The boreal forests represent 73% of the world’s coniferous forests, and they have been considered a significant natural sink of methane (CH4) and a natural source of nitrous oxide (N2O) (Dalal and Allen, 2008), important greenhouse gases naturally metabolised in soils. CH4 and N2O produced in soils can be taken up by roots, and transported into the aboveground plant tissues, either via transpiration stream in xylem, and/or via intercellular spaces and aerenchyma system (Rusch and Rennenberg, 1998; Butterbach- Bahl et al., 1997; Terazawa et al., 2007; Machacova et al., 2013a,b). The release into the atmosphere can occur via lenticels and/or stomata (Butterbach-Bahl et al., 1997). Both gases may also be formed directly in plants, either by plant’s physiological processes (Smart and Bloom, 2001; Keppler et al., 2006), or by microorganisms (Mukhin and Voronin, 2009).
