Characteristics of Organic Acid Secretion Associated with the Interaction between Burkholderia multivorans WS-FJ9 and Poplar Root System

Figure 3

Induced effect of different concentrations of IAA on the secretion of organic acids. B multivorans and poplar were cultured separately. The contents of both GA and shikimic acid among the fermentation broths of B. multivorans WS-FJ9 with different IAA concentrations added had no significant differences, and the contents of both GA and malonic acid in 0-phosphorus nutrient solution cultured poplar were increased with IAA concentration.
