“…In the present study, the variation may be attributed to abrupt changes in climatic conditions prevailing in the mainland of Albania. The decrease in needle resin yield from autumn to spring is also supported by other previous investigations (Guenther, 1952;Schonwitz et al, 1990). More than sixty compounds were detected and identified in the needle oleoresins of A. alba, rep resenting approximately 92-96% of the oleoresin (Table III).…”

A bies alba, O leoresin, TerpenesTerpene com position o f needle and cortical oleoresin from lateral shoots were analyzed by GC/MS for four Silver fir (A bies alba Mill.) populations scattered in natural species range in Albania. More than sixty compounds were detected in the needle oleoresin, which was characterized by a high content of a-pinene, camphene, ß-pinene, limonene and bornyl ace tate. Three m onoterpenes, a-pinene, ß-pinene and limonene, and two sesquiterpenes, ß-caryophyllene and germacrene D, comprised the majority of cortical oleoresin. The terpene composition differences among the populations that led to the recognition o f two chemotypes. The needle oleoresin from the provinces of Puka, Bulqiza and Llogara were character ised by high amounts of ß-pinene, camphene and a-pinene and low amounts of limonene, while that from D renova had high amounts of ß-pinene and limonene. A similar pattern was found in the cortical oleoresin with the exception of camphene that was a minor contributor. Geographical and seasonal variation between the populations was, also, investigated. Multi variate analysis o f both needle and cortical oleoresin separated D renova (southeastern pop ulation) from the other sites. W hen both major m onoterpenes and sesquiterpenes were con sidered four chemical profiles could be attributed. Based on their chemical profiles, the populations can be divided into two groups:• Populations with high content of ß-pinene and a-pinene but a low content of limonene (Puka, Bulqiza and Llogara), typical of most of A. alba populations in all its distribution range.• Population with a high content of limonene and a moderate content of ß-pinene and apinene (D renova).

“…Monoterpene composition is quite stable in mature needles, but the absolute amount of individual and total monoterpenes fluctuate during the seasons (Schonwitz et al, 1990), and this was also observed in our study. In the present study the greatest differences were found in the concentrations of 3-carene, a-pinene, /?-pinene + sabinene, myrcene, tricyclene and total monoterpenes between seasons.…”

S L' M M .\ R •^'Variations ol'terpenc, resin acid and total phenolic concentrutions in yuung seedlings of SiicitF. pine (Pinus sy L,) from nine different seed origins growing in three locations of different latitudes, in Finland and Kstonia, wert investigated in autumn 1991 and spring 1992. Seasonal variation uas remarkahle in monoterpene, resin acid and total phenolic concentrations. In spring there was more 3-carene, a-pinene, /^-pinene + sabinene and total monoterpenes m pine shoots, and less myrcene and tncyclerie compared to autumn. Concentrations of some individual resin acids, levopimaric and dehydroahietic acids, were higher in autumn. The total phenolic concentration vvas higher in spring. In the most northern location, the concentrations of total monoterpenes and total phenolics were lowest. The total resin acid concentration vvas highest in the middle location, and indi\idual resin acids, palustric and neoabietic acids, w ere more common in the most northern location. Seed origin had no significant effects either to the resin acid or total phenolic concentrations. There wt're almost equal concentrations of total phenolics and resin acids in northern and southern t)rigins. Instead some individual monoterpenes. limonene, tricyclene, camphene, /f-pinene + sabinene and hornylacetate, were more common in northern seed origins. The results suggest that the origin of the seed material is not so important in affecting the concentrations of secondary compounds as are the en\ ironmental factors.

“…The elevated levels of monoterpenes and sesquiterpenes after MeJA spraying peaked 15 d after treatment but declined to control levels rapidly after that, probably as a result of volatilization or catabolism. Seasonal declines of monoterpene levels in Norway spruce foliage have been noted previously (Schö nwitz et al, 1990b).…”

Induction of Volatile Terpene Biosynthesis and Diurnal Emission by Methyl Jasmonate in Foliage of Norway Spruce

Terpenoids are characteristic constitutive and inducible defense chemicals of conifers. The biochemical regulation of terpene formation, accumulation, and release from conifer needles was studied in Norway spruce [Picea abies L. (Karst)] saplings using methyl jasmonate (MeJA) to induce defensive responses without inflicting physical damage to terpene storage structures. MeJA treatment caused a 2-fold increase in monoterpene and sesquiterpene accumulation in needles without changes in terpene composition, much less than the 10- and 40-fold increases in monoterpenes and diterpenes, respectively, observed in wood tissue after MeJA treatment (D. Martin, D. Tholl, J. Gershenzon, J. Bohlmann [2002] Plant Physiol 129: 1003–1018). At the same time, MeJA triggered a 5-fold increase in total terpene emission from foliage, with a shift in composition to a blend dominated by oxygenated monoterpenes (e.g. linalool) and sesquiterpenes [e.g. (E)-β-farnesene] that also included methyl salicylate. The rate of linalool emission increased more than 100-fold and that of sesquiterpenes increased more than 30-fold. Emission of these compounds followed a pronounced diurnal rhythm with the maximum amount released during the light period. The major MeJA-induced volatile terpenes appear to be synthesized de novo after treatment, rather than being released from stored terpene pools, because they are almost completely absent from needle oleoresin and are the major products of terpene synthase activity measured after MeJA treatment. Based on precedents in other species, the induced emission of terpenes from Norway spruce foliage may have ecological and physiological significance.
