The effect of rhizosphere oxidation on redox level was investigated between vegetated and denuded plots and betweenAcer rubrum andFraxinus pennsylvanica seedlings within a seasonally flooded forested system in Virginia. Redox potentials were significantly greater (p<0.05) in the upper 15 cm of the soils in the vegetated plots. Redox potential within the root mass ofAcer rubrum seedlings did not differ significantly from those adjacent to the root mass.Fraxinus pennsylvanica seedlings showed significantly p < 0.01) elevated redox potential within the root mass when compared to the adjacent nonrooted area. Vegetation directly influences the redox state of the rhizosphere in seasonally flooded forested systems through seasonal growth patterns and adventitious root formation. This may have implications in the biogeochemical cycling of soil constituents in forested wetland systems and subsequent water quality functions.
