“…There are also many low or moderate negative correlations between monoterpenes and diterpenes (data not shown). Strong correlations between two monoterpenes, α-pinene and camphene, were also found by Sjödin et al (2000) in Norway Spruce and Fäldt et al (2001) in six Pinus species (not including P. halepensis). Hiltunen and Laakso (1995) and Wise and Croteau (1999) suggested that these strong correlations might indicate a common precursor.…”

High vs. low yielding oleoresin Pinus halepensis Mill. trees GC terpenoids profiling as diagnostic tool

Abstract• A discriminant study based on samples taken from high and low yielding oleoresin trees of two Greek populations, Chalkidiki and Euboia, was carried out. Oleoresin of Pinus halepensis Mill. was characterised by GC/MS analysis.• The objectives of this study were: (i) to identify in detail the composition of the oleoresin of P. halepensis and in particular of high yielding trees (plus trees) (ii) to investigate a potential relationship between the oleoresin compounds and the oleoresin yield and (iii) to investigate any correlations among the compounds.• About forty monoterpenes, sesquiterpenes and diterpenes were identified as main compounds representing 97.40% of the analyzed oleoresin. α-Pinene, methyl abietate, abietic acid, palustric acid, isopimaric acid and neoabietic acid were the major compounds. Efficient discrimination was achieved between the two populations and between the two groups of trees (high and low yielding). In both cases, the differentiation was due to the quantitative variability of certain compounds. High positive correlations were found among certain compounds.• The results suggest that the oleoresin profile is a useful tool for the discrimination of trees according to their provenance or their oleoresin yield.

“…Hiltunen and Laakso (1995) and Wise and Croteau (1999) suggested that these strong correlations might indicate a common precursor. On the other hand, Fäldt et al (2001) reported a strong correlation between α-and β-pinene which was not found in the present analysis of P. halepensis.…”

“…However, previous enantiomeric analyses of individual tree xylem have shown highly variable enantiomeric ratios from 90% (−)-α-pinene to 80% (+)-α-pinene, even from different parts of the same tree (Norin, 1996;Fäldt et al, 2001). In contrast, the spatially and temporally more extensive ecosystem scale data presented here shows a clear enantiomeric predominance in ambient air, so what could be the underlying reason for the clear dominance of the (+)-form of α-pinene over the Boreal forest and the (−)-form in air over the rainforest?…”

Mirror image hydrocarbons from Tropical and Boreal forests

Abstract. Monoterpenes, emitted in large quantities by trees to attract pollinators and repel herbivores, can exist in mirror image forms called enantiomers. In this study such enantiomeric pairs have been measured in ambient air over extensive forest ecosystems in South America and northern Europe. For the dominant monoterpene, α-pinene, the (−)-form was measured in large excess over the (+)-form over the Tropical rainforest, whereas the reverse was observed over the Boreal forest. Interestingly, over the Tropical forest (−)-α-pinene did not correlate with its own enantiomer, but correlated well with isoprene. The results indicate a remarkable ecosystem scale enantiomeric fingerprint and a nexus between the biosphere and atmosphere.

“…Among the most important volatile compounds emitted from boreal coniferous forests are monoterpenes and sesquiterpenes, which form a major proportion of the conifer oleoresin (Fäldt et al, 2001) and contribute to the constitutive emissions from trunks, needles and roots. The oleoresin is formed in e.g.…”

Chemodiversity of a Scots pine stand and implications for terpene air concentrations

Abstract. Atmospheric chemistry in background areas is strongly influenced by natural vegetation. Coniferous forests are known to produce large quantities of volatile vapors, especially terpenes. These compounds are reactive in the atmosphere, and contribute to the formation and growth of atmospheric new particles.Our aim was to analyze the variability of mono-and sesquiterpene emissions between Scots pine trees, in order to clarify the potential errors caused by using emission data obtained from only a few trees in atmospheric chemistry models. We also aimed at testing if stand history and seed origin has an influence on the chemotypic diversity. The inherited, chemotypic variability in mono-and sesquiterpene emission was studied in a seemingly homogeneous 48 yr-old stand in Southern Finland, where two areas differing in their stand regeneration history could be distinguished. Sampling was conducted in August 2009. Terpene concentrations in the air had been measured at the same site for seven years prior to branch sampling for chemotypes.Two main compounds, α-pinene and 3 -carene formed together 40-97 % of the monoterpene proportions in both the branch emissions and in the air concentrations. The data showed a bimodal distribution in emission composition, in particular in 3 -carene emission within the studied population. 10 % of the trees emitted mainly α-pinene and no 3 -carene at all, whereas 20 % of the trees where characterized as high 3 -carene emitters ( 3 -carene forming >80 % of total emitted monoterpene spectrum). An intermediate group of trees emitted equal amounts of both α-pinene and 3 -carene. The emission pattern of trees at the area established using seeding as the artificial regeneration method differed from the naturally regenerated or planted trees, being mainly high 3 -carene emitters. Some differences were also seen in e.g. camphene and limonene emissions between chemotypes, but sesquiterpene emissions did not differ significantly between trees. The atmospheric concentrations at the site were found to reflect the species and/or chemodiversity rather than the emissions measured from any single tree, and were strongly dominated by α-pinene. We also tested the effect of chemodiversity on modeled monoterpene concentrations at the site and found out that since it significantly influences the distributions and hence the chemical reactions in the atmosphere, it should be taken into account in atmospheric modeling.
