growth in soil. Specifically a cyanogenic strain Pseudomonas putida (ATH-1RI/9) will be combined with Rhizobium rubi AT3-4RS/6 (which produces an IAA-like compound). The goal is to assess if combinations of bacteria (with & without amino acids) perform better in reducing weed growth than the use of single bacterial strains.
