Rice ch4
WebbOxidation of CH 4 in the rhizosphere of rice plants was quantified using (1) methyl fluoride, a specific inhibitor of CH 4 oxidation, and (2) measuring changes in plant-mediated CH 4 emission after incubation under air, N 2, or 40% O 2. No significant rhizospheric CH 4 oxidation was observed from rice plants in the ripening stage.
