Both gases can be emitted from the surfaces of plants, especially from plants possessing an aerenchyma system. CH4 and N2O emitted from aboveground plant surfaces can be produced by soil microorganisms followed by diffusion into roots, transport within the plant and emission into the atmosphere. The plant transport is thought to proceed via intercellular spaces and the aerenchyma system, and/or through the xylem via the transpiration stream. The release into the atmosphere can run via lenticels and/or stomata (e.g. Butterbach-Bahl et al., 1997; Rusch and Rennenberg, 1998). In addition, both gases may be formed by microorganisms living inside the plant and/or by the plant itself. However, the contribution of these two sources to global emissions appears to be low. Over the last decades, N2O and CH4 emissions from plants into the atmosphere were almost exclusively studied on herbaceous species possessing an aerenchyma system (mainly rice). If trees were investigated, studies focused on species naturally living in riparian forests, which are usually well adapted to flooding (e.g. aerenchyma formation) (e.g. Rusch and Rennenberg, 1998; McBain et al., 2004; Terazawa et al., 2007; Gauci et al., 2010; Rice et al., 2010; Macháþová 2012; Machacova et al., 2013). However, to our knowledge, N2O and CH4 emissions have never been studied on coniferous tree species under field conditions.
