The paper studies the morphological variability of the service tree populations in the continental and Mediterranean regions of Croatia. The inter- and intra-population variability, as well as eco-geographic population differentiation, was established on the basis of eight measured morphological characteristics of two types of leaflets (lateral and terminal) and two derived ratios, using descriptive and multivariate statistical methods. The conducted research established a high variability of morphological characteristics. In comparison with lateral leaflets, terminal leaflets showed a higher degree of variability for the majority of the studied variables. The differences between the trees within populations, as well as the differences between populations, were confirmed for all studied characteristics. The study also confirmed a trend of population variations according to the eco-geographic principle. Populations from climatically different and geographically distant habitats, in other words from the Mediterranean and the continental region, differed in the majority of studied characteristics. In addition to the established pattern of ecotypical variability between the continental and the Mediterranean regions, the clinal variability with regard to altitude and mean annual temperature was also confirmed. Small, although statistically significant clinal variability with regard to the longitude was recorded for two measured characteristics. The conducted study provided insights into the variability of the service tree populations in Croatia, which is a basis for further research that should be implemented in order to produce guidelines for the breeding and conservation of genetic resources of this rare and endangered noble hardwood species.

The subject of the study was a dynamic population of Sorbus torminalis resulting from spontaneous regeneration from seeds in northern Poland. The population, occupying a fenced plot of 1.72 ha in Forest District Jamy, amounted to 579 individuals. The spatial structure of population and some basic individual traits of trees were recorded, then the growing space of individual trees was examined. The following measures of tree growing space were investigated: crown diameter and projection area, and tree volume. The spatial structure of population was non-random, and there was evidence for effects of population density on tree performance. The observations have to be continued in order to describe optimal growing space of wild service tree; the results could be used to improve in situ conservation of this rare and valuable species.
