Abstract:
Scots pine (Pinus sylvestris L.) is, together with Norway spruce, one of the most common forest tree species in Europe. Forests of Scots pine in this area (Balkan Peninsula), are at the south border of its natural range. Concerning the natural range, Scots pine occupies relatively small area and stock volume in comparison to other species (3% of total wood stock volume of state forests in Republic of Srpska – entity in Bosnia and Herzegovina). A provenance test of Scots pine in Bosnia and Herzegovina was established in Sokolac area in 1989. The total area of the test is 1.16ha. The provenance test consists of 13 provenances. Eleven of them originating from natural stands and 2 of them are from seed orchards. The test was set in a block system; each provenance was represented by 200 trees (40 trees in 5 blocks). In 2015 survival rate of different provenances was observed as well as the number of forked steams, which is consequence of bud damage in the early stage of development. Number of died trees under the influence of biotic and abiotic factors also was recorded. Later on, the all trees in the provenance test were measured (height and DBH). The providence of Zavidovići had the smallest number of forked steams and the largest number had Bugojno provenance. The largest number of dried trees was recorded for provenance Kladanj, but for the lowest number was recorded for provenance. Concerning the result of the study of taxation elements (DBH and height) the provenance of Romania Glasinac attained the highest values. The average height was 13,81 meters and DBH was 17,21 cm. The lowest values were recorded for provenance SPS average height was 10,89 meters and provenance Kladanj DBH was 14,74 cm. One of main goals of provenance research is identification and segregation of provenance that have best adaptation in selected ecological area, also goal of research is to follow phenotypic properties of individual provenances and influence of environment on their adjustment processes.
