| Research Abstract |
The aim of this study was to clarify spatial dynamics of soil nitrogen fixation around mangrove plant roots. We observed that soil nitrogen fixing activity (nitrogenaze activity) was significantly higher in mangrove root zone compared with that in no root zone. This tendency was getting clear in accordance with progress of plant growth stage. Furthermore, we found that activation energy of nitrogen fixing reaction was significantly higher in mangrove root zone than in no root zone. These results lead to interpretations that mangrove plants gather nitrogen fixers around their roots and the enzymes participating in nitrogen fixation around mangrove roots are different from those in no root zone.
