Soil Reduction Capacity Effects on Carbon Assimilation and Radial Oxygen Loss

4 Soil Reduction Capacity Effects on Carbon Assimilation and Radial Oxygen Loss 

FIGURE 7.36 Relationship of soil redox potential to total uptake (whole plant) and leaf uptake in cherrybark oak and overcup oak. (From DeLaune et al., 1998.) 

FIGURE 7.37 Phosphorus uptake by Typha. Change in phosphorus concentration in nutrient solution maintained under oxidized, moderately reduced, and highly reduced conditions. (From DeLaune et al., 1990.) 

FIGURE 7.38 Radial oxygen loss (ROL) in Spartina patens grown nnder various soil reduction capacities while the reduction intensity was maintained at -200 mV. Values followed by the same letter are not significantly different at the 0.05 level. (From Kludze and DeLaune, 1995b.) 

Wetland plants are important in regulating the biogeochemical cycles in wetlands. The distribution and productivity of plants in wetlands are governed by both soil condition and individual plant adaptation for growing in wetland environment.
