“…The broad range of alkane homologues detected in A. chilensis corresponds with that reported for other members of the Cupressaceae and is in contrast to the narrower range of homologues detected in the Pinaceae (Herbin & Robins, 1968). Within this relatively wide-ranging homologous series of alkanes in the Cupressaceae, marked species differences in the dominance of certain carbon-chain lengths can be found.…”

alkanes to be dominant. Quantitatively, the chromatograms varied significantly among populations. Multivariate analyses showed that arid zone populations from mediterranean Chile and the Patagonian steppe were different from one another and were distinct from mesic populations close to the Valdivian rainforest vegetation zone. Mediterranean Chilean populations were characterized by higher concentrations of the longer carbon-chain alkanes, but retained equal amounts of shorter-chain homologues as the mesic populations. A greater variation in chain lengths and higher concentrations of longer carbon chains in the mediterranean populations is consistent with a model for the adaptation to reduced cuticular permeability. Partial Mantel matrix tests revealed significant climatic and inter-population distance effects with taxonomic distances based on multivariate and univariate hydrocarbon data. Annual rainfall was overall the most significant factor, particularly in regressions with the shorter-chain hydrocarbons. Annual mean temperature was most significant for the longer-chain hydrocarbons. This suggests, on the one hand, ecogenic adaptation to both temperature and precipitation of cuticular hydrocarbon composition, and, on the other hand, a weaker, but important effect of gene flow in determining hydrocarbon composition in this species. The northernmost populations at San Felipe and San Gabriel were the most distinctive. This could result from the effects of random changes in allele frequencies and\or to founder effects in isolated and small populations. These populations show some East-Andean affinities presumably due to historic migration patterns.

This is the first report of population variability of the contents of n-alkanes and nonacosan-10-ol in the needle epicuticular waxes of Serbian spruce (Picea omorika). The hexane extracts of needle samples originated from three natural populations in Serbia (Vranjak, Zmajevački potok, and Mileševka Canyon) were investigated by GC and GC/MS analyses. The amount of nonacosan-10-ol varied individually from 50.05 to 74.42% (65.74% in average), but the differences between the three investigated populations were not statistically confirmed. The results exhibited variability of the composition of n-alkanes in the epicuticular waxes with their size ranging from C(18) to C(35). The most abundant n-alkanes were C(29), C(31), and C(27) (35.22, 13.77, and 12.28% in average, resp.). The carbon preference index of all the n-alkanes (CPI(total)) of the P. omorika populations (average of populations I-III) ranged from 3.3 to 11.5 (mean of 5.9), while the average chain length (ACL) ranged from 26.6 to 29.2. The principal component and cluster analyses of the contents of nine n-alkanes showed the greatest difference for the population growing in the Mileševka Canyon. The obtained results were compared with previous literature data given for other Picea species, and this comparison was briefly discussed.

“…The "epicuticular waxes" from gymnosperms have been extensively studied [13][14][15][16][17]. A comparison of our observations with those of G iinthardt [18] and G ünthardt and W anner [12] on Picea and Pinus nee dles is of relevance.…”

“…A comparison of our observations with those of G iinthardt [18] and G ünthardt and W anner [12] on Picea and Pinus nee dles is of relevance. Pollen waxes contain no second ary alcohols, such as non-acosan-10-ol, which are typical for almost all gymnosperm needle waxes [14][15][16]. An unexpected observation was the high content of unsaturated fatty acids with chain lengths of C 16-C 20.…”

Pinus m ugo T urra, Pinaceae. Pollen, Wings, Localization of Epicuticular Waxes "Epicuticular waxes" from pine pollen and from pollen wings have been investigated. Various hydrocarbons, aldehydes, wax esters, free fatty acids and primary alcohols in the form of homologous series were identified. A noteworthy observation was the presence of a large num ber of unsaturated fatty acids.A lthough there were quantitative differences between the waxes from whole pollen and pollen wings, the distribution patterns of chain lengths of the individual compounds were very similar.It is dem onstrated unequivocally, through the use of pollen wing m aterial, that the waxes are com ponents of the exine. It is postulated that the pollen waxes provide an additional effective mechanism for protection against the effects of the physical and chemical environm ent.
