Paddy fields are major sources of global atmospheric greenhouse gases, including methane (CH4) and nitrous oxide (N2O). The different phases previous to emission (production, transport, diffusion, dissolution in pore water and ebullition) despite well-established have rarely been measured in field conditions. We examined them and their relationships with temperature, soil traits and plant biomass in a paddy field in Fujian, southeastern China. CH4 emission was positively correlated with CH4 production, plant-mediated transport, ebullition, diffusion, and concentration of dissolved CH4 in porewater and negatively correlated with sulfate concentration, suggesting the potential use of sulfate fertilizers to mitigate CH4 release. Air temperature and humidity, plant stem biomass, and concentrations of soil sulfate, available N, and DOC together accounted for 92% of the variance in CH4 emission, and Eh, pH, and the concentrations of available N and Fe3+, leaf biomass, and air temperature 95% of the N2O emission. Given the positive correlations between CH4 emission and DOC content and plant biomass, reduce the addition of a carbon substrate such as straw and the development of smaller but higher yielding rice genotypes could be viable options for reducing the release of greenhouse gases from paddy fields to the atmosphere.

“…This was consistent with the report of neue and Roger (1993), who found large differences in methane emissions due to different root oxidizing power among rice cultivars. In fact, root exudates constitute an organic substrate for microbial organisms that could be utilized for methane production and oxidation by methanogens and methanotrophs, respectively (Win et al 2012). Frenzel et al (1992) reported that 80-90% of the methane produced in the rhizosphere was re-oxidized.…”

“…Of the total methane emitted from a rice field during the growing season, 60-90% is transported through the rice plants rather than through molecular diffusion across water-air interfaces or through the release of gas bubbles (Holzapfel-Pschorn et al 1986;Schütz et al 1989;. Rice plant have three key functions regulating the methane budget (Setyanto et al 2004;Zheng et al 2013): (1) as a source of methanogenic substrate through root exudates and/or dead root cells Kerdchoechuen 2005); (2) as a channel for methane through well-developed intercellular air spaces (aerenchyma) in leaf blades, leaf sheaths, culms and roots of rice plants, which provide an effective channel for gas exchange (methane transport capacity (MTC)) between the atmosphere and the anaerobic soil (Raskin & Kende 1985;Butterbach-Bahl et al 1997;Shao & Li 1997;Aulakh et al 2000;Fu et al 2007);and (3) as an active methane oxidizing site in the rice rhizosphere by supporting oxygen counter transport through the aerenchyma system (Win et al 2012;Gutierrez et al 2014).…”

Irrigated rice, represents a methane (CH4) emissions source. In rice fields, the dominance of plant-mediated transportation of CH4 from submerged soils to the atmosphere raises the possibility of varietal differences in CH4 emissions. Previous findings remain inconclusive and no study has explored varietal differences in CH4 emissions of rice in Latin America. A field experiment was conducted in Colombia to investigate the potential of a breeding line, a commercial variety, and two rice hybrids to mitigate CH4 emissions from irrigated rice. Data on CH4 emissions, phenotypic, physiological, root traits, and grain yield were collected. Results showed CH4 emissions, grain yield, root length and root surface area differences followed the order Hybrid 2 > Hybrid 1 > breeding line > Commercial variety. Whereas CH4 emissions per unit area for the two rice hybrids were within the of range 29–62% higher than the commercial variety and breeding line, CH4 emission per unit grain yield were similar across the rice genotypes. Our data suggests that differences in root development and grain yields explain genetic influence on CH4 emissions. We conclude that by exploiting differences in productivity and root characteristics among rice cultivars the transition towards low emission rice production systems can be accelerated.
