Abstract. One-year old needles from 50 silver fir trees in the Jata Reserve were characterized in respect to 12 morphological and anatomical features, and the data were analyzed statistically to determine variability between trees. From graph of discriminant analysis, dendrogram and minimum spanning tree it was concluded that individuals within the population generally were homogenous for those features and population was characterized by low level of variability, however several trees were distinct from others. The traits of needle which clearly differentiated individuals were: width of needle, height of needle, distance from resin canals to needle edge and distance from resin canals to vascular bundle.

Key words: silver fir, Abies alba, variability, needles, statistical analysis.
