Annotation:
Two subspecies of European beech (Fagus sylvatica L.) can be found in southeast Europe: Fagus sylvatica ssp. sylvatica L. and Fagus sylvatica ssp. orientalis (Lipsky) Greut. & Burd. (Fagus orientalis Lipsky). In a previous study, based on genetic diversity patterns and morphological characters, indications of hybridization between both subspecies were found in northeastern Greece, a known contact zone of F. sylvatica and F. orientalis. Nevertheless, potential genetic admixture has not been investigated systematically before. Here, we investigated genetic diversity and genetic structure of 14 beech populations originating from Greece and Turkey as well as of two reference F. sylvatica populations from Germany based on nine expressed sequence tag-simple sequence repeat (EST-SSR) markers. Very low genetic differentiation was detected among F. sylvatica populations (mean GST: 0.005) as well as among F. orientalis populations (mean GST: 0.008), but substantial differentiation was detected between populations of the two subspecies (mean GST: 0.122). Indications for hybridization between both subspecies were revealed for one population in Greece. One of the genetic markers showed specific allele frequencies for F. sylvatica and F. orientalis and may be used as a diagnostic marker in future studies to discriminate both subspecies.

AbstractGenetic variation is a major component of plant development and adaptation, and recent studies have shown that genetic variation among plant species can have important ecological effects. Oriental beech (Fagus orientalis Lipsky) is a dominant tree species in the Hyrcanian forests, where it occupies approximately 18 % of the forested area. In this study, nine expressed sequence tag simple sequence repeat (EST-SSR) markers were used to determine the genetic diversity and structure of Iranian Oriental beech populations growing at different altitudes. We further compared the genetic structures of the Iranian populations to a F. orientalis and a Fagus sylvatica L. population from the hybrid zone of the two taxa in southeast Europe, and to a F. sylvatica population from central Europe. All populations showed a high genetic diversity, which was similar to other F. orientalis and F. sylvatica populations from Europe. The genetic differentiation among Iranian beech populations was very low. In contrast, distinct genetic differentiation was found between the Iranian populations and the analyzed European populations (F. orientalis and F. sylvatica). One EST-SSR was identified to differentiate (GST: 0.503) between F. orientalis and F. sylvatica with very pronounced allele frequency differences between taxa. Specifically, the Fagus sylvatica characteristic allele 189 was almost absent from all Iranian populations and present in low frequencies in F. orientalis populations from other regions. This study helps to extend the knowledge of genetic diversity and genetic structure of Iranian Oriental beech populations. It further gives insights into the genetic differentiation between F. orientalis populations from the center and the edge of the species’ distribution range as well as between Oriental and European beech.

The paper deals with the variability of tree-ring width, with the density and swelling (volumetric swelling and swelling in individual anatomical directions) of wood from two different locations. Further, the variability of the explored properties along the stem radius is researched. The ring analyses show that the ring width decreases along the stem radius from the pith to the stem outer perimeter. Location 2 (a lower altitudinal vegetation zone) had on average wider rings (a statistically insignificant difference), higher density and higher volumetric swelling of wood in comparison with location 1 (a statistically significant difference). The relation between volumetric swelling and wood density has been confirmed. The results show that the wood density and its volumetric swelling change along the stem radius. With the increasing wood density the volumetric swelling also increases. The average density of beech wood from both locations is 752 kg/m<sup>3</sup> with moisture content of 12%.

Annotation:
The different growth patterns of the beech tree are described from a morphological and architectural point of view in the first part of this paper. In about 10 years, individuals can achieve various forms, according to the growth pattern. About thirty architectural variations are examined in the second part of this study; they reveal a surprising diversity within the species. In seedlings, the interindividual variations confer upon small beeches distinct "social status." In a regeneration, the silviculturist distinguishes individuals as well and poorly grown. This distinction into categories can henceforth rely on an architectural basis. Light and genetics have an important influence on the architecture of young beeches.

This study sought to develop a method to quantify tension wood areas in stem discs. It was suggested that the shiny appearance of beech (Fagus sylvatica L.) could provide an indication of tension wood. Each of 21 stem discs were digitised and the images analysed. Small areas of the discs were selected, and from these areas, anatomical sections were stained with astra-blue and safranine and the stained sections were compared with the wood disc images. The analysis showed that the shape of shiny areas and tension wood were similar; moreover, the measured ratios of shiny wood and tension wood were in good agreement. This confirms the assumption that in Fagus sylvatica shiny wood corresponds to tension wood.

Abstract Cross-species amplification of six microsatellite markers from European beech (Fagus sylvatica Linn) and nine markers from Japanese beech (Fagus crenata Blume) was tested in American beech (Fagus grandifolia Ehrh.). Three microsatellites from each species were successfully adapted for use in American beech and were found to be highly polymorphic, with 4-22 alleles at each locus and an expected heterozygosity value of 0.291 to 0.913. Twenty-five trees (including two clonal clusters) from a mature stand were sampled and genotyped to compute population statistics. No linkage disequilibrium between pairs of loci was detected, and the marker loci indicated that the population is at Hardy- Weinberg equilibrium. The markers were also used to genotype two full-sibling families consisting of a combined total of 99 individuals and were found to contain sufficient genetic information to assign paternity using a maximum likelihood method.
