A morphometric and chemosystematic study on theAbiesMiller (Fir) species in Turkey

Abstract

lnfrageneric states and chemosystematic relationships are discussed by using some selected essential oil components and morphometrical characters. Morphologic and morphometric analysis are carried out on 20 Abies population and essential oil analysis on the twig with needle are carried out by using GC. techniques. The qualitative major constituents are found as same in the whole studied species but their quantitative content varies significantly. Inter and intrapopulational variations are found at the high ratio in the Abies taxa. The results are presented in graphical form, allowing patterns of variable intercorrelations and compared with phylogenetic patterns. Tree to tree variation of quantitative terpene composition of the leaf oil is sufficiently to permit chemosystematic discussions and understanding evolutionary phenomenon in the light of literatures.

Taxonomic position of Abies equi-trojani on the basis of needlecharacters by comparison with different fir species

“…Five needles from every tree were analyzed morphologically, and another five were used to prepare cross-sections for taking anatomical measurements. The set of characters used, as well as the methods of preparation and measurement, were adopted from investigations of the West Mediterranean (Sękiewicz et al, 2013) and Turkish firs (Bagci and Babaç, 2003;Boratyńska et al, 2015) after verification of their usefulness. Finally, 26 main and 13 estimated characters were analyzed (Table 2; Figure 1).…”

“…These characters were also used in a comparative study between the Abies species that occur in Turkey (Bagci and Babaç, 2003). Multivariate analyses done by these authors segregated only a part of the compared populations to the taxa correctly and, not surprisingly, A. equi-trojani appeared close to A. bornmuelleriana but also intermingled among samples of A. cilicica (Bagci and Babaç, 2003).…”

“…From the needle characteristics, the arrangement of needles on the branchlet, needle length, needle width, needle thickness, position of the resin canals, and form of the needle apex are utilized in the species descriptions and in the keys to distinguish between them (Chater, 1964;Coode and Cullen, 1965;Liu, 1971;Yaltırık, 1993;Christensen, 1997;Farjon, 2010). These characters were also used in a comparative study between the Abies species that occur in Turkey (Bagci and Babaç, 2003). Multivariate analyses done by these authors segregated only a part of the compared populations to the taxa correctly and, not surprisingly, A. equi-trojani appeared close to A. bornmuelleriana but also intermingled among samples of A. cilicica (Bagci and Babaç, 2003).…”

“…Within the latter set, cone length and diameter, cone scale shape, cone bract shape, and the level of insertion among the cone scales are recognized as essential to distinguish between species (Yaltırık, 1993;Bagci and Babaç, 2003;Farjon, 2010;Kurt et al, 2016). From the needle characteristics, the arrangement of needles on the branchlet, needle length, needle width, needle thickness, position of the resin canals, and form of the needle apex are utilized in the species descriptions and in the keys to distinguish between them (Chater, 1964;Coode and Cullen, 1965;Liu, 1971;Yaltırık, 1993;Christensen, 1997;Farjon, 2010).…”
