AB  - Natural wild cherry populations in Serbia are a part of the southern border of this valuable forest tree species distribution range. The survival of these marginal provenances in Serbia as well as in the wider region is threatened by climate change, small population sizes, low competitiveness, etc. Therefore, it is recommended to artificially assist population regeneration while increasing their genetic diversity. Although knowledge of the amount and pattern of the specie's genetic diversity is a prerequisite for its effective conservation and use, related research in the region is scarce. The main goal of this study was to determine the amount and pattern of phenotypic variability of natural wild cherry populations in Serbia. Possible link between revealed pattern of phenotypic variability and genetic differentiation of the provenances was discussed. Fruits were collected in nine natural populations. Ten morphological traits of the fruits were measured, and average germination rate of the provenances was assessed. The least variable trait was the fruit width (CV = 6.2%), while the most variable trait was the petiole thickness (CV = 29.4%). Analysis of variance revealed significant among-provenance variation for investigated fruit characteristics (p  lt 0.01; alpha = 0.05), except for the petiole thickness (p = 0.92). Although variability among provenances was significant, the level of within-population variability was much higher (41.2-52.1%) than among-provenance differentiation (5.3-15.2%). The pattern of among-provenance variation was determined by a correlation analysis between provenance mean values and their climatic-geographical variables, whereby fruit thickness and petiole length proved to be useful diagnostic traits. Mean fruit thickness was significantly and positively correlated with altitude (R = 0.69; p = 0.04), annual precipitation as snow (R = 0.80; p = 0.01), and annual degree-days below 0 degrees C (R = 0.70); p = 0.04). The average petiole length was significantly and negatively correlated with the annual precipitation as snow (R = -0.69; p = 0.04), while it was positively correlated with annual heat to moisture index (R = 0.71; p = 0.03). The results revealed an ecoclinal pattern of phenotypic differentiation among the provenances due to their habitat's altitude and other ecological variables closely related to altitude. Although this study basically dealt with phenotypic variability of wild cherry fruits originating from natural populations, the results indicate likelihood for genetic differentiation of the provenances due to altitude. This likelihood provides the basis for recommending vertical seed zonation, as well as congruent use of reproductive material for assisted restoration of wild cherry populations in Serbia. However, to confirm this presumption of ecoclinal pattern of genetic differentiation, it is necessary to conduct analyses of various phenotypic traits in common garden experiments (e.g. provenance trials) as well as analyses of appropriate DNA markers.

AB  - Information on public attitudes towards the use of transgenic trees in forest plantations is important in the decision-making process and policy implementation for safe tree development, particularly at the EU level. In Europe, the use of transgenic forest trees is very limited and therefore such information is completely lacking. To address this issue within the FP0905 European COST Action on the Biosafety of Transgenic Forest Trees a pioneer cross-country pilot survey on public attitudes towards the use of transgenic forest trees was conducted using young population as a focus group. This was decided mainly because this focus group represents the future consumers, policy makers or developers. Specifically, the survey aimed to: i) assess the level of young people's knowledge about transgenic forest trees, ii) identify issues of concern to them regarding the cultivation of transgenic forest trees and iii) explore whether they approve or disapprove of the use of transgenic forest trees in plantations. Purposive sampling was performed and university students of different disciplines were included in the research as sampling subjects. In total, 1868 completed questionnaires from 15 European and non-European countries were analyzed. The young educated people that took part in the survey appeared to approve of the use of transgenic forest trees in plantations and would be willing to buy forest transgenic products. The potential loss of biodiversity due to a risk of gene flow between transgenic and wild trees was seen as the safety issue of most concern when considering the commercial release of transgenic forest trees. However, a serious perceived lack of knowledge about potential benefits and risks of the cultivation of transgenic forest trees was recorded in most of the countries. K-means clustering was implemented on respondents' positive responses to identify potential country patterns. No differences in patterns of public attitude towards the acceptance of the commercial growing of transgenic forest trees were observed between European and non-European countries. Extended research on public attitude issues towards the use of transgenic forest trees is strongly recommended as a basis for policy implementation on safe tree development.

AB  - Fifteen provenances of European beech (Fagus sylvatica L.) were evaluated for stability and adaptability by height growth at four test sites in Bosnia and Herzegovina (1), Croatia (1) and Serbia (2). Provenance trials were established in spring 2007 by planting 2- and 3-year old seedlings and arranged in a randomized complete block design. The data from seven 6-year-old and eight 5-year-old provenances were obtained in 2009 and analyzed separately. Finlay and Wilkinson's regression analysis and Additive main effects and multiplicative interaction model (AMMI model) were used to assess provenance by site interaction (P x S) and to identify beech provenances that have high and stable performance in different environments, at the juvenile stage of development. Analysis of variance showed that effects of provenance, site, and P x S interaction are highly significant (p  lt  0.001) in both age groups. Linear regression model evidenced that most of the provenances had regression coefficients not significantly different from unity (b=1.0), except for provenances Sjeverni Dilj Caglinski (HR24) and Vranica-Bistrica (BA59). The partitioning of the total sum of squares (SS) exhibited that the site effect was the predominant source of variation in both age groups of provenances (50.7% and 38.5%, respectively). Additionally, regression analysis explained 15.8% and 33.2% of provenance by site interaction terms, in provenances age six and five years, respectively, while the AMMI analysis accounted for 62.2% and 78.7% in P x S interaction. The results of AMMI showed that the first principal component (PC1) was statistically significant in both age groups. Adaptability and stability of provenances to the test sites were estimated with AMMI1 and AMMI2 biplots. Provenance Sjeverni Dilj Caglinski (HR24) showed constant performance over tested sites, characterizing with above average height growth at low yielding environments. Provenances HR25 and BA61 showed the opposite type of adaptation, being adapted to high yielding sites. Provenance Valkonya (HU42) was characterized by IPCA1 score close to zero and above average mean height growth, suggesting general adaptation to the tested environments. The implication of P x S was discussed in light of impact of climate change on beech and selection of most suitable provenances for future reforestation programs.
