“…It is possible that a high stomatal density is advantageous for Canary Island pines growing in harsh environments, by facilitating a higher leaf gas interchange in short favourable periods and consequently maximizing biomass production under environmental constraints (Wang et al 1995;Al Afas et al 2007). Both shorter needles and a higher stomatal density agree with the results found in other Mediterranean pines in natural populations: P. brutia (Dangasuk and Panetsos 2004), P. pinaster (Wahid et al 2006) and in provenance trials of P. halepensis (Calamassi 1986) and P. brutia (Calamassi et al 1988).…”

“…In conclusion, needle phenotypic traits evaluated in P. canariensis showed significant differences both among climate types and populations within the same climate type that suggest some ecotypic differentiation rather than the clinal variation observed in natural populations of other Mediterranean pines (Dangasuk and Panetsos 2004;Wahid et al 2006). Moreover, the adaptive interpretation of each particular trait is nontrivial.…”

Pine needles reflect some of the most outstanding xeromorphic characteristics of sclerophyllous plants. Detailed descriptive studies about their anatomy and morphology were carried out since the beginning of the past century but the role the different tissues play in adaptation to diverse environments is still little known. In this work we analyzed morphological and anatomical needle traits of seventeen natural populations of Pinus canariensis Chr. Sm. Ex DC to identify adaptive traits related to drought resistance and determine their variability throughout a wide range of ecological conditions. A Principal Component Analysis revealed two groups of traits, one related to drought adaptation: maximizing gas exchange, avoiding water loss and storing water and the other to photosynthesis. Results support a predominantly mechanical function of hypodermis and a possible role of transfusion tissue to withstand dry conditions, thanks to its water storing capacity. The inversion of the patterns of the relative area of the dermal and transfusion tissues in the xeric region was justified due to the influence of the extreme dry Saharan wind from the East. A clear adaptation of Pinus canariensis needles to contrasted environments is evidenced suggesting distinct phenotypic needle features in the most xeric stands.

“…Accordingly, this could be regarded as a sign of altitudinal adaptation, or it might be due to common geographical origin. However, similar findings were described in Pinus brutia by Dangasuk and Panetsos (2004), who reported the number of resin canals as a useful trait for identifying altitudinal and longitudinal adaptation variations within and among populations.…”

“…Nevertheless, cone size and weight can be influenced by tree age, general health of the trees, and the macro-and micro-habitat of the parent trees (Dangasuk & Panetsos, 2004). The high levels of variation observed in cone morphology might be explained by the long-term adaptation of populations to diverse and changing environmental conditions, and they also can be due to the lack of competition with other pines (Gil et al, 2002).…”

Carpathian Scots pine populations having peripheral distribution within the species' range are often sustained in specific types of habitats, such as peat bogs and rocky surfaces or lime consisting sandy substrates. Due to their long time adaptive processes, which involve genotypes that can be preadapted to a given selection pressure, historically isolated populations are subjects of particular interest in studies of in situ adaptation. In this study we focus on detecting the level of phenotypic differentiation based on cone morphology and needle anatomy in marginal populations of Pinus sylvestris L. in the Pannonian Basin and the Carpathian Mountains. Six cone morphological and eight needle anatomical characters were measured and four cone morphological and four needle anatomical ratios were calculated. Our results in concordance with paleobotanical data indicate a common origin of the populations from the Northern Carpathians and the Pannonian Basin. High levels of variation were observed in cone morphology. Discriminant function analysis based on the eight cone characteristics revealed clearly discernible groups of populations and indicated significant differentiation among populations growing in peat bogs and on rocky substrates. Significant differences among populations from different habitats were also revealed by comparing needle anatomical variables. The phenotypic differentiation by habitat type based on the measured characters might be evaluated as a sign of local adaptation with detectable phenotypic patterns.

“…Isik (1986), Isik and Kara (1997), and Kara et al, (1997) reported that most of these variations seem to be a function of altitude and associated climatic factors in the Taurus Mountains. Altitudinal and longitudinal variations have also been shown by Dangasuk and Panetsos (2004) on some morphological traits of the species on Crete Island, Greece. Gonzalez-Martinez et al, (2002) indicate that environmental heterogeneity and genotypeby-environment interactions seem to have a major role in quantitative differentiation when gene flow is high.…”

Turkish Red Pine (Pinus brutia Ten.) is an important forest tree species in Turkey for various economic and ecological reasons. In this study, nine RAPD (Randomly Amplified Polymorphic DNA) primers were used to determine genetic variation within and among populations of P. brutia located at the Duzlercami common-garden test site. This site was established in 1979 and includes six natural populations of P. brutia from two altitudinal transects extending from the coast to higher elevations in the Antalya region of Turkey. A total of 32 polymorphic RAPD loci were found in the analyzed six populations. The mean proportion of polymorphic loci among population samples equals 100%, mean number of alleles for each locus = 2.0, effective allele number = 1.71, Shannon's information index = 0.58, and mean Nei (1973)'s gene diversity value = 0.4. According to G ST results, a high proportion of genetic diversity (95-99%) is found within populations. A relatively high genetic differentiation was found among altitudinal population pairs in both transect. Also, data on quantitative traits (total height and/or diameter) at different ages (13, 17, 30 years) were compared with molecular data. There are similarities between the results obtained from RAPD markers and those obtained from the quantitative traits. The differentiation in quantitative traits appears to be due to local adaptation of populations. Data suggest that priority should be given to the selection of material based on geographic origin along the altitudinal gradients of P. brutia populations to conserve the genetic resource of species.
