Research Abstract |
The aim of this study was to measure radial oxygen loss (ROL) from mangrove plant roots and to clarify soil chemical properties in the oxygen supplied rhizosphere. We observed that ROL of mangrove plants were significantly higher under illuminated conditions compared with those under dark condition. Furthermore, we detected deposition of iron oxide on root surfaces, lowered methane concentrations and increased oxidized inorganic nitrogen concentrations in the soil pore water, suggesting that ROL had affected theses soil chemical properties.
