“…Aromatic esters have earlier been identified in the scent of spruce flowers (Borg-Karlson et al 1985) which might indicate the presence of functionally similar enzymes both during stress responses and flowering. The emission of methyl benzoate, benzylalcohol, benzyl acetate and benzoic acid in the needles of N. haarlovi infested grafts could be explained by their biosynthesis occurring in parallel with the general phenylpropanoid pathway and their derivation from transcinnamic acid identified in the needles of conifers (Lebedeva et al 1982;Dudareva et al 2006;Isidorov et al Infested clones Fig. 6 Enantiomeric composition (mean ± SD) of apinene, b-pinene and limonene released upon piercing the stem of healthy and N. haarlovi infested spruces.…”

The emissions of spruce grafts (Picea abies), caused by infestation of an acarid species of the genus Nalepella were investigated. Volatiles of three clones, both healthy and infested, with different susceptibility to the large pine weevil Hylobius abietis were collected by solid phase micro extraction (SPME) and analyzed by gas chromatograph coupled to mass-spectrometry (GC-MS). In addition, enantiomers of the main chiral compounds were separated by a two dimensional-gas chromatograph (2D-GC). In the characteristic flower-like fragrances emitted by the infested grafts large amounts of E-b-farnesene, E,E-afarnesene, (-)-linalool, methyl salicylate and minute amounts of benzyl alcohol, E-anethole, methyl benzoate, neral and geranial were found. All together, these compounds could explain the characteristic scent emitted by the infested seedlings. Large differences in the emissions of Eb-farnesene, E,E-a-farnesene and methyl salicylate were found between but not within the clones.
