“…The climatic factors Eref, MAT, and DD > 5 were correlated with DD < 18 and altitude. This correlation pattern effectively differentiates between the populations from the Balkan Mountains and those from the Dinarides [5]. The research conducted on two conifer species (Norway spruce and silver fir) in the same environment with specific environmental conditions reveals that the species have different mechanisms of adaptation for the same environment.…”

“…The decline in the number of silver fir (Abies alba Mill.) individuals is recorded throughout its distribution area [1], resulting from pollution, soil acidity, and rapid climate change [2][3][4][5][6]. With droughts and high temperatures in recent decades, genetic variability is one of the most important factors that can contribute to the species' adaptation [7], and it plays a crucial role in maintaining the entire forest ecosystem [8].…”

“…With droughts and high temperatures in recent decades, genetic variability is one of the most important factors that can contribute to the species' adaptation [7], and it plays a crucial role in maintaining the entire forest ecosystem [8]. Degradation of forests leads to a reduction in the size of populations, which further affects the reduction of genetic variability in the next generation, and this has a significant impact on the condition and sustainability of forest ecosystems [5,9]. The genetic variability level in these populations results from evolutionary processes, including how individual species respond to environmental changes [10].…”

“…These studies have included isozyme studies [10,12,13], chloroplast microsatellite DNA [12,[14][15][16], and mitochondrial DNA analyses [12,[17][18][19][20]. Additionally, research has confirmed the presence of genetic variability of needle morphological traits within populations [5] and has also highlighted the genetic potential of spatially separated populations [21]. Knowledge of the phenotypic variability of silver fir is necessary due to the decline of these forests being due to the species' sensitivity to temperature changes, lack of water, and air pollution [22].…”

The survival of marginal/peripheral silver fir (Abies alba Mill.) populations in the broader region of Southeast Europe is endangered due to climate change and population decline. This study aimed to determine the level and pattern of variability for the anatomical traits of needles and the possibility of linking the pattern of phenotypic variability with environmental factors. In most of the analyzed needle traits, the statistically significant variability between populations was determined. According to the results of the multivariate principal component analysis, it is evident that the populations are distinct from each other, in three groups. The climatic factors Hargreaves reference evaporation, mean annual temperature, and growing degree-days, were statistically significantly correlated. The altitude and heating degree-days are statistically significantly correlated with the following three environmental factors: Hargreaves reference evaporation, mean annual temperature and growing degree-days, but negatively with others. The paper’s findings indicate significant moderate and high correlations between the anatomical traits of the needles’ central bundle diameter with the resin duct diameter, the distance between the vascular bundle and the resin duct and the epidermis thickness with cuticle, the resin duct diameter with the distance between the vascular bundle and the resin duct and the epidermis thickness with cuticle, as well as the distance between the vascular bundle and the resin duct with the hypodermis height and the epidermis thickness with cuticle. The results of agglomerative hierarchical clustering analysis, performed for anatomical and climatic traits, confirmed the existence of three groups of tested populations according to the altitude gradient. Research results provide knowledge on the diversity and structure of Abies alba populations of Southeast Europe, important for further research and guidelines for the species’ conservation and genetic variability preservation in the southern marginal distribution area and keeping in line with climate change projections.

Phenotypic variation analysis and comprehensive evaluation are important tools for selecting provenances of forest trees, which, in turn, is crucial for genetic improvement of forest trees. The study analyzed eight needle-leaf and fourteen tracheid trait indexes of ten provenances of Qinghai spruce forest stands. Multiple comparisons, correlation analysis, cluster analysis, and principal component analysis were used to evaluate the differences in needle-leaf and tracheid traits among the different provenances. The study found significant differences in the needle-leaf and tracheid traits among the provenances. All traits included 50 pairs of positive and 26 pairs of negative correlations. The coefficient of variation for the tracheid trait (18.86%) was higher than that for the needle-leaf trait (17.20%). A comprehensive evaluation of needle-leaf and tracheid traits was conducted using principal component analysis. The study demonstrated that the degree of variation in needle-leaf and tracheid traits among the provenances of Qinghai spruce was extensive, with a multitude of sources of variation. Therefore, it is crucial to strengthen the selection of good provenances in the early seed selection process. The results of the comprehensive evaluation can be utilized as a foundation for the selection of good provenances for carbon sequestration and timber properties.
