Mechanism by which noninhibitory concentrations of glucose increase inhibitory activity ofp-coumaric acid on morning-glory seedling biomass accumulation

Noninhibitory levels of glucose-C [≤ 72 µg carbon (C)/g soil] increased the inhibitory activity ofp-coumaric acid on morning-glory seedling biomass accumulation in Cecil B_t-horizon soil. The amount ofp-coumaric acid required for a given level of inhibition of shoot and seedling biomass accumulation decreased as the concentration of glucose increased. Soil extractions with neutral EDTA (0.25 M, pH 7) after addition of combinations ofp-coumaric acid and glucose (concentrations ranging from 0 to 1.25 µmol/g soil) to the soil showed that utilization ofp-coumaric acid by microbes decreased linearly as the concentration of glucose increased. The increased inhibitory activity of a given concentration ofp-coumaric acid in the presence of glucose was not due to a reduction in soil sorption ofp-coumaric acid or effects of nitrogen-limited microbial growth. Noninhibitory levels of phenylalanine andp-hydroxybenzoic acid slowed the utilization ofp-coumaric acid by microbes in a similar manner as glucose. The presence of methionine, however, did not affect the rate ofp-coumaric acid utilization by microbes. These observations suggest that differential utilization of individual molecules in organic mixtures by soil microbes can modify, and in this case increase, the effectiveness of a given concentration of an inhibitor such asp-coumaric acid on the inhibition of seedling growth such as morning-glory.
