Field monoterpene emission of Mediterranean oak (Quercus ilex) in the central Iberian Peninsula measured by enclosure and micrometeorological techniques: Observation of drought stress effect

Abstract: [1] An experimental characterization of biogenic emission from Quercus ilex ssp. rotundifolia in a forest near Madrid, Spain, was carried out in the early autumn of the years [2000][2001][2002][2003]. A dynamic branch enclosure technique was implemented to determine the monoterpene emission rates of this evergreen oak species during the 2000 and 2001 campaigns. Major compounds emitted during both measurement periods were limonene, a-pinene, b-pinene, sabinene, and myrcene. In the 2000 field campaign the light-… Show more

“…The higher terpene emission rates in summer than in spring were also explained mostly by a large change in emission factor (capacity). Q. ilex is a strong emitter of terpenes, especially in warm summer conditions (Staudt and Seufert, 1995;Kesselmeier et al, 1996;Street et al, 1997;Holzinger et al, 2000;Llusia and Peñuelas, 2000;Loreto et al, 2001;Owen et al, 2001;Staudt et al, 2002;Plaza et al, 2005;Llusia et al, 2011). The Q. ilex monoterpene emission rates were 6.4 (3.7 for standardised values) times higher in summer than in spring, similar to reports of Llusia et al (2011) in a atypically warm and dry summer.…”

“…Strong, long-lasting drought, however, decreases isoprenoid emissions considerably (Hansen et al, 1999;Pegoraro et al, 2004, Lavoir et al, 2009. Overall, an impact of summer drought on annual isoprenoid emission has frequently been observed (Geron et al, 1997;Plaza et al, 2005). A mechanistic understanding of isoprenoid responses to drought stress, however, has not yet been established.…”

“…Additional effects on C-cycling and emissions of biogenic volatile organic compounds Drought usually increases emissions of plant terpenes, although this effect strongly depends on drought intensity (Pegoraro et al 2005;Plaza et al 2005;Llusia et al 2006Llusia et al , 2008Llusia et al , 2010. Studies suggest that severe drought decreases the emission of terpenes (Loreto et al 2001;Pegoraro et al 2007;Peñuelas and Staudt 2010) but reduces sink strength of the soil for atmospheric isoprene (Pegoraro et al 2007).…”
